The present study focuses on the catalytic conversion of syngas (CO + H 2 ) through Fischer–Tropsch (FT) route using two identically prepared 0.1 wt.% palladium promoted Mesoporous Alumina (MA) and SBA–15 supported Co (15 wt.%) catalysts. activity is performed in a fixed bed tubular reactor at temperature 220 °C pressure 30 bar with /CO ratio ~2 having Gas Hourly Space Velocity (GHSV) 500 h −1 ...

سنتز فیشر-تروپش نقش مهمی در تولید سوخت های مایع، مواد شیمیایی و سایر محصولات هیدروکربنی دارد. این کار، یک مدل جدید را برای رآکتور سنتز فیشر-تروپش ارائه می دهد که در آن زئولیت 4a با ترکیب na12(si12al12o48).27h2o به عنوان جاذب آب در نظر گرفته شده است. برای این منظور، یک رآکتور گاز-جامد متحرک-بستر ثابت به جای رآکتورهای مرسوم بستر ثابت مورد استفاده قرار گرفته است. مزیت اصلی این رآکتور گاز-جامد متحر...

Context. How simple organic matter appeared on Earth and the processes by which it transformed into more evolved compounds, ultimately led to emergence of life, is still an open topic. Different scenarios have been proposed, main one assumes that compounds were synthesized, either in gas phase or surfaces dust grains, during process star formation they incorporated larger bodies protoplanetary ...

in a novel dual bed reactor fischer-tropsch synthesis was studied by using two diffrent cobalt catalysts. an alkali-promoted cobalt catalyst was used in the first bed of a fixed-bed reactor followed by a rutenuim promoted cobalt catalyst in the second bed. the activity, product selectivity and accelerated deactivation of the system were assessed and compared with a conventional single bed react...

The gasification of biomass is a promising technique to generate different forms of valuable alternative energy, including direct thermal energy and further conversion of synthesis gas to clean liquid fuels or chemicals via Fischer– Tropsch synthesis (FTS) [1–5]. The ideal H2/CO ratio for FTS is ~2/1 based on the stoichiometry. However, The H2/ CO for the synthesis gas obtained from biomass gas...
