摘要： A method of purifying a gas stream derived from a process wherein a glyceride containing raw-material is converted to hydrocarbon paraffins. The gas stream contains hydrogen or carbon dioxide as a major component and at least one sulphurous component selected from sulphide compounds as an impurity. According to the invention, the gas is contacted with an acidic aqueous wash solution of transition metal ions capable of binding to sulphide ions; a significant portion of the sulphide compounds contained in the gas are bound into practically insoluble transition metal sulphide compounds to remove sulphide compounds from the gas to produce a purified gas; and the obtained purified gas is recovered. The method will efficiently lower sulphide concentrations to ppm or sub-ppm level and it can be implemented on an industrial scale with low investment costs. The metal can be recovered.

摘要： A method of purifying gas obtained by gasification of a biomass feedstock. The gas which contains carbon monoxide, carbon dioxide, hydrogen, hydrocarbons and mixtures thereof can be freed from impurities, such as hydrogen sulphide, hydrogen chloride, ammonia, carbonyl sulphide, hydrogen cyanide and mixtures thereof, by contacting the gas with an acidic aqueous wash solution of transition metal ions capable of binding to sulphide ions, by binding a significant portion of the hydrogen sulphide impurities contained in the gas into practically insoluble transition metal sulphide compounds to remove hydrogen sulphide impurities from the gas; and by separating the thus obtained purified gas from the aqueous solution. The purified gas is suitable for production of hydrocarbon compositions by, for example the Fischer-Tropsch process.

摘要： A process for dimerizing light olefinic hydrocarbons in a reaction zone containing a solid acidic catalyst. The process comprises recovering a reaction zone effluent which contains unreacted olefinic hydrocarbons, converting the unreacted olefinic hydrocarbons into an intermediate product in the effluent and separating the intermediate product from the effluent. By decomposing the separated intermediate product the unreacted olefinic hydrocarbons can be recovered and recycled to the reaction zone. By means of the invention, the yield of the product and the lifetime of the catalyst can be improved in a direct dimerization process of light olefins.
