摘要：Circular and branched pipe distributors were designed for Fischer-Tropsch synthesis in a fluidized-bed reactor. A numerical investigation of the effects of these distributors on product selectivity and production rate was performed. Under the same conditions, the circular distributor gave higher production rates for small diameter particles. For superficial gas velocities ranging from 5 to 15 times the minimum fluidization velocity, the production rates of methane and C5+(the sum of C10H22 and C22H46)were 18%, which was 2% higher than those using the branched pipe distributor, while the C5+ selectivity was 1% lower. For deeper beds, the circular distributor led to higher production rates and the selectivity for C5+ was 5% lower than that using the branched pipe distributor.
