DME Synthesis over MSU-S Catalyst through Methanol Dehydration Reaction
MSU-S mesoporous catalyst with [SiO2]/[Al2O3] ratio of 55 was synthesized using tetrapropylammonium hydroxide (TPAOH) as a structure directing agent and hexadecyltrimethylammonium bromide (CTAB) as a surfactant. The catalytic activity of the calcined sample was evaluated for the dehydration of methanol to dimethyl ether (DME) in a vertical fixed bed microreactor...
متن کاملIntrinsic Kinetics of Methanol Dehydration over Al2O3 Catalyst
Dehydration of methanol to dimethyl ether (DME) over a commercial Al2O3 catalyst was studied in an isothermal integral fixed bed reactor. The experiments were performed on the temperature interval 513-613 K, liquid hourly space velocity (LHSV) of 0.9-2.1h, pressures between 0.1 and 1.0 MPa. The effect of different operation conditions on the dehydration of methanol was investigated in a laborat...
متن کاملUse of Pd/Activated Carbon Fiber Catalyst to Dehydrogenate Cyclohexane
Porous carbon materials have attracted growing attention among the different types of supports used in heterogeneous catalysis because of certain favorable characteristics, which are essentially their resistance to acidic/basic media, significant pore and surface tailorability, and ease of recovery of catalytic metals via combustion of the support material. Carbon fibers typically feature a rel...
متن کاملHydrogen generation from hydrolysis of sodium borohydride using sulfonated porous carbon as reagent/catalyst
The hydrolysis of sodium borohydride as a source of hydrogen gas is studied at different mole ratios of H+ to NaBH4. The sulfonated porous carbon (SPC) is used as a source of hydrogen ion and catalyst. It is found that the sulfonated porous carbon exhibits high activity for the hydrolysis of NaBH4 to generate hydrogen gas at room temperature in comparison to Amberlyst-15 and Nafion-NR50. The ki...
متن کاملSelective catalytic reduction of sulfur dioxide by carbon monoxide over iron oxide supported on activated carbon
The selective reduction of sulfur dioxide with carbon monoxide to elemental sulfur was studied over ACsupported transition-metal oxide catalysts. According to the study, Fe2O3 /AC was the most active catalyst among the 4 AC-supported catalysts tested. By using Fe2O3 /AC, the best catalyst, when the feed conditions were properly optimized (CO/SO2 molar ratio = 2:1; sulfidation temperature, 400 ◦...
