摘要： The present invention relates to cyclododecanone and a preparation method therefor. According to the present invention, a cyclododecanone preparation method capable of achieving a high conversion rate and minimizing unreacted materials and the production of reaction byproducts can be provided. In addition, the present invention implements a high conversion rate and selectivity despite a simplified process, and thus can be helpfully utilized in economical laurolactam production methods that are easy to mass-produce commercially. According to the present invention, the proportions of cyclododecanol, cyclododecadiol, and the like, obtained as reaction byproducts, in the final product can be drastically reduced, and cyclododecanone can be produced at a high conversion rate.

摘要： Disclosed is a hydrofining catalyst comprising: an inorganic refractory component comprising a first hydrodesulfurization catalytically active component in a mixture with at least one oxide selected from the group consisting of alumina, silica, magnesia, calcium oxide, zirconia and titania; a second hydrodesulfurization catalytically active component; and an organic component comprising a carboxylic acid and optionally an alcohol. The hydrofining catalyst of the present application shows improved performance in the hydrofining of distillate oils. Also disclosed are a hydrofining catalyst system comprising the hydrofining catalyst, a method for preparing the catalyst and catalyst system, and a process for the hydrofining of distillate oils using the catalyst or catalyst system.

摘要： An improved process and catalyst composition for cracking hydrocarbons in a fluidized cracking process are disclosed. The process employs circulating inventory of a regenerated cracking having a minimal carbon content. The regenerated catalyst comprises a catalyst/additive composition which contains a pentasil zeolite, iron oxide, and a phosphorous compound. In accordance with the present disclosure, the catalyst/additive contains controlled amounts of iron oxide which is maintained in an oxidized state by maintaining low amounts of carbon on the regenerated catalyst inventory. In this manner it was discovered that the catalyst composition greatly enhances the production and selectivity of light hydrocarbons, such as propylene.

摘要： A molecular sieve of MFI structure has a ratio of n(SiO2)/n(Al2O3) of more than 15 and less than 70. It has a content of phosphorus of 1-15 wt %, calculated as P2O5 and based on the dry weight of the molecular sieve and a content of the supported metal in the molecular sieve 1-10 wt % based on the oxide of the supported metal and the dry weight of the molecular sieve. The supported metal is one or two selected from lanthanum and cerium. The volume of mesopores in the molecular sieve represents 40-70% by volume of the total pore volume of the molecular sieve by volume, measured by a nitrogen adsorption BET specific surface area method, and the volume of mesopores means the pore volume of the pores having a diameter of more than 2 nm and less than 100 nm.
