PROCESSES FOR PRODUCTION OF LIQUID FUEL

摘要

A first process which comprises fractionating a stock oil which contains normal paraffins, oxygen-containing compounds and olefins and exhibits distillation properties involving a final point of 360°C or below into a first fraction and a second fraction with the boundary point falling within the range of 130 to 160°C and hydrorefining the first and second fractions respectively with a first catalyst and a second catalyst which each comprise both a carrier containing a solid acid and a Group VIII metal of the periodic table supported on the carrier. A second process which comprises bringing a stock oil containing paraffin-base hydrocarbons into contact with a supported platinum catalyst prepared from a carrier containing both crystalline aluminosilicate and an amorphous solid acid and a platinum compound free from constituent chlorine element to conduct hydrocracking of the oil and thus obtain a cracked oil.
