Patent number: 11891344Abstract: 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.Type: GrantFiled: April 5, 2023Date of Patent: February 6, 2024Assignee: CHTEM LIMITEDInventor: Xiaowei Quan

Patent number: 11879099Abstract: 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.

Patent number: 11859135Abstract: 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.Type: GrantFiled: March 2, 2023Date of Patent: January 2, 2024Assignee: Infinium Technology, LLCInventors: Robert Schuetzle, Dennis Schuetzle, Anja Rumplecker Galloway, James Bucher
