multi objective optimization of propane ammoxidation reactor to boost acrylonitrile and acetonitrile

In this paper, the multi optimization of propane ammoxidation in a conventional tubular reactor (ctr) is investigated the propane ammoxidation is an exothermic process which is performed in six parallel reactions of formation (propylene, acrylonitrile, carbon oxides, acetonitrile, hydrogen cyanide, and 𝐶2 hydrocarbons), three reactions of consecutive of the transformation of the intermediate propylene to acrylonitrile (acn), acetonitrile (accn), and hydrogen cyanide (hcn), five decomposition reactions of intermediate products to carbon oxides, and one reaction of decomposition of ammonia langmuir-hinshelwood approach is developed in reactions on v-sb-al based mixed oxide catalyst the process is proposed to take place in tubular reactor in the temperature range of (680-810 k) and pressure range of (05-2 bar) the multi-optimization is applied to enhance the molar flow rate of acrylonitrile(acn) and decline the molar flow rate of co, and 2co
