    摘要: Method and reactor for performing Fischer-Tropsch (FT) synthesis with controlled steam partial pressure by introducing cool points in the FT reactor, typically in form of cooled solid surfaces. At the surface, the low temperature will force condensation of the water into a liquid film. Thereby, the partial pressure of steam in the gas and reactor will not exceed significantly the vapour partial pressure at the liquid film and water from the gas stream will be removed as it is produced, i.e. steam induced deactivation is avoided. In addition, the decrease of hydrogen and carbon monoxide partial pressures due to dilution by steam will be kept low ensuring a constant high reaction rate.

    摘要: A process for the adjustment of the composition of a synthesis gas produced in a high temperature black liquor gasifier. The process includes the steps of (a) generating a gasifier effluent stream from black liquor in the gasifier by a blast and optionally an atomising stream; (b) optionally quenching the gasifier effluent stream with a gas stream to form a gas quenched effluent stream; (c) quenching the gasifier effluent of step (a) or the gas quenched effluent gas stream of step (b) with a water stream to form a raw synthesis gas; (d) further cooling and cleaning and separating the raw synthesis gas to form a purified unprocessed synthesis gas with an appropriate H2/CO ratio; (e) partly converting the purified synthesis gas to dimethyl ether in a synthesis section, producing at least a product stream of DME and a hydrogen rich purge stream of processed; (f) splitting and recycling individual or combinations of split streams of the processed or the unprocessed synthesis gas to step a and/or step (b); and recycling a by-product stream of CO2 being further generated in step (e) in part or completely to step (a) and/or step (b).
