PROCESS FOR THE THERMAL CRACKING OF RESIDUAL HYDROCARBON OILS

摘要

T 5171 PROCESS FOR THE THERMAL CRACKING OF RESIDUAL HYDROCARBON OILS Process for thermal cracking of residual hydrocarbon oils by 1) feeding the oil and a synthesis gas to a thermal cracking zone, the gas having a temperature sufficiently high to maintain the temperature in the cracking zone by means of direct heat exchange at 420-850 .degree.C, 2) separating the cracked products into (a) a gas, (b) one or more distillates and (c) a cracked residue, 3) separating the cracked residue into one or more heavy hydrocarbon oils poor in asphaltenes and one or more heavy hydrocarbon oils rich in asphaltenes, 4) gasifying the oil(s) rich in asphaltenes in the presence of oxygen and steam to produce synthesis gas, and 5) applying synthesis gas from 4) as synthesis gas in 1).
