Reforming reaction chemistry
WebJun 29, 2024 · reforming. Reforming is a thermal or catalytic refining process in which the hydrocarbon molecules of petroleum are rearranged to improve its octane number; the … WebCatalytic reforming is the process of transforming C7–C10 hydrocarbons with low octane numbers to aromatics and iso-paraffins which have high octane numbers. It is a highly endothermic process requiring large amounts of energy. …. Isomerization is a mildly exothermic reaction and leads to the increase of an octane number.
