Abstract
A process for treating a carbonaceous material includes reacting the carbonaceous material and a process gas in supercritical water to at least one of hydrotreat and hydrocrack the carbonaceous material to form a treated carbonaceous material. The process is preferably carried out in a deep well reactor, but can be carried out in conventional surface-based reactors at a temperature of at least 705° F. and a pressure of at least 2500 psi.
Claims16
A process for treating a carbonaceous material, comprising:
- reacting said carbonaceous material and a process gas in water in a reactor vessel to at least one of hydrotreat and hydrocrack said carbonaceous material,
- wherein said reacting is conducted at a temperature of at least about 300° F. and a pressure of at least 1000 psi and said reactor vessel is a deep well reactor.
