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 ...

In this paper, a system for efficient removal of carbon dioxide by hollow fiber membranes is proposed. The system is compact, and it is very useful for application in the offshore energy industries. In particular, it is used to removing CO2 from the exhaust of power generation facilities on offshore platforms.The proposed dual membrane contactor contains two types of membranes (polypropylene me...

Membrane bioreactor (MBR) is an efficient wastewater treatment technology, which produced by combining membrane technology and biological has the characteristics of stable water quality shock load resistance, been widely used in domestic treatment. Anaerobic ammonia oxidation (ANAMMOX) a new type denitrification with advantages low energy consumption, oxygen demand, carbon source saving good ec...

Versatile Filter Transfer Method for Carbon-Nanotube Thin Films In article number 2100953, Manabu Ishizaki, Masato Kurihara, and co-workers develop a solution-processed press-free transfer method of carbon-nanotube (CNT) thin films onto arbitrary materials by using polytetrafluoroethylene membrane filters. Topically, CNT can be transferred solvent-sensitive perovskite (CH3NH3PbI3) layer as top-...

Zeolites are crystalline microporous materials with well-defined and uniform pore structure that find extensive industrial uses as adsorbents, catalysts and ion exchangers [1-2]. Zeolite films supported on different materials have been successfully prepared and have potential applications as highly selective membrane separators, membrane reactors, chemical sensor and microdevices [3-10]. Most o...
