Steady-state simulation of Fluid Catalytic Cracking riser reactors using a decoupled solution method with feedback of the cracking reactions on the flow

摘要: Abstract A method is proposed to simulate reactive flow, fully taking into account the effect of reactions on flow. Operator splitting used separate computation convection and reaction. fast solver for mildly stiff ordinary differential equations parallelization reaction term evaluation have been implemented reduce CPU time. The applied steady-state, two-phase gas–solid simulation a Fluid Catalytic Cracking riser reactor. relatively simple kinetic model with four lumped components demonstrate feasibility method. results show that able handle flow significant feedback
