Other AbstractThe invention relates to a catalyst used for preparing 1,3-propylene glycol through glycerin hydrogenolysis, and specifically relates to a preparation method and an application of a mesoporous-tungsten oxide-supported platinum-based catalyst. According to the invention, mesoporous tungsten oxide is adopted as a carrier, and active components such as metal platinum or other noble metals are highly dispersed on the surface of the carrier, wherein the theoretical content of the active components accounts for 0.1-40% of the mass of the carrier. The catalyst is characterized by good selectivity and high activity. With the catalyst, high-selectivity preparation of 1,3-propylene glycol can be realized through glycerin hydrogenolysis under hydrothermal conditions comprising a temperature of 120-300 DEG C and a hydrogen pressure of 0.1-15MPa. | 本发明涉及一种甘油氢解制备1,3-丙二醇的催化剂,具体地说是一种介孔氧化钨担载的铂基催化剂的制备和应用。以介孔氧化钨为载体,活性组分金属铂或其他贵金属高分散于载体表面,其中活性组分的理论含量为载体质量的0.1-40%。催化剂具有选择性好、活性高的特点,它能够在120-300°C、0.1-15MPa氢气压力的水热条件下实现甘油氢解高选择制备1,3-丙二醇。
