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.
Claims22
A process for making chemical products from waste solid sustainable carbon materials, the process comprising:
- providing waste solid sustainable carbon material to a gasifier;
- gasifying the waste 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 in a first converter and the hydrocarbon in the second stream in a second converter 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 from the one or more converted streams;
- sequestering at least a portion of the separated CO2 in a sequestration facility;
- and
- producing at least one of methanol, diesel fuel, jet fuel, gasoline, or blendstocks of diesel fuel, jet fuel, and gasoline from the conversion feed,
- wherein a % of net atomic carbon input into the process from fossil-derived sources is between 15% and 50%,
- such methanol product has a well-to-wake GHG LCA that is less than 0.34 mt CO2e/mt of such product,
- such diesel fuel, jet fuel, gasoline, or blendstocks of diesel fuel, jet fuel, and gasoline product has a well-to-wake GHG LCA that is less than 0.72 mt CO2e/mt of such product, and
- such well-to-wake GHG LCA is computed based on such product being combusted downstream as a fuel.
(canceled)
An apparatus for making organic chemical products, the apparatus comprising
- a waste solid sustainable carbon material gasification stage comprising a gasifier to form CO, H2, CO2, and organic molecules from the waste solid sustainable carbon material, and a converter to convert the waste solid sustainable carbon material 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 CO2 removal unit to remove CO2 and form a conversion feed;
- a conduit to route removed CO2 to a sequestration facility;
- and
- a conversion stage to produce a chemical product from the conversion feed.
(canceled)
A process for making chemical products, the process comprising:
- providing waste solid sustainable carbon material to a gasifier;
- reacting the waste solid sustainable carbon material with oxygen and CO2 in the gasifier to gasify the waste solid sustainable carbon material and 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 from the one or more converted streams;
- sequestering at least a portion of the separated CO2 in a sequestration facility;
- and
- producing one or more chemical products from the conversion feed.
