摘要： A process for preparing methanol by a methanol synthesis reaction of carbon dioxide with hydrogen may involve a distillation step and a condensation step following the synthesis of a crude methanol. A volatile component and water may be separated off from a methanol-containing product stream, and a gas stream containing a volatile component that has been separated off may be discharged at least partially as offgas. At least part of the gas stream that has been separated off may be recirculated into the methanol synthesis reaction. A plant for preparing methanol can store or utilize electric power generated from renewable energy sources and provide facilities for discharging the offgas stream, which can be purified by catalytic after-combustion. Alternatively, the plant can be configured without discharge of an offgas substream, or the offgas streams are so small that they can be released without treatment into the environment at a suitable position.

摘要： A hydrogen separation filter includes a plurality of hydrogen extraction layers, a plurality of separation layers with hydrogen separation films, and a plurality of reformed gas layers, which are laid one upon another in the sequence of the extraction layer, the separation layer, the reformed gas layer, and the separation layer to form a laminate structure. The respective layers are composed of porous ceramic material to ensure the required strength. The direction of the gas flow in the reformed gas layers and that in the extraction layers are respectively fixed to simplify the gas intake and discharge structure. The hydrogen separation filter is covered with a casing via a cushioning member to ensure the sufficient strength and the required sealing properties. A methanation catalyst that accelerates methanation of carbon monoxide is carried on either the separation layer or the extraction layer. This arrangement effectively relieves the adverse effects of contamination of resulting hydrogen with carbon monoxide, due to a pinhole or a partial damage of the layers.

摘要： Biomass, including waste biomass, is gasified by a process in which the biomass is first carbonized, and the char and pyrolysis gas from the carbonizer are respectively fed to a high temperature gasifying part and a gas reformer part of a two-stage gasifier. A gasifying agent is continuously fed to the gasifying part, and intermittently fed to the gas reformer, to maintain the temperature required to avoid tar formation in the gas reformer stage. Multiple carbonization chambers are operated in rotation. When the carbonization/gasification apparatus is used to provide fuel to an electric power generator set, exhaust heat from the generator power plant is fed back to the carbonizer, and can be supplemented by exchange of heat from the gas delivered to generator power plant from the outlet of the gasifier.

摘要： A gaseous fuel mixer includes a venturi defining a flow area that decreases from an inlet opening to a throat. The throat coincides with a minimum flow area of the venturi. The gaseous fuel mixer further includes a fuel delivery body in the flow area extending transverse to a longitudinal axis of the venturi and positioned between the throat and the inlet opening. The fuel delivery body is adapted to introduce gaseous fuel into the venturi at a trailing edge thereof opposite the inlet opening. The trailing edge of the fuel delivery body substantially coincides with the throat.

摘要： An oxygen-based biomass solid fuel combustion system and method has an air separator for separating oxygen from air providing a supply of oxygen for feeding oxygen to a solid fuel combustion chamber. An airlock feeds a metered amount of solid fuel to the solid fuel combustion chamber. A burner stage having a firetube for collecting fuel gases from the solid fuel combustion chamber combusts the collected fuel gases with further oxygen from the separator and heats a boiler to generate steam. A heat utilization device (e.g. an electrical generator) may be connected to the steam boiler. Nitrogen-free diluent gases (e.g. argon and carbon dioxide) are used to control combustion process temperatures. The usable heat energy and useful byproducts are extracted from the different stages of the process.
