Effect of pre-treatment on physico-chemical properties and stability of carbo…
Abstract. This paper presents the effects of acid treatment on the activity, product selectivity and life span of iron Fischer–Tropsch (FT) catalysts supported on carbon nanotubes (CNTs). Two different types of CNTs with low surface area (25 m2/g) and high surface area (170 m2/g) were prepared and treated with 35 wt% HNO3 at 25 8C and 110 8C for 16 h. Fe/CNTs were prepared using incipie…

Co, Ru and K loadings effects on the activity and selectivity of carbon nanot…
Abstract An extensive study of Fischer–Tropsch synthesis (FTS) on carbon nanotubes (CNTs) supported cobalt catalysts with different loadings of cobalt, ruthenium and potassium is reported. Up to 30 wt.% of Co, 1 wt.% of Ru and 0.0066 wt.% of K were added to the catalyst by co-impregnation method. The physicochemical properties, activity and selectivity of the catalysts were assessed. For …

Effects of metal content on activity and stability of Ni-Co bimetallic cataly…
Abstract Ni-Co bimetallic catalyst with a general formula of Ni-Co-Al-Mg-O prepared using coprecipitation has shown excellent stability and high activity for CO2 reforming of CH4 in our previous research. This paper focuses on the effects of Ni-Co content of the catalyst, attempting to avoid carbon formation on the catalyst. Catalyst samples with Ni and Co loadings ranging between 1.83 and 14.…

Waste Cooking OilsAn Economical Source for Biodiesel: A Review
Biodiesel (fatty acid methyl ester) is a nontoxic and biodegradable alternative fuel that is obtained from renewable sources. A major hurdle in the commercialization of biodiesel from virgin oil, in comparison to petroleum-based diesel fuel, is its cost of manufacturing, primarily the raw material cost. Used cooking oil is one of the economical sources for biodiesel production. However, the …

Kinetic Studies of Carbon Dioxide Reforming of Methane over Ni-Co/Al-Mg-O Bim…
The kinetics of CO2 reforming with CH4 over a Ni-Co/Al-Mg-O bimetallic catalyst was investigated in a fixed bed reactor at a temperature range of 650-750 °C and the partial pressures of CO2 and CH4 ranging from 30 to 190 kPa. Owing to the simultaneous occurrence of the CO2 reforming reaction and the reverse water-gas shift reaction (RWGS) in the system, the apparent activation energies with…
