A feedstock delivery system transfers a carbonaceous material, such as municipal solid waste, into a product gas generation system. The feedstock delivery system includes a splitter for splitting bulk carbonaceous material into a plurality of carbonaceous material streams. Each stream is processed using a weighing system for gauging the quantity of carbonaceous material, a densification system for forming plugs of carbonaceous material, a de-densification system for breaking up the plugs of carbonaceous material, and a gas and carbonaceous material mixing system for forming a carbonaceous material and gas mixture. A pressure of the mixing gas is reduced prior to mixing with the carbonaceous material, and the carbonaceous material to gas weight ratio is monitored. A transport assembly conveys the carbonaceous material and gas mixture to a first reactor where at least the carbonaceous material within the mixture is subject to thermochemical reactions to form the product gas.

The invention relates to an arrangement for preparing a gas in a closable reactor by supplying the reactor with carbon-based biomass or chopped wood material, such as chips, in substantially oxygen-free conditions, by allowing the biomass or wood material to gasify at a high temperature, and by recovering the gas generated in a gasification reaction. In that the arrangement the reactor has its interior defined by a feed pipe whose inlet end is closable with a shut-off valve, especially with a ball valve, and whose outlet end adjoins a heatable gasification dome, biomass or chopped wood material is delivered from the feed pipe's inlet end into the reactor's interior, the reactor's interior is supplied with free water/water vapor in its supercritical state, which is optionally prepared catalytically by splitting water/water vapor, the biomass or wood material is conveyed into a gasification space of the reactor's interior, which is in connection with the heated gasification dome and which is adapted to have existing conditions selected in a manner such that the water present in said gasification space is present in its supercritical state, and the gas generated in the gasification reaction is recovered.

Implementations of a non-polluting biomass processor, and manufactured processor components are disclosed which at least partly address the local technical problems of a municipality, business, and/or organization, to generate non-polluting emissions, while generating at least one, often two or more, product outputs from biomass feedstocks input into the biomass processor. Examples of the operations of the biomass processor and various combinations of its manufactured processor components are disclosed. The product outputs may include carbon char and/or activated carbon, both of which may be used to increase water retention in climates with hot, dry summers and/or used to remediate water pollution in water reservoirs.

The invention relates to a device (100) for converting carbonaceous dry raw materials (MPCS) into a synthesis gas, comprising a MPCS pyrolysis chamber (110); a port (106) for introducing the MPCS into said pyrolysis chamber (110); and a port (108) for extraction of synthesis gas from said pyrolysis chamber (110). The device (100) further includes a central chamber (120) immersed in said pyrolysis chamber (110) and comprising a port (128) allowing only a gaseous communication between said central chamber (120) and said pyrolysis chamber (110); and an oxygen injection port (132) in said central chamber (120) for oxidizing at least one portion of the pyrolysis gases passing from the pyrolysis chamber (110) to the central chamber (120).

A biomass gasification furnace provided with an outer tube, an inner tube provided inside the outer tube so that a lower end thereof is located higher than a lower end of the outer tube, and a reactor that heats the outer tube from outside, wherein a combustion air supply portion that supplies combustion air is provided inside the inner tube so as to be spaced from the lower end of the inner tube, a biomass raw material is supplied from above to the inside of the inner tube so as to form an accumulation portion in which the biomass raw material has accumulated from the lower end of the outer tube to a location higher than the combustion air supply portion, a fuel gas is produced in the accumulation portion, and the produced fuel gas is discharged through a space between the inner tube and the outer tube.

A feedstock delivery system transfers a carbonaceous material, such as municipal solid waste, into a product gas generation system. The feedstock delivery system includes a splitter for splitting bulk carbonaceous material into a plurality of carbonaceous material streams. Each stream is processed using a weighing system for gauging the quantity of carbonaceous material, a densification system for forming plugs of carbonaceous material, a de-densification system for breaking up the plugs of carbonaceous material, and a gas and carbonaceous material mixing system for forming a carbonaceous material and gas mixture.
