Reforming of naphtha
WebSep 1, 2013 · Naphtha reforming catalyst is a bifunctional catalyst consists of a metal function, mainly platinum, and an acid function, usually chloride alumina. The metal function catalyzes the hydrogenation and dehydrogenation reactions and the acid function promote the isomerization and cyclization reactions [11], [12], [13].

WebThe Aromax process was developed because the conventional reforming catalysts showed poor selectivity particularly in the conversion of light naphtha to aromatic molecules with high octane number, thus more or less creating an “orphan stream”: the C 6 –C 7 stream is on the high end of the applicability range of isomerization, and on the low end of the … WebCatalytic reforming of naphtha replaced the earlier thermal reforming process and became the leading process for upgrading fuel qualities to meet the needs of higher-compression engines.
WebJan 1, 2014 · The heaviness (distillation endpoint) and type (lean or rich) are indicators of the difficulty in reforming the naphtha. For example, light-lean naphtha with an endpoint of 320 °F (160 °C) and 65 wt.% paraffins is more difficult to reform than a heavy-rich naphtha with an endpoint of 370 °F (188 °C) and 60 wt.% naphthenes plus aromatics.
