A process for the conversion of biomass to a liquid fuel is presented. The process includes the production of diesel and naphtha boiling point range fuels by hydrocracking of pyrolysis lignin extracted from biomass.

The present invention relates to the conversion of solid biomass to liquid fuels and specialty chemicals. The process utilizes an activating step to make the biomass more susceptible to conversion, that is the biomass is broken down such that the components of the biomass are dissociated. Subsequently, the activated biomass undergoes a reaction to convert it to a bio-oil.

A process for the conversion of biomass to a liquid fuel is presented. The process includes the production of diesel and naphtha boiling point range fuels by hydrotreating and hydrocracking of lignin in the biomass in a one step process.

Treatment of waste water from a biomass-to-liquid process, said process comprising producing synthesis gas from biomass and conversion of said synthesis gas into liquid hydrocarbons by a Fisher-Tropsch process. The waste waters obtained are purified in common with waste waters from another industrial process to which said biomass-to-liquid process is integrated, such as in forestry, power and / or heat generation, waste incineration or a process in a metal-, petrochemical and / or oil refining industry. The biomass-to-liquid. process and said another industrial process may have a common feed water process unit, a common cooling water process unit and a common waste water treatment unit. The waste water treatment process may comprise a biological purification process and said Fischer-Tropsch process may utilize a cobalt catalyst. An integrated factory comprising a biomass-to-liquid plant and another industrial facility in which both plants are connected to a common waste water treatment facility is also described.

Combined microwave heating and plasma / electric arc heating is utilized in several processes and apparatus which involve co-production of pig iron and high quality syngas, biomass to liquid fuel production, coal to liquid fuel production, co-gasification of biomass and coal, municipal solid waste treatment, waste-to-energy (agriculture waste, ASR and PEF), EAF dust and BOF sludge treatment to recover zinc and iron, hazardous bottom ash vitrification, and bromine, chlorine and sulfur removal / recycling.

Disclosed is a process for the alteration of the ratio of the specific gravities of the oil and water phases resulting from the conversion of biomass to liquid products, the reduction of the conductivity and of metals of the product mixture, which each can aid in the removal of solids contained in the oil phase; and a liquid-liquid extraction method for partitioning desirable carbon containing compounds into the oil phase and undesirable carbon containing compounds into the water phase.

The present description is related to the field of hydrocarbon production by gasification of carbonaceous material. It provides a two-stage gas washing method as a part of gas refining. More specifically it discloses a method for hydrogen sulfide and carbon dioxide removal from synthesis gas produced by gasification. It introduces a use of a novel combination of wash approaches for this application. As a specific application, this process is utilized as a part of biomass to liquid (BTL) process.

Technologies to convert biomass to liquid hydrocarbon fuels are currently being developed to decrease our carbon footprint and increase use of renewable fuels. Since sugars / sugar derivatives from biomass have high oxygen content and low hydrogen content, coke becomes an issue during zeolite upgrading to liquid hydrocarbon fuels. A process was designed to reduce the coke by co-feeding sugars / sugar derivatives with a saturated recycle stream containing hydrogenated products.

A method of catalytically preparing a fluid product from solid carbonaceous material is described. In the method, at least one of the following equilibria is established by one or more catalysts: a) CH3OH=CO+2H2, b) CO+H2O=CO2+H2. In some versions, the solid carbonaceous material is woody biomass. Components of the fluid product can include one or a combination of C5-C9 alcohols. In certain versions, the method can be practiced with substantially all of the carbon in the carbonaceous material being converted to the fluid product. Also, in some versions, the fluid product can be prepared with substantially no char formation. The fluid product of various versions can be used directly as fuel or as a reagent for preparing commodity chemicals without the need for separating the fluid product components.
