Discrete and Multi-tube Pass Number Inorganic Membrane Reactor offers supplements to single-tube membrane reactor, referencing heat exchanger can provide larger transmission area and plate column can realize multi-stage separation. It realizes the reaction and separation occurs simultaneously many times, and can change the membrane area according to the need, so that reaction and separation process can be matched better. Discrete and multi-tube membrane reactor and fixed bed reactor was experimented in sec-butyl alcohol dehydrogenation system at 150-225, the result shows the new membrane reactor structure is reasonable.

Abstract The stage separation of high-speed vehicle is complicated at high dynamic pressure, usually accompanied by strong shock and vortex interaction. There exists a strong interaction between first stage and second stage, which called “afterbody-effects”. The aerodynamic mechanism of “afterbody-effects” is studied in this paper based on numerical simulation. The aerodynamic characteristics of a simplified three-dimensional projectile model at different distances between stages at 0° angle of attack is researched with structural mesh. The results show that the vortexes of stages have a significant impact on the aerodynamic characteristics of different stages, As the distance between stages increases, the drag coefficient of the first stage increases, and the drag coefficient of the second stage increases first and then decreases.
