Catalysis is a process in which a substance speeds up a chemical reaction without being consumed or altered in the process. Substances that can accomplish this remarkable feat are called catalysts and are of immense importance in chemistry and biology. In chemistry, a catalyst is a substance that speeds up the rate of a reaction without itself being consumed in the reaction.Catalysis may be divided into two main types homogeneous and heterogeneous. Homogeneous catalysis is catalysis in a solution by a soluble catalyst. Homogeneous catalysis assigns to reactions where the catalyst is in the same state as the reactants, particularly in solution.
Heterogeneous catalysis is one where the reaction components are not in a similar phase. Enzymes and other biocatalysts are frequently considered as a third category. Similar mechanical principles apply to heterogeneous, homogeneous, and biocatalysis.
A catalyst is another substance than reactants products added to a reaction system to alter the speed of a chemical reaction approaching a chemical equilibrium. It interacts with the reactants in a cyclic manner promoting perhaps many reactions at the atomic or molecular level, but it is not consumed. Another reason for using a catalyst is that it promote the production of a selected product. A catalyst that is in a separate phase from the reactants is said to be a heterogeneous, or contact, catalyst. Contact catalysts are materials with the capability of adsorbing molecules of gases or liquids onto their surfaces. An example of heterogeneous catalysis is the use of finely divided platinum to catalyze the reaction of carbon monoxide with oxygen to form carbon dioxide. This reaction is used in catalytic converters mounted in automobiles to eliminate carbon monoxide from the exhaust gases.
Nanotechnology catalytical techniques are having a profound impact on clean energy research and development, ranging from hydrogen and liquid fuel production to clean combustion technologies. In this area, catalyst stability is paramount for technical application, and remains a major challenge, even for many conventional catalysts.Thermal stability in particular is a challenge across many currently discussed technical applications and an obstacle for many nanocatalyst-enabled devices, from sensors to fuel production. In particular fuel processing technologies (hydrogen and/or liquid fuel production from fossil and renewable resources, clean combustion) typically proceed at particularly severe conditions (high temperatures, high through-put, contaminated fuel streams, etc) and hence require particular attention to catalyst stabilization, but even many processes at much lower temperature conditions, such as fuel cells, are still looking for catalysts with improved stability.

It also uses numerical analysis and data structures to solve and analyse problems that involve fluid flows.

Heat is defined in physics as the transfer of thermal energy across a well-defined boundary around a thermodynamic system. The thermodynamic free energy is the amount of work that a thermodynamic system can perform. Enthalpy is a thermodynamic potential, designated by the letter "H", that is the sum of the internal energy of the system (U) plus the product of pressure (P) and volume (V). Joule is a unit to quantify energy, work, or the amount of heat. Heat transfer is a process function (or path function), as opposed to functions of state; therefore, the amount of heat transferred in a thermodynamic process that changes the state of a system depends on how that process occurs, not only the net difference between the initial and final states of the process. Thermodynamic and mechanical heat transfer is calculated with the heat transfer coefficient, the proportionality between the heat flux and the thermodynamic driving force for the flow of heat. Heat flux is a quantitative, vectorial representation of heat-flow through a surface.
In the chemical industry and industrial research, catalysis assume an essential part. Distinctive catalysts are in consistent advancement to satisfy financial, political and natural requests. When utilizing catalyst, it is conceivable to replace a contaminating chemical reaction with an all the more environmentally friendly alternative. Today, and in future, this can be crucial for the chemical industry. For an organization, a new and improved catalyst can be an enormous preferred standpoint for a competitive assembling cost. It's amazingly costly for an organization to shut down the plant because of a blunder in the catalyst, so the right choice of a catalyst or another change can be critical to industrial achievement.

Scanning electron microscopy can show the appearance of zeolite crystals, e.g. their sizes and morphologies, and can also be used to look into the cores of crystals revealing any abnormal microstructures, which often help us to elucidate actual crystal growth mechanisms. High resolution transmission electron microscopy is a powerful tool to directly image many pore systems and local defects in zeolites.
