The hydrocracking of “hexane” (n-hexane 64.4%) was performed in a conventional fixed-bed down-flow system over the temperature range from 300° to 600°C, and under prsssure of 50 and 100kg/cm². The activity of the catalysts were found to be in the order of nickel>nickel-tungsten sulfide>tungsten sulfide>molybdenum sulfide>silica-alumina (“Neobead” alumina 85%).
Nickel was the most active catalyst, and the product was mostly methane, the formation of ethane and propane being only a small.
Other series of the catalysts (molybdenum sulfide, tungsten sulfide and nickeltungsten system) showed the lower activities than nickel. With these catalysts, ethane, propane and other intermediates, as well as methane were found to be formed in a considerable amount. It is expected that the hydrocracking with these catalysts proceeds via a different path from that with nickel catalyst.
