Oslefins and diolefins are important intermediates in the petrochemical industry and the future promises a further substantial increase in demand. While several catalysts have been formulated in the past for the abstraction of hydrogen from butenes and propylene, these catalysts are inefficient in the abstraction of first hydrogen from butane. Bismuth molybdates (β and γ-phases) containing iron oxide and supported on alumina are used as catalysts in the present investigation on the oxidative dehydrogenation of n-butane. Effects of catalyst content, temperature and oxygen: n-butane ratio on conversion and selectivity to butadiene and (C4H8 + C4H6) are studied in the following ranges of experimental conditions: β-bismuth molybdate/100 mol support I(K), 3–9; γ-bismuth molybdate/100 mol support I(K), 5-20; temperature, 400–500°C; O2: butane ratio, 0.6:1.7. 相似文献

To study the photo-grafting performance of acrylamide (AM) onto cellulose and the mechanical behavior of grafted cellulose, Whatman 41 filter paper was grafted with 30% AM in methanol by UV radiation using in situ technique. The amount of grafting (Gf) and tensile properties like tensile strength (TS) and elongation at break (Eb) were studied. In order to improve the tensile properties, cellulose was pretreated under UV and gamma radiations at different radiation intensities and subjected to grafting with 30% AM under in situ UV radiation. Cellulose was also pretreated by alkali (5% NaOH) along with UV and gamma radiations with different intensities and grafted with AM under UV radiation. Among the treatments, the alkali + UV irradiated 30% AM grafted sample showed the best mechanical performance (TS = 200%, Eb = 250%). 相似文献
