摘要： This invention relates to a method of preparing a multicomponent bismuth molybdate catalyst by changing the pH of a coprecipitation solution upon coprecipitation and a method of preparing 1,3-butadiene using the catalyst. The multicomponent bismuth molybdate catalyst, coprecipitated using a solution having an adjusted pH, the preparation method thereof, and the method of preparing 1,3-butadiene through oxidative dehydrogenation using a C4 mixture including n-butene and n-butane as a reactant are provided. The C4 raffinate, containing many impurities, is directly used as a reactant without an additional process for separating n-butane or extracting n-butene, thus obtaining 1,3-butadiene at high yield. The activity of the multicomponent bismuth molybdate catalyst can be simply increased through precise pH adjustment upon coprecipitation, which is not disclosed in the conventional techniques. This method can be applied to the increase in the activity of multicomponent bismuth molybdate catalysts reported in the art.

摘要： A process for producing cyclopentane from by-product streams containing cyclopentene consists of distilling the cyclopentene from the feedstream and then hydrotreating the cyclopentene-containing fraction to cyclopentane. A second distillation step may then be employed to remove the hydrocarbons which are lighter than cyclopentane. The process has particular applicability in the treatment of feedstreams containing neo-hexane. The cyclopentene is easily separated from the neo-hexane in a conventional fractionator.

摘要： Disclosed is a process for completely destroying oxygenates in a feed stream. The feed stream of oxygenates typically includes olefins and it is reacted with hydrogen over a catalyst comprising a top row of Group VIII metal and a Group VI-B metal. Olefins are essentially completely saturated and any sulfur compounds present in the feed are completely converted to hydrogen sulfide. A preferred catalyst includes 2 to 5 wt-% nickel, 5 to 15 wt-% molybdenum, at least 5.5 wt-% sulfur, less than 0.05 wt-% phosphorus and no more than 0.3 wt-% silicon. The catalyst has low acidity and therefore does not promote the cracking of desired oligomeric products. The deoxygenation process is preferably a saturation process that follows an oligomerization process in which light olefins are oligomerized to heavy olefins. The saturation catalyst preferably has lower acidity which causes minimal cracking of desired oligomeric products. However, by optimally raising the temperature of the outlet of the saturation reaction zone, excessively heavy oligomers can be cracked down to desirable heavy oligomers.
