a series of x(co, mn)/tio2 catalysts (x=2–12wt.%) containing 25%co and 75%mn were prepared by the co-impregnation method. all prepared catalysts have been tested in fischer-tropsch synthesis for production of c2-c4 olefins. it was found that the catalyst containing 8wt.%(co,mn)/tio2 is an optimal catalyst for production of c2-c4 olefins. the effect of operation conditions such as the h2/co mola...

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 ...

The unique catalytic activity of vanadium nitrogenase suggests a new direction for the direct production of biofuels from CO with either synthetic catalysts or nitrogenase-containing bacteria. The reduction of CO by V nitrogenase to light hydrocarbons shows striking similarities to the established Fischer-Tropsch process; however, the enzyme does not use H(2) directly for this reaction. ADP=ade...

The discovery of the catalytic synthesis of ammonia must rank as one of the important discoveries by mankind. In addition to providing the fertilizer needed to feed an expanding population, Fritz Haber’s recognition of recycle processing combined with the developing German technology to handle high pressures of hydrogen, led a major revolution in the chemical industry. In rapid succession, the ...

The determination of the catalyst’s active phase helps improve catalytic performance Fischer–Tropsch (FT) synthesis. Different phases cobalt, including cobalt oxide, carbide, and metal, exist during reaction. content each can affect product distribution. In this study, a series carbide catalysts were synthesized by exposure Co/Al2O3 catalyst to CH4 at different temperatures from 300 °C 800 °C. ...

Hierarchical structured α-Al2O3 is shown to be able to effectively disperse and immobilize iron species, in comparison with commercial α-Al2O3. After promotion using an appropriate amount of sulfur, iron catalysts exhibit not only enhanced Fischer-Tropsch synthesis activity and selectivity toward lower olefins, but also increased resistance against carbon deposits.
