Analysis of the Fixed Bed Reactor for DME Synthesis

DME is considered as one of the most promising candidates for the substitute of LPG and diesel fuel. We analyzed one-step DME synthesis from sysngas in a fixed bed reactor with consideration of the heat and mass transfer between catalyst pellet and reactants gas and effectiveness factor of catalysts together with reactor cooling through reactor wall. Simulation results show effects of pore diffusion, arrangement of catalysts and heat transfer on the performance of the reactor
