Patent ID: 8038743

Claim:
A system for reforming diesel fuel into hydrogen comprising: feeds for water and diesel fuel; a supercritical water (SCW) reactor in fluid communication with said water feed and said diesel fuel; at least one pump in fluid communication with said diesel fuel feed and configured to pressurize said diesel fuel feed to a predetermined pressure at or greater than the critical pressure of water before the water and the diesel fuel are mixed in the SCW reactor; at least one pump in fluid communication with said water feed and configured to pressurize said water feed to a predetermined pressure at or greater than the critical pressure of water before the water and the diesel fuel are mixed in the SCW reactor; at least one pre-heater in thermal communication with said water feed, said diesel fuel feed and said pumps that is configured to heat water from said water feed and diesel fuel from said diesel fuel feed to a predetermined temperature equal to or greater than the critical temperature of water before the water and the diesel fuel are mixed in the SCW reactor; a water-gas shift (WGS) reactor; and a hydrogen capturing system; wherein, said SCW reactor reforms said diesel fuel into a synthesis gas comprising a mixture of hydrogen and carbon monoxide and outputs said synthesis gas; wherein said synthesis gas output by said SCW reactor is fed into said WGS reactor which converts said carbon monoxide into carbon dioxide and hydrogen and outputs an output gas including a higher percentage of hydrogen to carbon monoxide compared to said synthesis gas, and said hydrogen in said output gas is captured by said hydrogen capturing system.
