The invention belongs to the technical field of biomass treatment, and particularly relates to a process for preparing ethylene and co-producing methanol by biomass conversion based on a multi-step coupling microwave reaction. Biomasses such as garden wastes and crop straws are directly converted into a large amount of industrial product ethylene, and methanol is co-produced. According to the process, not only can the solid waste be effectively recycled, but also bulk chemicals can be produced, and the value of biomass such as garden waste and crop straw is improved. 本发明属于生物质处理技术领域，具体涉及一种基于多步耦合微波反应生物质转化制备乙烯联产甲醇工艺，通过将厌氧发酵、微波反应和催化选择性加氢过程有机的耦合起来，实现了将园林废弃物、农作物秸秆等生物质直接转化成大宗工业产品乙烯，并且联产甲醇。上述过程不但可以有效的将固废资源化问题，还可以生产出大宗化学品，提升了园林废弃物、农作物秸秆等生物质的价值。
