Abstract: The present disclosure relates to a processes and systems for producing fuels from biomass with high carbon conversion efficiency. The processes and systems described herein provide a highly efficient process for producing hydrocarbons from biomass with very low Green House Gas (GHG) emissions using a specific combination of components, process flows, and recycle streams. The processes and systems described herein provide a carbon conversion efficiency greater than 95% with little to no GHG in the flue gas due to the novel arrangement of components and utilizes renewable energy to provide energy to some components. The system reuses water and carbon dioxide produced in the process flows and recycles naphtha and tail gas streams to other units in the system for additional conversion to syngas to produce hydrocarbon-based fuels.

Abstract: The disclosure relates to methods, systems, and apparatus arranged and designed for converting non-methane hydrocarbon gases into multiple product gas streams including a predominately hydrogen gas stream and a predominately methane gas steam. Hydrocarbon gas streams are reformed, cracked, or converted into a synthesis gas stream and methane gas stream by receiving a volume of flare gas or other hydrocarbon liquid or gas feed, where the volume of hydrocarbon feed includes a volume of methane and a volume of non-methane hydrocarbons. The hydrogen contained in the syngas may be separated into a pure hydrogen gas stream. A corresponding gas conversion system can include a super heater to provide a hydrocarbon feed/steam mixture, a heavy hydrocarbon reactor for synthesis gas formation, and a hydrogen separator to recover the hydrogen portion of the synthesis gas. The gas conversion system can have a modal design such that it can operate to form hydrogen gas or alternatively operate to form synthetic natural gas with the same unit operation components.

Abstract: Process control parameters for production of hydrogen and FT products by steam/CO2 reforming include controlling steam reformer temperature, addition of steam, CO and optionally, biogas. Optimization of parameters have resulted in increased production of H2, removal of sulfur and halogen contaminants, and control of the H2/CO ratio for efficient generation of Fischer-Tropsch products.

Abstract: A method for producing an olefin product, including the steps of converting a hydrocarbon feedstock to an unsaturated hydrocarbon stream through a steam cracking process in an olefins production plant; combusting hydrogen to provide at least some of the heating duty to the steam cracking process, wherein the hydrogen has a carbon intensity less than about 1.0 kg CO2e/kg H2, wherein the hydrogen is produced using a hydrogen production process; providing at least some of the required energy for the hydrogen production process from a biomass power plant; and processing the unsaturated hydrocarbon stream to recover the olefin product. The olefin product may comprise ethylene having a well-to-gate carbon intensity less than about 0.6 kg CO2e/kg C2H4, or may comprise propylene having a well-to-gate carbon intensity less than about 0.6 kg CO2e/kg C3H6.

Abstract: A system is described for providing a hydrocarbon product stream. An electrolysis section provides a syngas stream from a first feed comprising CO2 and a second feed comprising H2O, which is then passed to an F-T section where it is converted to a hydrocarbon product stream and a tail gas stream. An electrical steam reformer section said tail gas stream and convert it to a second syngas stream, which is then recycled upstream the FT section. A process is also provided for converting a first feed comprising CO2 and a second feed comprising H2O to a first hydrocarbon product stream in a system according to the invention. The system of the invention can be combined with an upgrading section, in a gas-to-liquid plant.

Abstract: The present invention provides a process for the manufacture of a useful product from synthesis gas having a desired hydrogen to carbon monoxide molar ratio comprising: gasifying a first carbonaceous feedstock comprising waste materials and/or biomass in a gasification zone to produce a first synthesis gas; optionally partially oxidising the first synthesis gas in a partial oxidation zone to generate oxidised synthesis gas; reforming a second carbonaceous feedstock to produce a second synthesis gas, the second synthesis gas having a different hydrogen to carbon ratio from that of the first raw synthesis gas; combining at least a portion of the first synthesis gas and at least a portion of the second synthesis gas in an amount to achieve the desired hydrogen to carbon molar ratio and to generate a combined synthesis gas and subjecting at least part of the combined synthesis gas to a conversion process effective to produce the useful product. The reforming step enables the conventional water gas shift reaction to be dispensed with.
