MFI zeolite membranes, especially b-oriented ones, show superb vapor permeation/separation performance for xylene isomer separation at low pressures. In industrial applications these membranes should be operated high pressures in the mode or with liquid feed pervaporation mode. This paper reports influence of activity on and membranes. High quality were synthesized an organic template modified ...

Although a number of gas-phase chemical mechanisms, such as CBM-IV, RADM2, and SAPRC have been successful in studying gas-phase atmospheric chemical processes, they all used different combinations of lumped organic species to describe the role of organics in gas-phase chemical processes. Photochemical Assessment Monitoring Stations (PAMS) have been in use for over a decade and yet it is not cle...

Deep-UV absorption spectrometry for detection of toxic airborne gases, instance, Benzene, Toluene, Ethylbenzene, and Xylenes (BTEX) has drawn considerable attention owing to its high sensitivity reliability. However, the development a deep-UV absorbance detector having good sensitivity, portability, low-volume gas cell with applicability micro Gas Chromatography (μGC) is challenging. Herein we ...

Abstract The study investigated the emissions of volatile organic compounds (VOCs) from a mining soil amended with sewage sludge and irrigated wastewater or without tomato plants. aim is to find out whether amendment irrigation change VOC changes compared uncultivated soil. Soil plant experiments were done in assembled pots. All pots placed inside closed glass chamber an isolated windowless roo...

A highly sensitive and selective silicon-based microanalytical prototype was used to identify a few ppb of volatile organic compounds (VOCs) in indoor air. Herein, new nonactivated tannin-derived carbon synthesized by an environmentally friendly method, DM2C, MIL-101(Cr) MOF, DaY zeolite were selected for the preconcentration BTEX (i.e., benzene, toluene, ethylbenzene, xylenes). Integrating sma...

The catalytic co-conversion of glycerol and oleic acid (45/55 wt%) to bio-based aromatics (benzene, toluene, xylenes, bio-BTX) over a technical H-ZSM-5/Al2O3 catalyst in fixed-bed reactor was investigated with special attention deactivation phenomena. spent catalysts after time on stream (TOS) 12 h were regenerated by an ex-situ oxidative treatment remove coke reused for another run. In total, ...
