What desulfurization method is used to produce methanol from coke oven gas?
Generally divided into wet desulfurization and dry desulfurization; Because of the high content of inorganic sulfur and organic sulfur in coke oven gas, wet and dry desulfurization should be adopted; Wet desulfurization includes low temperature methanol washing, NHD method, etc. Dry desulfurization includes iron-molybdenum catalyst (or nickel-molybdenum catalyst, cobalt-molybdenum catalyst) hydrogenation series zinc oxide (manganese oxide) desulfurization. Theoretically, the conversion of nickel-based catalyst requires that the sulfur content of feed gas be lower than 0.5PPM, 0.1ppm; Used to synthesize copper-based catalyst. In practice, of course, the lower the sulfur content, the better, but usually the first consideration is to maximize economic benefits. Suppliers of low-temperature methanol washing process include Linde, Luqi and Dalian University of Technology in China. NHD method is a technology developed for South China. Northwest Research Institute of Chemical Technology has specially developed JT- 1, JT-8 series coke oven gas dry desulfurization catalysts. View original post >>
