Definitions
- the present invention relates to a catalyst for producing an olefin having improved selectivity and conversion compared to the prior art, and a method for preparing the same.
- Olefins such as ethylene and propylene are widely used in the petrochemical industry. Generally these olefins are obtained in the pyrolysis process of naphtha. However, the petrochemical industry requires higher amounts of olefins, so olefins are also produced through dehydrogenation processes using catalysts of lower hydrocarbons.
- the main difference between the fixed bed reactor and the fluidized bed reactor is the contact time of the catalyst with the reactants (propane). That is, the fluidized bed reactor is a process in which propane and catalyst are injected together into a fluidized bed reactor at a very high speed, and then the catalyst is returned to the regeneration part and the product is separated into the separation part.
- the goal of the conventionally developed FPDH process is to aim the residence time of the catalyst to less than 10 seconds. If the residence time of the catalyst is short, the propane feed rate is also fast and the catalyst is regenerated and participates in the reaction again. Thus, when developed as a commercial process, the propylene production is greatly increased compared to the fixed bed process.
- the efficiency of the catalyst becomes very important because the contact time between the catalyst and propane is so short. That is, it is important to maximize the two efficiency measures of the catalyst, selectivity and conversion, respectively.
- propane dehydrogenation process technologies currently used are based on noble metal catalysts or discontinuous processes, and even in continuous processes, it is known to be inadequate for the production of millions of tonnes of propylene due to problems in catalyst bed operation.
- propane dehydrogenation is thermodynamically limited by propane conversion due to the reversible reaction of propylene and hydrogen produced. Therefore, for the effective mass production of propylene, it is required to develop a new propane dehydrogenation process that reduces the production cost by solving the problem of the continuous process and using a low-cost non-noble metal catalyst with maximized selectivity and conversion rate.
- the reaction proceeds as a direct dehydrogenation mechanism in which hydrogen is adsorbed to the active site, but in the case of transition metal oxides, the mechanism is clearly identified by the incompleteness of the active site due to electron mobility. This is not true.
- catalysts most commonly used as PDH catalysts are Pt, Pt-Sn, VOx, and CrOx catalysts, and CrOx catalysts are excellent in terms of propane conversion and selectivity.
