The invention discloses an ion exchange resin catalyst for hydrogen production by methanol conversion and relates to the technical filed of petrochemical industry. Modified cation exchange resin is taken as a matrix, and copper is taken as a metal element modifier, and the ion exchange resin catalyst is prepared through a second-order up-temperature impregnation method and a microwave treatment method; the copper in the prepared catalyst occupies 0.5-3 percent of the mass of the catalyst. By using the catalyst for the first time, the catalytic efficiency reaches 55 percent or above, the recycling rate reaches 80 percent or above, and the catalytic efficiency after regeneration still can reach 40 percent or above; a copper element is adopted as catalytic metal, so that the purchasing cost of precious metal is reduced, and the recycling of the catalyst is more conducive to environment protection. 本发明公开了种甲醇转化制氢用离子交换树脂催化剂，涉及石油化工技术领域，以改性阳离子交换树脂为基体，以铜为金属元素改性剂，通过二阶升温浸渍法和微波处理法制得，所制催化剂中铜占催化剂质量的0.5-3％。本发明催化剂的首次使用催化效率达到
