生物基2-甲基呋喃绿色加氢制备2-甲基四氢呋喃工艺研究
Research on the green hydrogenation process of bio-based 2-methylfuran to 2-methyltetrahydrofuran
采用等体积浸渍法制备了2种不同的Pd催化剂,通过一系列表征手段对催化剂的外观形貌和物相结构进行了分析表征。对所制备的催化剂催化活性进行评价,其中以SiO2为载体的Pd/SiO2催化剂表现出更加优异的催化活性,在催化过程中既保证了呋喃环双键的高度氢化,同时避免了呋喃环C—O键和C—C键的过度加氢。在通过对反应条件的优化后,最终实现2-甲基四氢呋喃最高反应收率≥98%。经Aspen模拟后,最终产品纯度达到99%以上,精馏工段的产品收率达到94.5%。
Two different Pd catalysts were prepared using the incipient wetness impregnation method,and their external morphology and phase structure were analyzed and characterized through a series of characterization techniques.The catalytic activity of the prepared catalysts was evaluated,and the Pd/SiO2 catalyst supported on SiO2 exhibited superior catalytic performance.It ensured high hydrogenation of the furan ring double bonds while avoiding over-hydrogenation of the C—O and C—C bonds in the furan ring.By optimizing the reaction conditions,the highest reaction yield of 2-methyltetrahydrofuran reached ≥98%.After Aspen simulation,the final product purity exceeded 99%,and the product yield in the distillation section reached 94.5%.
