摘要： Proposed are a catalyst for decomposing perfluorocompounds (PFCs) and a method of preparing the same. The provided catalyst for decomposing PFCs and the method of preparing the same are as follows. Zinc as an active component for performance improvement and tungsten (W) as an auxiliary component are added to alumina selected from at least one of gamma alumina, aluminum trihydroxide, boehmite, and pseudo-boehmite, and a weight ratio of Al, Zn, and W is at 100:30 to 100:1 to 11. The catalyst for decomposing PFCs not only has an effect of having durability against fluorine generated by decomposition of PFCs but also has a synergistic effect of improving reaction activity. Furthermore, the catalyst decomposes PFCs at a lower temperature than conventional catalysts for decomposing PFCs. Thus, it is possible to reduce operating costs and secure the durability of the system during continuous operation.

摘要： The present invention relates to a method for preparing a dehydrogenation catalyst for a straight chain-type light hydrocarbon using a stabilized active metal composite, in other words, to a dehydrogenating catalyst for C3 to C4 straight chain hydrocarbons, and more specifically, to a technique for preparing a catalyst in which most of metal components contained in the catalyst are distributed evenly in a support in the form of an alloy rather than in the form of each separate metal, thereby exhibiting a high conversion rate and selectivity when used in dehydrogenation.
