    In this work a kinetic model for the naphtha catalytic reforming process is presented. The model utilizes lumped mathematical representation of the reactions that take place, which are written in terms of isomers of the same nature. These groups range from 1 to 11 atoms of carbon for paraffins, and from 6 to 11 carbon atoms for naphthenes and aromatics.

    Catalytic reforming - encyclopedia article - Citizendium

    Catalytic reforming is a catalytic chemical process used in petroleum refineries to convert naphthas, typically having low octane ratings, into high-octane liquid products called reformates which are components of high-octane gasoline (also known as petrol). Basically, the process re-arranges or re-structures the hydrocarbon molecules in the naphtha feedstocks as well as breaking some of the .
