摘要:
A process for converting lignocellulosic feedstock includes providing a lignocellulosic feedstock into a first inlet of a first reactor at a first end, and providing a hot feedstock into a second inlet of the first reactor at a second end of the first reactor. The process includes heating and reacting the lignocellulosic feedstock with the hot feedstock and outputting a first product stream from a first product outlet of the first reactor. The first product stream is an alkane rich product stream. A reactor system includes a first reactor having a first inlet at a first end, a second inlet at a second end and at least one product outlet. The first reactor is configured to receive a lignocellulosic feedstock at the first inlet and a hot feedstock at the second inlet. The system includes a second reactor having a first inlet downstream from the at least one product outlet.

Methods, systems, and devices for continuous fuel production are provided. Some embodiments may utilize two pyrolysis platforms, which may utilize biomass as a feedstock. One platform may generally utilize a high temperature pyrolysis process that may generate at least hydrogen and carbon monoxide. This high temperature gas stream may be fed into a lower temperature fast pyrolysis stream as a cover gas. The hot cover gas may react with the fast pyrolysis vapors hydrotreating while the vapors may still be hot and the molecules may still be small. The reacted product may then be distilled on the cool down. This may provide a rapid continuous process for the production of liquid fuels from biomass or other compounds that include carbon-oxygen-hydrogen (C—O—H) compounds.

A processor for vacuum distillation of whole tires including: an insulated housing having a door on one end, a central radiant heat tube and a plurality of peripheral heat tubes spaced about the central radiant heat tube and arranged with an inlet leg of each peripheral heat tube adjacent an outlet leg of another peripheral heat tube to maximize utilization of the radiant heat energy from the peripheral heat tubes. The central radiant heat tube has an unsupported end adjacent the door such that the tires loaded through door will pass over the central radiant heat tube and such that the central radiant heat tube is in a central opening of each tire.

Efficient biomass conversion systems, methods and apparatus utilize a fast pyrolysis unit installed at a sawmill or similar location where substantial quantities of biomass are generated, with the biomass generated at the sawmill fed into the fast pyrolysis unit under pyrolytic reaction conditions, and with exhaust gases containing entrained matter resulting from the pyrolytic reactions being separated into constituent char and bio-fuel constituents.

The present invention addresses the processing of waste and low-value products to produce useful materials in reliable purities and compositions, at acceptable cost, without producing malodorous emissions, and with high energy efficiency. In particular, the invention comprises a multi-stage process that converts various feedstocks such as offal, animal manures, municipal sewage sludge, tires, and plastics, that otherwise have little commercial value, to useful materials including gas, oil, specialty chemicals, and carbon solids. The process subjects the feedstock to heat and pressure, separates out various components, then further applies heat and pressure to one or more of those components. Various materials produced at different points in the process may be recycled and used to play other roles within the process. The invention further comprises an apparatus for performing a multi-stage process of converting waste products into useful materials, and at least one oil product that arises from the process.

A process for the recovery of coal particles from coal tailings is described. The process comprises the steps of initially treating the coal tailings to separate therefrom a proportion of the coal particles having sizes in a specified range, and then subjecting the coal particles to a heat treatment process. In one embodiment, the separated coal particles can undergo an agglomeration in oil prior to the heat treatment. The process provides a further means of recovering coal particles of certain sizes from slurries.
摘要:
In a coking process wherein coal is subjected to coking in chamber furnaces by means of combustion of a fuel gas in the heat flues of the furnace and transfer of the generated heat through the walls of the furnace, the heat supply is effected, during the entire course of the coking operation, according to a preestablished programmed control scheme related to a uniform or mean rate of heat supply, the supply of heat being at a maximum at the commencement of the coking operation and being gradually reduced during the continuing coking operation.
