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 to energy and an exhaust comprising CO2 in connection with drying 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.
An apparatus for making organic chemical products, the apparatus comprising:
- a solid sustainable carbon material processing unit configured to reduce moisture in a second solid sustainable carbon material and comprising an energy conversion unit and a drying unit, wherein,
- the energy conversion is configured to convert a first solid sustainable carbon material into energy and an exhaust containing CO2;
- and,
- the drying unit is configured to apply the energy produced by the energy conversion unit to form a dried solid sustainable carbon material from the second solid sustainable carbon material;
- a gasification stage comprising a gasifier coupled to the solid sustainable carbon material processing unit to receive the dried solid sustainable carbon material to form CO, H2, CO2, and organic molecules from the dried solid sustainable carbon material, and a converter to convert the organic molecules to CO, H2, and CO2;
- a source of fossil-derived hydrocarbon coupled to the converter;
- a CO converter to convert CO to H2 and CO2;
- a first CO2 removal unit to remove CO2 and form a conversion feed;
- a second CO2 removal unit to remove CO2 from the exhaust of the energy conversion unit;
- a conduit to route removed CO2 to a sequestration facility;
- and
- a conversion stage to produce a chemical product from the conversion feed.
A process for making chemical products containing carbon from solid sustainable carbon materials, the process comprising:

- 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
