Claims
- 1. In a process for reforming hydrocarbons in which a gaseous mixture of a sulfur-containing liquid hydrocarbon selected from the group consisting of kerosene, gas oil and vacuum distillation gas oil, and an oxidizing agent for reforming is brought into contact with a catalyst to convert the mixture into a mixed gas containing hydrogen and carbon monoxide, the improvement comprising:
- (a) evaporating by heating said liquid hydrocarbon in the mixture of said oxidizing agent to form said gaseous mixture at a temperature of from 350.degree. C. to 600.degree. C.;
- (b) further heating said gaseous mixture from step (a) to a temperature above 800.degree. C. while passing said gaseous mixture through a bed of aluminum oxide and an alkali metal oxide and/or alkaline earth metal oxide;
- (c) passing said gaseous mixture from step (b) through a nickel-containing catalyst bed at a temperature above 800.degree. C. to convert said gaseous mixture into said mixed gas, said nickel-containing catalyst being composed of at least one metal oxide selected from oxides or beryllium, magnesium, calcium, strontium, barium and aluminum with nickel incorporating therein, whereby the sulfur compound contained in said liquid hydrocarbon is converted into readily desulfurizable H.sub.2 S and/or COS; and
- (d) passing said mixed gas discharged from step (c) countercurrently to the flow of said gaseous mixture of sulfur-containing liquid hydrocarbon and oxidizing agent in a heat-exchange zone passing through said bed of step (b) and said catalyst bed of step (c), whereby the sensible heat of said discharged mixed gas is utilized in said reforming and for heating up said gaseous mixture.
- 2. The process according to claim 1, wherein said step (c) is conducted at a temperature of from 900.degree. C. to 1000.degree. C.
