Disclosed is a phosphorus coal gasification reaction device for combined production of yellow phosphorus and syngas, including a stock bin, a mineral aggregate lock hopper, a phosphorous coal gasification reactor, a slag quench chamber and a slag lock hopper. In the phosphorous coal gasification reactor, a drying zone, a dry distillation zone, a combustion zone, a phosphate rock reduction zone, and a slag bath zone are formed from top to bottom. A gas product outlet communicating with the phosphorous coal gasification reactor is installed at a top of the phosphorous coal gasification reactor, two to eight fuel burners are symmetrically arranged on the combustion zone, and an auxiliary burner communicating with the slag bath zone is arranged at the bottom of the slag bath zone. The reactor device can improve the production capacity of the yellow phosphorus, and reduce the emission of CO.sub.2.

A method can be used for operating a descending moving bed reactor with flowable granular material. The method involves: (i) filling an upper lock-hopper with granular material and/or emptying a lower lock-hopper, (ii) purging the lock-hoppers with purging gas, and (iii) filling the reaction chamber containing a descending moving bed from the upper lock-hopper and/or emptying the reaction chamber into the lower lock-hopper. The pressure equalization between the reaction chamber and lock-hopper is achieved with product gas. The method then involves: (iv) optionally, relieving the lock-hoppers and conveying the product gas flow into the product line, and (v) purging the lock-hoppers with purging gas.

The Biopowerplant is a system that integrates the generation of carbon-neutral energy through the cultivation and conversion of microalgal biomass, with sewage sanitation and environmental carbon recovery, with the additional and secondary production of biofertilizer, biofuel, water for reuse. This system integrates a suboptimal anaerobic digestion subsystem focused on the generation of biogas, the processing of the resulting digestate through a microalgal consortium culture subsystem with biofilm induction and smooth decreasing gradient of light radiation, and the transformation of the generated microalgal biomass into syngas through a subsystem of evaporation, torrefaction, pyrolysis, gasification, and combustion in separate chambers. The syngas and methane from the biogas are subsequently used as fuel in an electric power generator capable of operating with mixed gases. The biogas generation process is enriched through the recirculation of the microalgal biomass supernatant, the residual heat from the syngas generation subsystem, and the heat transferred from the combustion gases of the electric generator. The residual sludge from the biogas generation subsystem is recirculated towards a longitudinal biopile subsystem, where it acts as an anaerobic medium compared to the aerobic medium that constitutes the concentrated microalgal biomass, and both streams are mixed to be transformed into the syngas generation subsystem. Input inflows for system operation are mainly sewage, and optionally seawater and/or leachate. The inflows must be bioaugmented with a microalgal consortium dosed automatically by a Compact in situ bioaugmentation system, preferably more than 3 kilometers before the inflow enters the system.

A process for pressurizing bulk material in a hopper; wherein the hopper is configured as a lock hopper (29) containing a bulk material, a source of pressurized gas, lines (22, 26, 28) to convey the pressurized gas from the source to one or more inlets (30) of the lock hopper, a valve arranged in the lines, wherein the opening position of said valve (34, 35) is controlled to provide pressurizing gas to the lock hopper at a preset constant gas volume flow rate.

A method and system for continuous production of contaminant free and size specific biochar using downdraft gasification of variable quality feedstock. The system and process of the present invention includes the transfer of biochar from a gasifier after gasification to a temperature-controlled cooling screw conveyor, into a drum magnet for ferrous metal removal into multiple diverters to separate and remove ungasified materials and non-ferrous metal contaminants, then transferred into a granulator for grinding and screening the biochar to a pre-selected size. By directly attaching a novel and continuous product treatment process to the biochar stream as it exits the gasifier, the particle size, moisture content, carbon content and yield of a contaminant free biochar product can be narrowly controlled and improved to meet strict product quality specifications required by specialty applications.

The invention relates to a installation (4) for recycling composite materials comprising a horizontal reactor (5) with a first zone (1), second zone (2) and third zone (3), which are leak-tight and independent, aligned with and separated from one another by means of gates that allow the passage of the composite material to be recycled only when the process has ended in a previous zone. The first zone (1) comprises a rotation mechanism (9) for rotating the material and gas outlet means (8). The second zone (2) comprises air injectors (10) and gas outlet means (11). The third zone (3) comprises cooling means. The invention also relates to a method for recycling composite materials comprising a first pyrolysis phase, a second gassing phase for gassing the material resulting from the first phase, and a third cooling phase for cooling the reinforcement material.

Feed materials are introduced into the reactor. The reactor further includes a buffer section and a pre-treatment section, which adjoins a bottom of the buffer section to create a cross-sectional enlargement. An intermediate section adjoins the pre-treatment section. An upper oxidation section adjoins a bottom of the intermediate section and includes tuyeres in at least one level. An upper reduction section adjoins a bottom of the upper oxidation section. The reactor further includes a gas outlet section. The reactor further includes a countercurrent section having a conical lower reduction section and a conical lower oxidation section adjoining the conical lower reduction section having at least one tuyere and at least one tapping.

A gas generation plant for generating hydrogen-containing synthesis gas includes a gas generation reactor which is oriented in the vertical direction being greater in length vertically than width. A gas inlet is designed for the passage of superheated water vapor into the gas generation reactor. Through an upper outlet, a gas/water vapor mixture can exit the gas generation reactor and be reused in the second heating element after having been superheated. Synthesis gas can exit through a lower gas outlet. In the vertical direction, the gas inlet is arranged at a smaller distance from the lower end than the lower gas outlet. The upper gas outlet is arranged at a smaller vertical distance from the upper end than the lower gas outlet. The vertical distance between the upper gas outlet and the lower gas outlet is greater than the vertical distance between the lower gas outlet and the gas inlet.
