    Abstract: Disclosed is a method for producing hydrocarbon-containing feedstocks. In said method, the starting material is autothermally turned into a crude gas containing H 2 and CO as main components as well as the components CO 2 , H 2 O, CH 4 , and traces of H 2 S, COS, C n H m , N 2 , and Ar by means of non-catalytic partial oxidation at 1200 to 1500°C and pressures of 15 to 100 bar abs , and the CO contained in the crude gas is then converted into CO 2 and additional H 2 by adding steam. In order to improve said method, the converted crude synthesis gas is directly, i.e. without undergoing a washing process to remove CO 2 and H 2 S, separated into highly pure H 2 and a gas mixture containing H 2 S, CO 2 , H 2 , CO, CH 4 , Ar, and N 2 in a pressure change-absorption process, the gas mixture is fed to a tail gas wash of a sulfur recovery process, the separated H 2 S is fed into the processing gas of the sulfur recovery process, and the waste gas of the tail gas wash is burned, said waste gas being mixed with the tail gas of the sulfur recovery process.

    Abstract: A system and process for gas homogenization is disclosed. This has application in the areas of generation of gas and its conversion to electricity in downstream applications. The homogenization system minimizes variance in the gas characteristics (composition, flow, pressure, temperature), thereby rendering a steady stream of gas of consistent quality to the downstream machinery. This homogenization system can be adjusted to optimize the output gas stream for specific end-applications, or to optimize the output gas stream for different input feedstocks. This ensures that overall conversion efficiencies are maximised while keeping the process cost-effective. Such a uniform, steady output gas stream has a wide range of applications in the broad areas of generation of electricity (e.g. using internal combustion engines and combustion turbine engines), chemical synthesis (e.g. of compounds such as ethanol, methanol, hydrogen, methane, carbon monoxide, hydrocarbons), fuel-cell technologies and in polygeneration processes (processes that result in co-production of electricity and synthetic fuels).

    Abstract: A method for recycling the waste heat generated from an external process, which is fuelled by syngas, into a gasification process to enhance the energy density of the syngas produced as well as the overall gasification efficiency of the system. A method is provided for utilizing the waste heat contained in a stream exiting in the syngas fueled process to vaporize water and produce steam. The steam is then upgraded by first exchanging energy with the hot syngas exiting the gasifier and then within the gasifier itself to a temperature where significant steam gasification of the biomass occurs. The process within the gasifier is driven by introducing a small amount of air into the gasifier such that some biomass is directly combusted to provide the heat required by the process.
