Abstract

A new field of the catalytic application of Pt/H-mordenite catalysts is presented for production of gasoline blending components having high octane number and reduced sulfur content (<10-50 ppm) required for satisfying environmental and human health regulations. Experiments were carried out over catalysts containing 0.3-1.0% platinum on H-mordenite of various acidity and on Pt, Pd/H-Y zeolite. The n-pentane fractions containing 61-184 ppm sulfur in the form of COS, CS2, beside Me-, Et-, i-Pr-thiol were converted at 200-280°C, 30-40 bar, 0.8-2.0 h-1 liquid hourly space velocity and hydrogen to hydrocarbon mole ratios of 1: 1 -2: 1. Under optimum process parameters the concentration of all sulfur compounds in the product was less than 1-2 ppm using the catalyst containing 0.6% platinum, preserving its strong metal function. During hydrodesulfurization the isomerization of n-pentane took place simultaneously with high conversion and selectivity approaching the thermodynamic equilibrium to 85-98%.
