Abstract
Benzene is one of the most famous aromatic compounds characterized by ringing and stability, which is formed by both natural processes and human activities. Benzene is also a substance found in hydrocarbons such as gasoline and hexane. International organizations for cancer research and global health have identified benzene as a carcinogen. Also, polymer grade hexane and in fact the same benzene-free hexane is widely used in the petrochemical and lubrication industries (food industry) of the country, which also requires reducing benzene from 6 to 2% to less than 50% ppm. Since partial and selective hydrogenation of benzene is performed because it is a heterogeneous process, ie at the surface...
