The invention discloses a catalyst for hydrogen production by methanol steam cracking and a corresponding hydrogen production method. According to the catalyst, 50-90 parts of CuO, 5-80 parts of ZnO,3-12 parts of La2O3, 20-30 parts of Al2O3 and rare earth elements are used as the catalyst, a mixture of water and methanol is gasified and then cracked in a cracking chamber under the catalysis of the catalyst to produce hydrogen, the temperature of the cracking chamber is controlled to be 300-500 DEG C, and the molar ratio of water to methanol is 1-1.5: 1. Finally, the conversion rate of methanol can reach 96%, and the hydrogen yield can reach 85%.
Description
technical field [0001] The invention belongs to the field of hydrogen production, and relates to a catalyst and a hydrogen production method for hydrogen production by steam cracking of methanol. Background technique [0002] In recent years, with the rapid development of industry, the environmental pollution has become increasingly serious, and the pressure on environmental protection is increasing. There is an urgent need for new clean energy to replace the current conventional energy "coal". my country is a country with more coal and less oil and gas. At present, there are more and more enterprises producing methanol from coal chemical industry, and the desire to use methanol as a conventional energy source is very urgent; Calorific value and range of use. At present, there is no efficient catalyst for hydrogen production from methanol water vapor. Contents of the invention [0003] The object of the present invention is to provide a catalyst for methanol steam cracking...
