Abstract
A hydrocarbon feedstock is brought into contact with activated carbon at a temperature of about 300.degree. to about 650.degree. C. and a pressure of about 0-1000 psig in the absence of added hydrogen to reduce the content of aromatic, sulfur and nitrogen compounds contained therein and to simultaneously lower the specific gravity thereof.

A process for upgrading a hydrocarbon feed stock containing sulfur compounds, nitrogen compounds, and aromatic compounds to reduce the sulfur, nitrogen, and aromatics contents, thereof and to simultaneously lower the specific gravity thereof which comprises:
- contacting said hydrocarbon feedstock, without any external supply of hydrogen or water at a temperature of about 300.degree. to about 650.degree. C. and a pressure of about atmospheric to -1000 psia,
- with a catalyst wherein the said catalyst consists essentially of activated carbon and
- recovering the lighter product hydrocarbon containing reduced concentrations of sulfur, nitrogen, and aromatics.
