采用浸渍法制备了V Mg O催化剂 ,利用XRD和BET对催化剂进行了表征 .比较了固定床反应器 (FBR)、惰性膜反应器 (IMR)与混合式惰性膜反应器 (MIMR)用于丁烷氧化脱氢制丁烯和丁二烯反应的性能 .采用在陶瓷膜上部分涂釉的方法获得渗透率符合实验要求的惰性膜 ,利用惰性膜沿反应器轴向分布氧气 ,降低反应区氧气分压 ,从而提高目的产物的选择性 .通过优化进料方式 ,在 2 0MIMR反应器中得到了 6 6 %的C4 烯烃选择性和 33 %的C4 烯烃收率
V Mg O catalysts were prepared by impregnation method and the catalysts were characterized by XRD and BET.The effects of fixed bed reactor (FBR), inert membrane reactor (IMR) and mixed inert membrane reactor (MIMR) Alkane dehydrogenation of butadiene and butadiene reaction performance.Using ceramic coating on the part of the glaze method to obtain the permeability of the film in line with the experimental requirements of the inert membrane along the reactor axial distribution of oxygen to reduce the reaction zone oxygen Partial pressure, thereby enhancing the selectivity of the desired product by optimizing the feed mode, 6 6% C4 olefin selectivity and 33% C4 olefin yield in a 20MIMR reactor
