in this study the catalytic dehydrogenation of ethylbenzene to styrene was investigated in a simulated tubular sodalite membrane reactor. the high quality microporous sodalite membrane was synthesized by direct hydrothermal method and characterized by single gas permeation measurements. the performance of the prepared membrane showed high potential for application in a dehydrogenation membrane ...

Membrane reactors are currently under extensive research and development. Hardly any concept however is realized yet in practice. Frequently, forgotten as membrane reactors are electro-catalyic membrane reactors where electrodes perform chemical conversations and membranes separate the locations of conversion. In this chapter we extensively describe a technology where the membrane itself is cat...

Gas membrane separation technology is a kind of mixed gas with low energy consumption, simple equipment, easy operation and no influence on the environment. Due to special properties graphene oxide (GO) membrane, GO has become research hotspot technology. In this paper, A critical thickness demonstrated: when less than 600nm, conductance inversely exponential thickness, but proportional thicker...

the conditions for the refinement of clarified sugarcane juice, including temperature (50o, 60o and 70oc) and pressure (0, 0.5, 1 and 1.5 bars) by micro-filtration membrane technology were investigated. the raw sugarcane juice was initially pre-filtrated with lime and then the juice obtained (clarified juice) processed using a ceramic micro-filter mem-brane (0.2 micrometer). the characteristics...
