SILICONE1200 is an inexpensive domestic poly (dimethylsiloxane)-based sealer that was used in this study to remove volatile organic compounds from over-saturated water using the pervaporation technique. A series of liquid representing important part polluting products released every day were chosen for study. These alkyl halides (chloroform), aromatics (toluene), aliphatic hydrocarbons (heptane...

Styrene is an important monomer in the manufacture of thermoplastic. Most of it is produced by the catalytic dehydrogenation of ethylbenzene. In this process that depends on reversible reactions, the yield is usually limited by the establishment of thermodynamic equilibrium in the reactor. The styrene yield can be increased by using a hybrid process, with reaction and separation simultaneously....

Tubular supported carbon molecular sieve membranes (CMSMs) with high hydrophilicity and perm-selectivities for water suitable ethanol dehydration were developed from a Novolac oligomer phenolic resin as precursor. Alpha alumina CMSMs resulted in 1.69 times higher surface roughness than zirconia supports. The 48% selective layer thickness. According to pervaporation results, permeance decreased ...

Functionalized and reduced graphene oxide nanosheets with octadecylamine (rGOODA) were incorporated in polydimethylsiloxane (PDMS) membranes to be used pervaporation for removal of toluene from water. The properties the functionalized characterized by FTIR, XRD, Raman, SEM, TGA analyses. prepared mixed matrix (MMMs) using contact angle, AFM, SEM-EDX, TGA, solvent uptake tests. contained (rGO) r...

Development of a catalytic membrane reactor concept and investigation its performance by CFD simulations.

Membrane methods are environmentally friendly and can significantly improve the design development of new energy consumption processes that very important nowadays. However, their effective use requires advanced membrane materials. This study aims to performance pervaporation polyvinyl alcohol (PVA)-based for isopropanol dehydration. To achieve this goal, two were applied: (1) bulk modification...

• Research, develop and demonstrate the Ion Transport Membrane (ITM) Syngas ceramic membrane reactor system for the low-cost conversion of natural gas to hydrogen and synthesis gas. • Scale-up the ITM Syngas reactor technology through three levels of pilot-scale testing and precommercial demonstration. • Obtain the technical, engineering, operating and economic data necessary for the final step...
