Catalytic Reformer is a reformation technique where light petroleum distillate (naphtha) is contacted with a platinum containing catalyst at elevated temperatures and hydrogen pressures ranging from 345 to 3450 kPa (50 to 500 lb/in2 gauge). This process, also called the UOP Platforming ™ Process, produces a high octane liquid product that is rich in aromatic compounds. Chemical hydrogen, light gas, and liquified petroleum gas (LPG) are also produced as reaction by-products.
The feedstock is gas oil and the cracking reaction takes place in the riser reactor. The catalyst is cleaned off with hot air in the regenerator.
Molecules in the feedstock usually have 30-40 carbon atoms. The riser reactor is a 60m x 2m tube. Hot vapourised hydrocarbons and powdered catalyst are fed in the bottom and forced up by steam. The catalyst acts as a fluidised bed.
