Patent ID: 8231776

Claim:
A method for obtaining a petroleum distillate product comprising: (a) subjecting an untreated light Fischer-Tropsch liquid having oxygenates containing between 1 mass % and 20 mass % oxygen to a hydrogenation in a first reaction zone, in the presence of a first catalyst comprising an amorphous substrate having a first metallic composition embedded therein to obtain a hydrotreated light Fischer-Tropsch liquid composite and yielding water as a by-product; (b) subjecting the hydrotreated light Fischer-Tropsch liquid composite to a hydrogenation for isomerization and cracking in a second reaction zone, in the presence of a second catalyst comprising a molecular sieve substrate or a zeolite having a second metallic composition embedded therein to obtain the petroleum distillate product; and (c) recovering the petroleum distillate product, wherein the untreated light Fischer-Tropsch liquid has distillation temperatures of about 90° C. at the 10% recovery point and about 370° C. at the 90% recovery point.
