  • Patent number: 11905478
    Abstract: A process for the manufacture of a useful product from carbonaceous feedstock of fluctuating compositional characteristics, the process comprising the steps of: continuously providing the carbonaceous feedstock of fluctuating compositional characteristics to a gasification zone; gasifying the carbonaceous feedstock in the gasification zone to obtain raw synthesis gas; sequentially removing ammoniacal, sulphurous and carbon dioxide impurities from the raw synthesis gas to form desulphurised gas and recovering carbon dioxide in substantially pure form; converting at least a portion of the desulphurised synthesis gas to a useful product. Despite having selected a more energy intensive sub-process i.e. physical absorption for removal of acid gas impurities, the overall power requirement of the facility is lower on account of lower steam requirements and thereby leading to a decrease in the carbon intensity score for the facility.

  • Patent number: 11891344
    Abstract: The present disclosure discloses a method for graded utilization of fluorine and silicon resources in a phosphate ore. While the phosphate ore reacts with sulfuric acid, a fluorine-containing and silicon-containing tail gas is produced. SiO2 and H2SiF6 solution with a high concentration are obtained by concentrating and filtering a solution containing HF and H2SiF6 formed after tail gas is absorbed by water. Crude SiF4 and a solution containing HF and H2SO4 are obtained by extracting, adsorbing, and dehydrating the H2SiF6 solution. SiF4 with a 5N purity is obtained after the crude SiF4 is adsorbed and distilled, at the same time, an impurity-enriched SiF4 is returned to operations of concentration and filtration to react with the solution containing HF and H2SiF6 to generate the H2SiF6 and SiO2. High-purity HF and waste sulfuric acid are obtained after the H2SO4 solution containing HF is separated by steam stripping and distillation.

  • Patent number: 11879099
    Abstract: A Fischer-Tropsch (FT) process with a hybrid membrane/PSA configuration provides high component recoveries from FT off gas with minimum power consumption. Synthesis gas from a synthesis gas production zone is reacted in an FT reaction zone forming a liquid stream and an off gas stream. The off gas from the FT reaction zone, which contains hydrogen, carbon monoxide, and methane reactants, is recycled to the synthesis gas production zone. A purge stream from the recycle loop is sent to a membrane separation unit where it is separated into a permeate stream and a residue stream. The residue stream is separated in a pressure swing adsorption (PSA) unit into a fuel gas stream and a second stream. The second stream can be compressed and recycled to the synthesis gas production zone.

  • Patent number: 11858890
    Abstract: A novel process can be used for a heterogeneously catalysed oxidation reaction, in the presence of a pulverulent noble metal-containing catalyst, where (meth)acrolein, an alkyl alcohol, in particular methanol, and an oxygen-containing gas are converted to an alkyl (meth)acrylate, in particular methyl (meth)acrylate. A corresponding reactor suitable for performing the reaction is also useful. The process allows for an effective retention of the particulate catalyst and the continuous discharge of fines fractions of the catalyst powder which are present, particularly in a fresh catalyst batch as a consequence of its preparation. Such fines fractions may also be produced by abrasion during the reaction. The process allows for effective recycling, recovery, and utilization of these discharged catalyst fractions.

  • Patent number: 11859135
    Abstract: Production of fuels from low carbon electricity and from carbon dioxide by the use of a solid oxide electrolysis cell (SOEC) and Fischer-Tropsch is shown. Fischer-Tropsch is an exothermic reaction that can be used to produce steam. Steam produced from the Liquid Fuel Production (LFP) reactor system, where the Fischer-Tropsch reaction occurs, is used as feed to the SOEC. The higher temperature steam improves the efficiency of the overall electrolysis system. The integration of the LFP steam improves the efficiency of the electrolysis because the heat of vaporization for the liquid water does not have to be supplied by the electrolyzer.
