Fluid catalytic cracking (FCC) is one of the most important conversion processes in deep processing used in petroleum refineries. It is widely used to convert the high-boiling, high-molecular weight hydrocarbon fractions of petroleum crude oils to light oils of more varieties and better quality, such as more valuable gasoline, olefinic gases, and other products. By the atmospheric and vacuum distillation process, the light fuel oils can only be obtained to 10 – 40% of the crude oil. And the remainder is heavy oil and residuum are quite poor in quality, which is the feedstock to an FCC is usually that portion of the crude oil that has an initial boiling point of 340 deg C or higher at atmospheric pressure and an average molecular weight ranging from about 200 to 600 or higher. This portion of crude oil is often referred to as heavy gas oil or vacuum gas oil (HVGO). The FCC process vaporizes and breaks the long-chain molecules of the high-boiling hydrocarbon liquids into much shorter molecules by contacting the feedstock, at high temperature and moderate pressure with a FCC catalyst.

Pt CO Combustion Promoter is used to convert the carbon monoxide generated by the FCC Units to carbon dioxide, to reduce the carbon deposit on the regenerated catalyst, maintain the activity of the catalyst. Also it can help to save energy, give a stable operation and increase the yield of light oil, also the use of CO Promoter can reduce the pollution.
