Abstract
Method and apparatus for converting waste solid sustainable carbon material to chemical products is described herein. The methods add hydrocarbon derived from fossil sources to gas derived from gasifying waste solid sustainable carbon material to enhance hydrogen availability, and in some cases carbon availability, for production of the chemical products. Carbon dioxide made by the process is at least partially sequestered to yield a chemical manufacturing process with environmental burden substantially less than conventional processes. Use of the hydrocarbon boosts yield of final products.

A process for making organic chemical products from solid sustainable carbon materials, the process comprising:
- providing solid sustainable carbon material to a gasifier;
- gasifying the solid sustainable carbon material to produce a first stream comprising CO, H2, CO2, and a mixture of organic compounds;
- converting the organic compounds in the first stream, using a first converter, and hydrocarbon in a second stream, using a second converter, the second stream comprising hydrocarbon derived from a fossil source, to CO, H2, and CO2, to form one or more gas streams comprising CO, H2, and CO2;
- converting at least a portion of CO in the one or more gas streams to CO2 to increase H2 in the one or more gas streams and to form one or more converted streams;
- separating CO2 from the one or more converted streams to form a conversion feed;
- sequestering at least a portion of the separated CO2 in an underground sequestration facility;
- and
- producing one or more organic chemical products from the conversion feed,
- wherein a % of net atomic carbon input into the process from fossil-derived sources is between 15% and 50%, and
- wherein the organic chemical products contain less than 10% carbon derived from a fossil source.
A process for making organic chemical products from solid sustainable carbon materials, the process comprising:
- providing solid sustainable carbon material to a gasifier;
- gasifying the solid sustainable carbon material to produce a first stream comprising CO, H2, CO2, and a mixture of organic compounds;

- converting at least a portion of CO in the one or more gas streams to CO2 to form one or more converted streams;
- separating CO2 from the one or more converted streams to form a conversion feed;
- sequestering at least a portion of the separated CO2 in an underground sequestration facility;
- and
- producing one or more organic chemical products from the conversion feed,
- wherein a percentage of carbon derived from a fossil source in the organic chemical products is less than a % of net atomic carbon input into the process from fossil-derived sources.
