【Abstract】 This paper presents the results of experiments on the optimum distribu-tion of gaseous products in a fast fluidized bed with diameter 2.6 cm for oxyde-hydrogenation of butene to butadiene.The reaction conditions were as follows:H-198 industrial catalyst with an average diameter of d_p=88μm,butene purity92.64%,reaction temperature 330—380℃,space velocity 298—328h^-1,mole ratiowater to butene 7.5—8.3:1,mole ratio oxygen to butene 0.94—0.97:1,linear vel-ocity 460—490cm/s.Our conclusion is that conversion of butene and yield of bu-tadiene are 15—25% higher than that in the baffled fluidized bed.The resultsobtained are used for determining the dimension of the reactor,更多还原
