摘要:The present invention relates to novel heterogeneous catalyst composition for selective synthesis of Nabumetone in one pot process and process to prepare the catalyst. The present invention provides a novel catalyst comprises of Lanthanum, Magnesium, and Nickel particles doped on specific type of silica support, preferably that the support is in amorphous nature. The catalyst is having bifunctional condensation and hydrogenation properties for one pot synthesis of Nabumetone comprising of: Nickel and Lanthanum-magnesium mixed oxide on support of mesoporous silica; Wherein 25 to 30 % w/w of Lanthanum-magnesium mixed oxide are entrapped in pores and surface of support is coated with 3 to 5% w/w Nickel with the result that it prevent the leaching of Lanthanum-magnesium mixed oxide in reaction medium and provides reusability of catalyst.

摘要:The present invention relates to a mesoporous cobalt-metal oxide catalyst for the Fischer-Tropsch synthesis and a method of preparing the same. The mesoporous cobalt-metal oxide catalyst for the Fischer-Tropsch synthesis of the present invention can very stably maintain the mesoporous structure even under a H2-rich high-temperature reduction condition and under a reaction condition of the low-temperature Fischer-Tropsch synthesis, easily transport reactants to the active site of the catalyst due to structural stability, and facilitate the release of heavier hydrocarbon products after production thereof. Additionally, unlike the conventional cobalt-based catalysts which are prepared by adding various co-catalysts for the purpose of improving reducibility, activity, selectivity and increasing thermal stability, etc., the mesoporous cobalt-metal oxide catalyst for the Fischer-Tropsch synthesis can constantly maintain conversion and selectivity at high levels without further requiring co-catalysts and thus it can be very effectively used for the Fischer-Tropsch synthesis.

摘要:High surface area, high entropy oxides comprising multiple metal cations in a single-phase fluorite lattice material enables intrinsic catalytic activity without platinum group metals, tunable oxygen storage capacity, and thermal stability. These properties can be obtained through a facile sol-gel synthesis to provide a low-temperature route for production of phase-pure multi-cationic oxides. The resulting materials achieved significantly higher surface area and catalytic performance, taking advantage of all the properties endowed by the various cations in the composition.
