Catalysis and Reaction Engineering

It consist of two types actual and potential catalysis which are part of Biocatalysis and Biotransformation that includes  whole cells or isolated components therefore natural and modified enzymes and catalytic antibodies for the synthesis of interconversion or degradation of chemical species.  It is the chemical modification that is occurred by the influence of an organism or by the presence of enzymes in the biological system which is known as Biotransformation. The process of transformation of chemicals that are used in biological catalysts like enzymes, antibodies, cell constituents are called as Biocatalysis.The Enzymatic reactions and biotransformations  are catalyzed by fungal enzymes are  used in industry, agriculture, food technology, and medicine.

It is designed to stimulate the process by focusing on the development and application of efficient synthetic methodologies and strategies in organic and bio-organic pharmaceutical natural product macromolecular and materials chemistry that are used for Advanced Synthesis & Catalysis.  The targets of synthetic studies which range from the natural products and pharmaceuticals to macromolecules and organic materials are used. While catalytic methods mainly  depends on  metal complexes or enzymes plays an increase the role  in for achieving synthetic efficiency of all areas of interest to the practical synthetic chemist. Advanced Synthesis and Catalysis includes synthesis design reaction techniques and separation science and process development.

Catalysis plays an important role in the chemical industry and industrial research. For Different catalysts are in the constant development to fulfill the economic, political and environmental demands. While using a catalyst, it is possible to replace a polluting chemical reaction with a more environmental friendly alternative. Today and for the future, this may take a vital role in the chemical industry. In addition, to this it’s important for a company/researcher to pay attention to the market development. If a catalyst is not continually improved by the company, then another company might take progress in research on that particular catalyst and can gain market share value. A new and improved catalyst can be a huge advantage for a competitive manufacturing cost for a company. That it’s extremely expensive for a company to shut down the plant because of an error in the catalyst, so that the correct selection of a catalyst or a new improvement can be key to industrial success.

Reaction engineering is mainly important for chemical engineering or industrial chemistry is dealing with the chemical reactors. Then Frequently these term relates specifically to the catalytic reaction systems where both a homogeneous or heterogeneous catalyst is present in the reactor. a reactor is not present by itself at Sometimes, but rather it is integrated into the process, then the issue of solvent effects on reaction kinetics, and it is also considered as the integral part .Chemical Reaction Engineering accept the modern chemical industry and aim is to achieve high-quality products and minimize the unwanted by-products which is particularly important for Selectivity in the reactor by processes in which by-products cause environmental problems.

Catalysis in Green Chemistry and Engineering is related to the use of catalyst in green process and sustainable engineering, and then it’s mainly related to the catalyst synthesis, characterization and its applications which are primarily to reduce waste associated with the usage of materials and energy in a given process in consonance. To develop a sustainable production processes and which reduces the impact on the environment to an acceptable level and that allows self-depuration processes of the living environment. Catalytic agents enables for a broad range of chemical reactions that are fundamental to Industrial and consumer products from plastics to pharmaceuticals, solvents to soap, and fuels to food.

Organometallic chemistry  which deals with the study of organometallic compounds and the chemical compounds. It contains atleast taking a one chemical bond between the carbon atom of an organic molecule and a metal, and it includes alkaline, and alkaline earth, and transition metals, and it broadened to include a metalloids like boron, silicon, and tin, From a side of bonds to organyl fragments and bonds to 'inorganic' carbon, like carbon monoxide, cyanide, or carbide, are generally considered as organometallic. Associated compounds such as transition metal hydrides and metal phosphine complexes are generally included in organometallic compounds. The term "metalorganic compound" refers to metal-containing compounds lacking direct metal-carbon bonds contains a organic ligands. The organometallic chemistry combines the aspects of traditional inorganic and organic chemistry in these field.

The branch of engineering specifies about the study and principles of chemistry, physics, mathematics, biology, and economics to effective use, and produce, design, transport and transform energy and materials, Chemical engineers work can range from the use of Nano-Technology and Nano-Materials in the laboratory to  a large-scale industrial processes that transform chemicals, raw materials, microorganisms, living cells and energy into useful methods of products.Chemical engineers are involved in many aspects of plant design and operation, which includes safety and hazard assessments, and  the process design and modeling, analysis, nuclear engineering, control engineering, biological engineering, chemical reaction engineering, construction specification, and operating instructions are involved.

The chemical process industry aspects a marvelous task of delivering, growing and always more demand of global population with the products we required. The average effectiveness at which resources are changed into the final products are still dramatically low and which is almost clear solution to perform chemical conversions at much higher yields and selectivity, this is where active and selective catalysts are efficient chemical reactors.It plays an important role for presenting that how to enhance the efficiency of catalysts and reactors, and The most important developments in the field of chemical reactor engineering and industrial catalysis. In addition, many ways of improving efficiency, activity, selectivity, and improved methods for scale–up, modeling and design are presented in a solid manner.

Novel reactor deals with process intensifications tools like capillary reactor, then it also deals with the chemical process industries, and due to this distinct high specific interfacial area are obtainable from heat and mass transfer, that increases the transfer rates and improves the safety process. It provides a motivation for exploring the three similar tools, like capillary micro reactor, spinning disc, and rotating tube reactors. Process intensification is a chemical and process design pathway that leads to considerably smaller, cleaner, safer and more energy-active process technology. Beyond the chemical and process industries, and deals about the developing successful PI solutions and which deliver savings and ability which demands the engineers to work with important-edge process technologies and these involved in research and development of chemical process, pharmaceutical, bioscience systems, and environmental.

Most of the products are produced from the chemical and petroleum industry utilizes a catalysts to increase the rate of reaction and refinement to the desired products. Catalysts are also broadly used to reduces a harmful byproduct pollutants in environmental applications. Enlarge the reaction rates and converts to the higher production volumes at lower temperatures with smaller and less exotic materials of construction needed. While a highly selective catalyst is used, and large volumes of desired products are produced with essentially no undesirable byproducts. Diesel, Gasoline, home heating oil, and aviation fuels owe the performance quality to catalytic processing used to upgrade the crude oil.

Chemical kinetics is also named as the reaction kinetics, and which is the branch of physical chemistry that is concerned with perceptive rates of chemical reactions. When it is compared with the thermodynamics, approaches the direction in a process. It explains about insignificant rate, and the study of Chemical kinetics in this method. The experimental conditions impacts the speed of a chemical reaction and yield information, then the reaction's mechanism and transition states, are also the construction of mathematical models defines the characteristics of a chemical reaction.

Heterogeneous catalysts are commonly recognized as Nanomaterial-based catalysts, and in that Heterogeneous catalysts are destroyed up into metal nanoparticles in command to recover the catalytic process and Metal nanoparticles must have high surface area, which can increase the catalytic activity.
