Typically, there are several processes in each refinery to convert crude oil into various products, including gasoline, gas oil and kerosene (jet fuel). One of the most important refinery units is the Naphtha Reforming process. In this process, as its name implies, all reactions are directed towards paraffin compounds being branched and cyclic compounds.

At present, the capacity of catalytic conversion processes in different parts of the world is about 12 million barrels per day. The catalysts of this process typically have two extruded or spherical bases of mainly gamma alumina and the active ingredient platinum along with other metals such as rhenium, tin and iridium. The following table presents the technical specifications of the catalyst under the AFR20 brand for the Semi-regenerative catalytic reformer unit.
