[0084]The above examples show the variety of feedstocks that can be used in the system to produce different synthetic fuels in accordance with the invention. The type of synthetic fuel produced can be controlled by the type of initiator used as well as reaction conditions such as those within third reactor (330). It is understood that in first reactor (310) and second reactor (320), the feedstock is substantially liquefied by breaking intermolecular and intramolecular bonds using increased temperature and the reaction between the water and metal catalyst initiators. Feedstock is broken into short chain hydrocarbon moieties, ready to combine with others an...

Abstract

A system and method for producing synthetic fuels are disclosed in which a slurry comprised of a particulate solid portion and a carrier liquid portion is provided. The solid portion comprises (i) a feedstock of carbon-containing polymeric materials that are substantially free of each of halogen, sulfur and nitrogen atoms, and contain about 5 to about 25 percent by weight water, and (ii) a catalytic amount of metal particles. The carrier liquid portion is a hydrocarbon/oxyhydrocarbon composition. The feedstock constitutes about 10 to about 60 weight percent of the slurry. The slurry is heated anaerobically to provide an elevated temperature of about 250° to about 455° C. and a pressure of about 20 to about 50 atmospheres that are maintained for a time period sufficient to provide a combustible liquid fuel at least 80 percent of which contains about 6 to about 21 carbon atoms per molecule.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation-in-part of each of application Ser. No. 11 / 768,097, Ser. No. 11 / 768,057 and Ser. No. 11 / 768,073 that all were filed on Jun. 25, 2007 and claim priority to provisional application Ser. No. 60 / 927,552 filed on May 4, 2007, the contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]Wood and coal have been a principle source of fuel for hundreds of years. In modern times, petroleum has become a primary commodity for the generation of energy. Petroleum has had the advantages of relatively low cost and ease of transportation and storage because of its liquid consistency. Further, petroleum is readily amenable to fractionation and conversion into a variety of valuable industrial products such as fuels, building products, chemical intermediates and the like.[0003]International developments have led to increase in the price of this crude oil. The consumption of petroleum has been ...
