Asbestos-derived ZSM-5 and steam-treated ZSM-5 zeolites, as well as ZSM-5 zeolites having a Si/Al atomic ratio ranging from 35 to 55, have been found to be very active and selective in the conversion of aqueous ethanol to ethene at about 300掳C. This was attributed to a moderate ...
A NiSO4/Re2O7/γ-Al2O3 catalyst was prepared by co-impregnation using an aqueous solution of NiSO4 and [NH4][ReO4], which catalyzes direct conversion of ethene to propene at mild reaction condition (323 K, 1 atm). Catalyst deactivation may be caused by coke formation. The two catalyti...
Ethanol is presently the most common liquid fuel derived from biomass. One way of meeting the growing demand for heavier middle-distillate fuels — diesel and jet fuels comprising hydrocarbons of typically 8–22 carbon atoms — is to derive these from ethanol. This Review describes the chemistries...
atalytic conversion of ethanol into 1, 3-butadiene was carried out over ZnO-supported sepiolite. Sepiolite is a fibrous magnesia-silicate clay mineral having intracrystalline channels in which coordinated water molecules and zeolitic water are contained. Magnesium ion along channel wall is coordinated ...
The formation of ethene from ethanol via direct elimination or from diethyl ether as intermediate could be confirmed. In the conversion of ethanol/water mixtures, the product distribution did not change significantly up to a water content of 60 wt%. Then, a pronounced increase of ethene formation...
In addition, the market of bioethanol fuel has shown a dramatic increase and growing at a compound annual growth rate of 7.6% from 2016 to 2022. Bioethanol is a natural type of ethanol made by fermenting the sugar and starch components of plant by-products including sugarcane, corn, and ...
Further dehydration of ethanol with methanol leads to ethyl methyl ether (CH3CH2OCH3) and ethene. Notably, ethene dominates the hydrocarbon products with an ethylene to propylene (E/P) ratio of 5.02 at 473 K, suggesting the MPV pathway as the primary route for hydrocarbon production. This ...
The ever-increasing demand for propene has driven some new strategies to produce propene, such as propane dehydrogenation, metathesis of ethene and 2-butene, catalytic cracking of Calkenes, conversion of methanol and ethanol, and direct ... XU Lulu,Z Zhao,R Zhao,... 被引量: 0发表: 2014年...
