[0062]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 and second reactors 310, 320, the feedstock is substantially liquefied by breaking intermolecular bonds using increased temperature and the reaction between the water and metal catalyst initiators. Feedstock is broken into short chain hydrocarbon radicals, ready to combine with others and polymerize. In third reactor 330, t...

Abstract

A method for producing synthetic fuels is provided. The process can involve the reaction of metals with water to liberate hydrogen, which can attack the feedstock molecules and with elevated temperature and pressure, reform the feedstocks into liquid fuels. These can be used as is or refined and used as gasoline, diesel fuel, aircraft fuel or burned to produce heat for uses such as generating electricity. The process can be environmentally friendly, producing no net greenhouse gases.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to provisional application No. 60 / 927,552, 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 increasing exponentially and concomitantly the readily available world petroleum supply has diminished. Governments and industrial concerns are dedicating increased attention to al...
