What is a catalyst?
A catalyst is a substance effects on rates of reaction. In general, a catalyst changes rates of reaction by opening a different reaction pathway.
What is catalysis?
Catalysis is a reaction maintains the best conditions for rapid and accurate process. A catalyst lowers the activation energy to speed up the reaction but not effects on the result of process. A catalyst is divided into homogeneous catalyst and heterogeneous catalyst. Homogeneous catalyst is in the same phase as the reactants and heterogeneous catalyst is in the different phase from the reactants.
Methods of catalysis
Homogeneous catalyst is melt with single phase, such as n- isobutyl aldehyde. Heterogeneous catalysis can involve multiple phases. In general, the catalyst is a solid, and reactants are liquid or gas. Sometimes, there are reactants in liquid-gas phase such as production of benzene by dehydrogenation of cyclo-hexane.
Ilshin Autolcave's catalytic reactor is the equipment that can perform various catalysis with safety and accurate process.
Ilshin Autoclave Co., Ltd obtained ASME pressure vessels certification of design & manufacturing, also have Korea Gas Safety Corporation and The Korea Occupational Safety and Health Agency certification so can ensure safety.

| Applications of Catalysis |
| Petrochemical Industry |
• Oil refinery distills crude oil and performs hydrogenation, hydrogenolysis, catalytic cracking, isomerization or
alkylation to improve a quality of oil.
• Remove sulfur to prevent environmental pollution |
| Manufacturing chemicals |
• Most of processes manufacturing chemicals use a catalyst except pyrolysis and electrochemistry.
• Most of processes manufacturing polymer use a catalyst except radical polymerization. |
| Prevent Environmental Pollution and Remove Pollutants |
• To prevent air pollution due to the increase of automobiles, use catalytic converter for automotive exhaust emissions, which oxidize unburned hydrocarbon and carbon monoxide to become carbon dioxide and water,
and nitrogen oxide to become nitrogen and oxide
• Selective catalytic reduction(SCR) for removal of nitrogen oxide in power plant or nitric acid plant.
• Remove nitrogen oxide, which is a cause of acid rain and ozone depletion
•
Remove volatile organic substances such as an endocrine disruptor or pollutants in air or water by catalytic combustion. |
| Catalysis in Living |
• Fan heater, gas stove, air conditioner, air cleaner, gas alarm etc.
• The catalyst in air cleaner removes gas(sulfur dioxide) and bad smells for air cleaning. |
