Naphtha reforming catalyst
WitrynaCatalytic naphtha reforming, in which low octane naphtha feedstock is converted into high octane reformate, is one of the core processes in modern refineries. 1,2 The reformate produced includes high-value aromatics for the petrochemical industry such as benzene, toluene, and xylenes (BTX). Hydrogen as a main byproduct is highly valued … WitrynaCatalytic reforming is a process whereby light petroleum distillates (naphthas) are contacted with a platinum-containing catalyst at elevated temperatures and hydrogen pressures ranging from 345 to 3,450 kPa (50–500 psig) for the purpose of raising the octane number of the hydrocarbon feed stream. The low octane, paraffin-rich naphtha
