Abstract:

Single-tube membrane reactor has such disadvantages as difficulty in industrial scale-up，and low efficiency of coupling of reaction and separation. Discrete multi-tube membrane reactor has a compact structure with a larger heat transmission area as in tubular heat exchanger and realizes multi-stage separation as in plate column. In a test of sec-butyl alcohol dehydrogenation system at 150～225 ℃，mole fraction of methyl ethyl ketone reached 94%.
