It covers the 18 year period from the early eighties, when laboratory scale preparations and micro-reactors were heavily used, right through to the present day with the commercial scale manufacture and proving of the finished catalyst in BP's new ＄86 million gas to liquids demonstration facility in Nikiski, Alaska. Extensive performance testing and scale-up experiments have been successfully carried out, all proof that a laboratory preparation can indeed be translated into a commercial manufacturing process. In addition, the resulting catalyst does not only meet the process design targets, but also exhibits enhanced stability and is tolerant to carbon dioxide. Above all, a commercial scale, fixed bed Fischer-Tropsch catalyst is now available and ready for licensing. Manufacturing procedures and quality control have all been successfully detailed and transferred to the commercial manufacturer.展开更多

In the present study, we have modified cobalt based Fischer-Tropsch catalyst and developed a process to minimize methane production, consequently to produce maximum yield of light olefins. Manganese-cobalt oxide supported on H-5A zeolite catalyst was synthesized using modified H-5A zeolite, to increase its surface acid sites. Increased acidity of zeolite plays a major part in the suppression of methane formation during the Fischer-Tropsch reaction. The modified zeolite results in the electronic modification of catalyst surface by creating new active catalytic sites. The results are compared with other supported catalysts along with unmodified zeolite. Appreciable reduction in methane formation is achieved on modified zeolite supported catalyst in comparison with unsupported catalyst.展开更多

The separation scheme consists of three steps： （1） the raw material is pre-separated by fractional distillation into four fractions according to normal boiling points; （2） appropriate extractants are selected to sep- arate the primary alcohols from the saturated alkanes in each fraction; （3） the extractants are recovered by azeotropic distillation and the primary alcohols in the extract phase are purified. Based on the proposed method, the total recovery rates of the primary alcohols and the saturated alkanes are 86.23% and 84.62% respectively. 2014 The Chemical Industry and Engineering Society of China, and Chemical Industry Press.
