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. Biomass is used to provide energy to dry solid sustainable carbon material to form dry sustainable carbon material to gasify. 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 chemical products from solid sustainable carbon materials, the process comprising:
- converting a first solid sustainable carbon material to energy and an exhaust comprising CO2, wherein the energy from converting the first solid sustainable carbon material is used to dry a second solid sustainable carbon material to produce a dried solid sustainable carbon material;
- sequestering at least a portion of CO2 from the exhaust in a sequestration facility;
- gasifying the dried solid sustainable carbon material to produce a first stream comprising CO, H2, CO2, and a mixture of organic compounds;
- providing a second stream comprising hydrocarbon derived from a fossil source;
- converting the organic compounds in the first stream and the hydrocarbon in the second stream into 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 the sequestration facility;
- and
- producing one or more chemical products from the conversion feed.
A process for making chemical products containing carbon from solid sustainable carbon materials, the process comprising:
- converting a first solid sustainable carbon material to energy and an exhaust comprising CO2, wherein the energy from converting the first solid sustainable carbon material is used to dry a second solid sustainable carbon material to produce a dried solid sustainable carbon material;
- sequestering at least a portion of CO2 from the exhaust in a sequestration facility;
- gasifying the dried solid sustainable carbon material to produce a first stream comprising CO, H2, CO2, and a mixture of organic compounds;
- providing a second stream comprising hydrocarbon derived from a fossil source;
- converting the organic compounds in the first stream and the hydrocarbon in the second stream into 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;
- controlling an amount of fossil-derived carbon in the conversion feed;
- sequestering at least a portion of the separated CO2 in the sequestration facility;
- and
- producing one or more chemical products from the conversion feed.
