Reforming is a process which uses heat, pressure and a catalyst (usually containing platinum) to bring about chemical reactions which upgrade naphthas into high octane petrol and petrochemical feedstock. The naphthas are hydrocarbon mixtures containing many paraffins and naphthenes. This naphtha feedstock can come from the crudes oil distillation or catalytic cracking processes and from thermal cracking and hydrocracking processes. Reforming converts a portion of these compounds to isoparaffins and aromatics, which are used to blend higher octane petrol.
– paraffins are converted to isoparaffins
– paraffins are converted to naphthenes
– naphthenes are converted to aromatics
