Preparation of Gas Turbine Engine Fuel from Synthetic Crude Oil Derived from Coal.

摘要

A 232gallon gas turbine fuel sample containing 23vol.% aromatics (20-25vol.% specification target) was prepared from synthetic crude oil (syncrude) derived from Western Kentucky coal. The seven fuel specifications designated as most important were all met with the exception of smoke point. The following major processing steps were used to prepare the sample:Initial distillations (atmospheric distillation of the syncrude to remove light hydrocarbons and water,and vacuum distillation to remove the material boiling above about 500F);Hydrogenation of the resulting kerosene fraction to produce a 20-25vol.% aromatics product;Final atmospheric distillation to remove light ends and produce a 140to 155F flash point product.
