摘要： H2 production, sulfuric acid and SO2 production process refers to an innovative process VIA the phenomena of the Sulfur-Iodine (S-I) thermochemical cycle. The process consist of the acid gas burner to burn all the acid gases with air, enriched air or oxygen and without using any fuel gas to produce SO2. The acid gases are normally processed in the prior arts of the sulfur recovery units. Iodine is used to produce the hydrogen.
A portion or all of the acid gases are sent to the acid gas burner in accordance with the present invention.
The present innovation not only produces hydrogen but also reduces the SO2 and CO2 emissions.
The produced SO2 is sent to other units to produce other fertilizer products and the produced CO2 is sent to CO2 removal or CO2 Liquefaction process.
The hydrogen is produced is used to supply the needs within the facility like hydrotreaters to reduce external import and to reduce the operating costs.

摘要： The present invention relates to a method for the catalytic removal of sulfur dioxide from waste gases in two reactors, wherein the first reactor is charged with an activated carbon catalyst. The method comprises: a. provision of a waste gas with a water content of less than 1 g H2O/Nm3 and an SO2 content of at least 5 ppm, b. introduction of the waste gases into a first reactor, c. catalytic conversion of the SO2 into gaseous SO3 in the first reactor by the activated carbon catalyst, wherein catalytic conversion on the activated carbon catalyst proceeds at a temperature of below 100° C., d. introduction of the prepurified waste gases from the first reactor into a second reactor, e. conversion of the SO3 with water into H2SO4 in the second reactor.

摘要： A non-chrome, copper-containing catalyst, Cu—Al—O and method of preparing the same are provided wherein the Cu—Al—O catalyst is prepared by the co-precipitation of copper nitrate (Cu(NO3)2) and sodium aluminate (Na2Al2O4) solutions using sodium carbonate (Na2CO3) as a precipitant. the precipitate is filtered, washed to remove excess sodium, and dried. The dried product, to be used in a powder form, is calcined at a preferred temperature of approximately 700 to 900° C. for approximately 1 to 4 hours. The dry powder, to be tableted or extruded, is calcined at a temperature of approximately 400 to 700° C. The activity of the Cu—Al—O catalyst can be promoted in hydrogenolysis applications by the addition of various agents. The Cu—Al—O catalyst can be employed in applications in place of Cu/Cr, or other copper-based catalysts.

摘要： A coal or petroleum combustion flue gas containing sulfur oxides and dust is treated by contacting the flue gas with a sulfur dioxide-oxidizing catalyst, thereby converting sulfur dioxide to sulfur trioxide, allowing the resulting sulfur trioxide to react with components of dust, absorbing the trioxide into the dust as a sulfate, and removing the dust. Catalytic oxidation of sulfur dioxide can be efficiently carried out at a low temperature and sulfur oxides can be efficiently removed from the flue gas.
