International Classification:

C07C 27/00

US Classification:

518700, 518702, 518703, 518704, 518705, 518706

Abstract:

A method and apparatus for converting carbonaceous material to a stream of methane and carbon monoxide rich gas by heating the carbonaceous material in a fluidized bed reactor using hydrogen, as fluidizing medium, and using steam, under reducing conditions at a temperature and pressure sufficient to generate a stream of methane and carbon monoxide rich gas but at a temperature low enough and/or at a pressure high enough to enable the carbonaceous material to be fluidized by the hydrogen. In particular embodiments, the carbonaceous material is fed as a slurry feed, along with hydrogen, to a kiln type reactor before being fed to the fluidized bed reactor. Apparatus is provided comprising a kiln type reactor, a slurry pump connected to an input of the kiln type reactor, means for connecting a source of hydrogen to an input of the kiln type reactor; a fluidized bed reactor connected to receive output of the kiln type reactor for processing at a fluidizing zone, and a source of steam and a source of hydrogen connected to the fluidized bed reactor below the fluidizing zone. Optionally, a grinder can be provided in the kiln type reactor.

International Classification:

C10G 1/02
C10G 1/00

US Classification:

208402

Abstract:

A process for the plasma-assisted treatment of coal in which coal is directly converted to heavy hydrocarbons. The first step in the process is direct conversion of coal to aliphatic hydrocarbons under plasma conditions in the presence of light hydrocarbons, such as natural gas. In the second process step, the aliphatic hydrocarbons are upgraded to a liquid fuel. The energy for the process can be provided by radio frequency energy, such as microwave energy, that is powered by a renewable energy source. The process has flexibility to adjust aromatic content in the fuel to match fuel specification requirements.

International Classification:

C10G 1/02
C10B 57/00
B01J 19/00

US Classification:

585240, 422165, 201 25

Abstract:

A method for producing a fuel composition from a feedstock which may contain biomass and municipal solid waste is described. The method includes the step of pyrolyzing the feedstock in the presence of a transition metal, using microwave energy, so that the level of oxygen in at least one product of the pyrolysis is reduced. An integrated process is also described, in which the transition metal can be regenerated. Moreover, pyrolysis products such as bio-oils can be upgraded to liquid fuel compositions. Related systems for producing fuel compositions are also described.

International Classification:

B01J 7/00
C10J 3/00

US Classification:

48 61, 48197 R, 48210

Abstract:

A gasifier system which includes a reactor; a feedstock inlet; an oxidant inlet; a raw product gas outlet; and a recycle conduit, is provided. The reactor usually includes an upper section, a central section, and a lower section. The feedstock inlet is disposed in the upper section of the reactor to receive a carbonaceous feedstock. The oxidant inlet is disposed in the lower section of the reactor to receive an oxidant. The raw product gas outlet is disposed in the upper section of the reactor. The recycle conduit is configured to couple the raw product gas outlet to the lower section of the reactor, and to recycle a raw product gas from the upper section of the reactor to the lower section of the reactor. A method for converting a carbonaceous stream into a product gas in a gasifier system is also provided.
