PROCESSES AND SYSTEMS FOR USING SILICA PARTICLES IN FLUID BED REACTOR

The present disclosure relates to fluid bed processes that utilize silica particles as a fluidization aid. The process comprises reacting one or more reactants in a reactor comprising a fluid bed to form a product. The fluid bed comprises a catalyst composition comprising a catalyst and an inert additive composition comprising silica particles from 0.5 wt% to 30 wt%, based on the total weight of the catalyst composition. The silica particles are discrete, inert particles that are mixed with the catalyst in the fluid bed. 本公开涉及使用二氧化硅粒子作为流化助剂的流化床法。所述方法包括使一种或多种反应物在包含流化床的反应器中反应以形成产物。所述流化床包含催化剂组合物，所述催化剂组合物包含催化剂和含有基于催化剂组合物的总重量计0.5重量％至30重量％的二氧化硅粒子的惰性添加剂组合物。所述二氧化硅粒子是在流化床中与催化剂混合的离散惰性粒子。
