  • Process for reforming and dewaxing by selective hydrocracking of hydrocarbon fractions
    Patent number: 4124487
    Abstract: The process for selective hydrocracking of hydrocarbon fractions consists in that hydrocarbon fractions are contacted with hydrogen at a respective molar ratio of 1:2.5-20, a temperature of 280.degree. - 520.degree. C., and a pressure of 15 - 100 kgf/cm.sup.2 on a zeolite catalyst with a pore size of 4.6 to 6.0 A and containing 0.1 to 5 wt.% of metal of Group VIII of the periodic system, and a tervalent chromium cation with a minimum exchange capacity equal to 30 percent.The herein-proposed process for selective hydrocracking of hydrocarbon fractions is capable of upgrading petroleum products accompanied by producing a synthetic substitute of natural gas.
