英文摘要：

The preparation of synthesis gas for methanol by the partial shift of purified yellow phosphorus off-gas as feed gas was successfully performed on a pilot-scale shift installation of 40 m^3/h with iron-chromium catalyst in moderate temperature shift. The research results show that the combination of negative pressure and circular heating method by using burned gas of purified yellow phosphorus off-gas is feasible for the heating and deoxidizing of the shift catalyst. The catalyst should be filled in two layers rather than three layers. The synthesis gas can meet the demand of the H2/CO volume flow ratio for methanol synthesis under the technical conditions that the volume flow ratio of steam to gas is 1.35-1.40, the inlet temperature of catalyst bed is 310-320 ℃ and the flow of feed gas is 30-32 m^3/h. The average temperature of catalyst bed rises with the increasing of inlet temperature of catalyst bed, steam flow and feed gas flow. The pilot-scale installation can normally work for at least 130 h and the H2/CO molar ratio of the synthesis gas is 1.87-3.40.
