WebThe thermal cracking of n-butane was compared with both thermal and catalytic n-butane oxidative dehydrogenation reactions.It was found that thermal oxidative dehydrogenation of n-butane was highly selective to n-butenes (approximately 70%) in the conversion range of 11–20%.This reaction proceeded at lower temperature than the thermal cracking of n … http://cce.upc.edu.cn/2024/0305/c2673a45576/page.htm
Web31 de jan. de 2010 · Dehydrogenation of n-butane over alumina-supported Pd and Pd–Ga catalysts was studied. Catalysts were prepared by incipient wetness impregnation with a Pd content of 0.66 wt% and atomic Ga/Pd ratios from 0 to ∞, using aqueous solutions of PdCl 2 and Ga(NO 3) 3.Fresh (uncalcined) and calcined catalysts were characterized by X-ray … Web1. The oxidative dehydrogenation of n-butane on metal chlorides in the temperature interval 550–590°C is a heterogeneous catalytic reaction and proceeds when hydrochloric acid is added. 2. Copper, iron, and potassium chlorides, as well as ferric oxide on silica gel, were studied as catalysts for this reaction; the content of the acid ingredient was …
WebNanocarbon materials are promising catalysts of oxidative dehydrogenation (ODH) of alkanes, but improving the alkene selectivity remains a challenge.
