摘要:
A method for the gasification of biomass, wherein the biomass feedstock is combined with a light hydrocarbon composition to form a slurry; followed by feeding the slurry to a gasifier to produce a fuel gas. In another embodiment, a method for the gasification of biomass is described. The method includes the steps of combining a biomass feedstock with water to form a slurry; feeding the slurry to a gasifier to produce a fuel gas; and injecting a light hydrocarbon into the gasifier, to generate gasification temperatures greater than about 900° C., by partial or complete combustion of the light hydrocarbon. In some other embodiments, the biomass gasifier product gas is coupled to a reformer, wherein a light hydrocarbon is injected to generate high temperatures.

A system for production of hydrogen comprises at least one steam reforming zone configured to receive a first fuel and steam to produce a first reformate gas stream comprising hydrogen using a steam reforming process. The system further comprises a mixed reforming zone configured to receive an oxidant to produce a second reformate gas stream comprising hydrogen, wherein the first reformate gas stream is sent to the mixed reforming zone to complete the reforming process.
摘要:
A method of producing a fuel composition from a bio-oil feedstock is provided, wherein the bio-oil feedstock is subjected to a step of oil extraction to produce a bio-oil and deoiled residue. At least a portion of the deoiled residue is gasified to produce a hydrogen-containing gas. The bio-oil is subjected to an upgrading process to ultimately produce a fuel composition. At least a part of the hydrogen-containing gas produced in the gasification of deoiled residue is used in the upgrading process of producing a fuel composition. The upgrading process, which can involve hydro-treating, hydroisomerization and at least one separation step, produces light hydrocarbons in addition to the product fuel composition. The light hydrocarbons can be used in the gasification operation, e.g., to reduce tar formation.

The disclosed embodiments relate to a method and system for regeneration of a catalyst. The system includes an engine that creates an exhaust stream and a fuel supply adapted to supply a fuel stream to the engine. A reactor includes a catalyst and is in fluid communication with the engine to receive the exhaust stream. A sensor senses a system parameter and produces a signal corresponding to the system parameter. A controller receives the signal and directs at least a portion of the exhaust stream or at least a portion of the fuel stream to the catalyst to control a regeneration operation based on a value of the system parameter sensed by the sensor.
