With the large consumption of fossil fuels and the gradual rise of the "low-carbon" revolution worldwide, the use of biomass renewable resources to prepare fuels and chemicals has become a general trend, and has attracted the increasing attention of scientists in related research fields. Biomass is a renewable carbon resource, which is rich in sources and can be converted into various liquid fuels. Therefore, the development of biomass energy is of great significance to replace traditional fossil fuels. In China, crop straw is one of the most common biomass renewable resources. In the past, it was often discarded as waste or burned as low-grade fuel with low utilization rate. In order to reduce production cost and achieve sustainable development, the common biomass corn straw was used as raw material to produce acetylpropionic acid (LA). Traditionally, inorganic acids have been used as catalysts to prepare LA. Although inorganic acid as catalyst can also achieve considerable yield, there are still some problems: 1) Difficulty in acid recovery, waste water discharged in the preparation process can cause environmental pollution; 2) High acid concentration requires high requirements on the equipment, in order to increase the corrosion resistance of the equipment will increase the production cost. In order to solve these problems, solid acid catalysts attract researchers’ attentions. Among them, mesoporous HY is an effective solid acid to prepare LA, which has attracted extensive attention. Modification is also a feasible method, and in this paper, we introduced a novel process to modify it to prepare high yield LA.
