First Claim
Patent Images
1. A method for making sequesterable biochar from a carbon-containing input, comprising:
- subjecting a carbon-containing input to a pyrolysis process to obtain a volatile gas stream and an inert carbonaceous solid, wherein the volatile gas stream and the inert carbonaceous solid are formed as separate components in the process and wherein a portion of the carbon from the carbon-containing input is contained in the inert carbonaceous solid;
converting the volatile gas stream to one or more of combustible fuels, fuel blend stocks, refinery or chemical feedstock, refinery or chemical intermediates or chemicals; and
removing hydrocarbons from the inert carbonaceous solid to provide a sequesterable biochar.

Abstract
A method and process is described for producing negative carbon fuel. In its broadest form, a carbon-containing input is converted to combustible fuels, refinery feedstock, or chemicals and a carbonaceous solid concurrently in separate and substantially uncontaminated form. In an embodiment of the invention, biomass is converted via discrete increasing temperatures under pressure to blendable combustible fuels and a carbonaceous solid. The carbonaceous solid may be reacted to synthesis gas, sold as charcoal product, carbon credits, used for carbon offsets, or sequestered.
