Embodiment Construction

[0029]FIG. 1 is a schematic view of a fuel production plant 10 in accordance with a preferred embodiment of the invention. Plant 10 comprises three general process sections: a size reduction section 200, a reaction section 300 and a finishing section 400, each shown in greater detail in FIGS. 2, 3 and 4, respectively.

[0030]A preferred embodiment of the invention comprises a size reduction step having multiple stages to gradually reduce the size of the feedstock to the desired particle size. Referring to FIG. 2, size reduction section 200 preferably comprises a first stage size reduction grinder 210, a second stage size reduction grinder 220, a third stage size reduction grinder 230, a fourth stage size reduction safety grinder 240 and a slurry storage tank 250. Acceptable grinders in accordance with preferred embodiments of the invention include the MultiShear and Arde Barinco brand grinders, from MultiShear Corporation of Graniteville, S.C. and Arde Barinco, Inc. of Norwood, N.J.

Abstract

A method for producing synthetic fuels is provided in which a feedstock containing polymers from a wide variety of sources is re-formed into a more satisfactory fuel source for producing heat, electricity, powering vehicles and the like. The feedstock can comprise scrap rubber, plastic and / or plant matter or other materials that are not particularly well suited for use as fuels in their existing state. The system can involve breaking long polymer molecules and / or carbohydrate molecules into shorter chain hydrocarbon radicals and then forming a fuel of hydrocarbons of selected length via what can be anaerobic and anhydrous reactions. 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...
