[ 1 ] - Effect of calcium promoter on nano structure iron catalyst for Fischer–Tropsch synthesis
The Fischer-Tropsch synthesis (FTS) has been recognized as a heterogeneous surface-catalyzed polymerization process. During this process, CHx monomers formed via the hydrogenation of adsorbed CO on transition metals produce hydrocarbons and oxygenates with a broad range of chain lengths and functional groups. A series of Fe/Cu Fischer-Tropsch synthesis catalysts incorporated with a calcium prom...
[ 2 ] - بررسی اثر بهبود دهنده ها و هم افزایی آن ها در نانوکاتالیست کبالت برپایه نانولوله های کربنی جهت کاربرد در واکنش فیشرتروپش
کاتالیست های کبالت بر پایه ی CNT با بهبود دهنده های Ca، Ce،KوZr ساخته شد. سپس افزودن همزمان این بهبود دهنده ها به صورت Ca/Ce وK/Zr با روش تلقیح صورت گرفت و اثر هم افزایی یک بهبود دهنده ی قلیایی، قلیایی خاکی با یک بهبود دهند...
[ 3 ] - Optimizing the vacuum gas oil hydrocracking process temperature in the presence of Ni-Mo/γ-Al2O3-SiO2 catalyst
A suitable model for predicting the product quality of vacuum gas oil (VGO) catalytic hydrocracking is developed. Data were obtained using an experimental catalytic hydrocracking reactor loaded with the Ni-Mo/Al2O3-SiO2 catalyst. A set of experimental runs was conducted under various operating temperatures from 380 to 450 ℃. Three distribution models were used t...
[ 4 ] - The performance of NiMo/SiO2-Al2O3 and NiMo/SO4-Al2O3 catalysts for hydrocracking of n-hexadecane
In this study, the performance of NiMo catalysts over an amorphous SiO2-Al2O3 and SO4-Al2O3 with various contents of H2SO4 was investigated for the n-hexadecane hydrocracking (n-C16) using a down flow fixed bed micro-reactor. The synthesized catalysts were characterized using BET, XRD, and NH...
