摘要： An integrated process for the production of a useful liquid hydrocarbon product comprises: feeding a gasification zone with an oxygen-containing feed and a first carbonaceous feedstock comprising waste materials and/or biomass, gasifying the first carbonaceous feedstock in the gasification zone to produce first synthesis gas, partially oxidising the first synthesis gas in a partial oxidation zone to generate partially oxidised synthesis gas, combining at least a portion of the first synthesis gas and/or the partially oxidised synthesis gas and at least a portion of electrolysis hydrogen obtained from an electrolyser in an amount to achieve the desired hydrogen to carbon monoxide molar ratio of from about 1.5:1 to about 2.5:1, and to generate a blended synthesis gas, wherein the electrolyser operates using green electricity; and subjecting at least a portion of the blended synthesis gas to a conversion process effective to produce the liquid hydrocarbon product.

摘要： The invention relates to an electrolysis arrangement for alkaline electrolysis and a method for producing hydrogen and oxygen by electrolysis of an alkaline electrolysis medium. According to the invention, an anolyte deaerating means is arranged downstream of an anolyte gas-liquid separator and is arranged upstream of the electrolysis cell stack of the electrolysis arrangement, and/or a catholyte deaerating means is arranged downstream of a catholyte gas-liquid separator and arranged upstream of the electrolysis cell stack of the electrolysis arrangement. By this arrangement, the fact is exploited that many undesirable gas components have a much lower solubility in the alkaline electrolysis medium than in pure deionised water, which is supplied as fresh water to the electrolysis arrangement for compensation of the water consumed by the electrochemical reaction.

摘要： An environment control system utilizes oxygen and humidity control devices that are coupled with an enclosure to independently control the oxygen concentration and the humidity level within the enclosure. An oxygen depletion device may be an oxygen depletion electrolyzer cell that reacts with oxygen within the cell and produces water through electrochemical reactions. A desiccating device may be g, a dehumidification electrolyzer cell, a desiccator, a membrane desiccator or a condenser. A controller may control the amount of voltage and/or current provided to the oxygen depletion electrolyzer cell and therefore the rate of oxygen reduction and may control the amount of voltage and/or current provided to the dehumidification electrolyzer cell and therefore the rate of humidity reduction. The oxygen level may be determined by the measurement of voltage and a limiting current of the oxygen depletion electrolyzer cell. The enclosure may be a food or artifact enclosure.

摘要： The disclosure relates in its first aspect to a process of conversion of a gaseous stream comprising methane into hydrogen (51) and carbon (25), the process is remarkable in that it comprises a step (a) of providing a first gaseous stream (3, 7); a step (b) of bromination and synthesis in which the first gaseous stream (3, 7) is put in contact with a second stream (53) comprising bromine resulting in the formation of a third stream (15) comprising methyl bromides and hydrogen bromide, and of a fourth stream (25) comprising carbon including graphite and/or carbon black; a step (c) of separation performed on the third stream (15) to recover a hydrogen bromide-rich stream (41) which is then oxidized in a step (d) to produce a stream (51) comprising hydrogen. The second aspect relates to the installation for performing the process of the first aspect and the third aspect concerns the use of bromine in such process.

摘要： A method for operation of an industrial plant having an energy accumulator unit for production of synthetic natural gas, a power plant unit for production of electricity, an oxygen tank, a carbon dioxide tank and a water tank. In a first operation mode the energy accumulator unit is supplied with excessed electricity from the public grid to produce synthetic natural gas, wherein the produced synthetic natural gas is discharged in a gas network, while oxygen and water which are produced together with the synthetic natural gas are stored in the oxygen tank and the water tank correspondingly. In a second operation mode gas from the gas network together with oxygen from the oxygen tank and water from the water tank are used in the power plant unit to produce electricity, which is supplied to the public grid. This way electricity production excess is efficiently accumulated for industrial or municipal use.
