Problems solved by technology

However, liquid superacid catalysts have the following disadvantages: severe corrosion of equipment, difficulty in catalyst recovery, and large environmental pollution, while solid superacids have the characteristics of light equipment corrosion, high catalytic selectivity, easy regeneration, no environmental pollution, and easy separation of products.
The solid superacid has a small pore size, and has low catalytic efficiency and is easy to deactivate for larger molecular hydrocarbon raw materials.

Embodiment 1

[0065] Mix 52g of second-line oil and 12g of SP-80, heat to 80°C and mix evenly; heat 375g of aluminum nitrate nonahydrate and 320g of urea to 80°C to melt, drop into the above mixture, and mix for 15 minutes to form a uniform supersolubilized colloid. Seal the reactor and react at 120° C. for 4 hours to obtain nano-aluminum hydroxide gel. Heat 31g of common three-line oil, 7g of minus three-line wax paste, and 6g of polyisobutenyl diethylene glycol maleate to 80°C and mix evenly. 110g of zirconium oxychloride octahydrate is dropped into the above mixture, mix evenly, and keep at 80°C. Then 130 g of ammonia water with a concentration of 40 wt % was added dropwise to obtain a nano zirconium hydroxide gel, which was washed and centrifuged. The nano zirconium hydroxide gel was impregnated with H at a concentration of 0.5 mol / L 2 SO 4 Solution for 0.5 hours, mix well, and dry at 110°C for 12 hours. Mix 20 g of nano aluminum hydroxide dry powder, 60 g of nano zirconium hydroxide...

Abstract

The invention discloses a solid super acidic catalyst and a preparation method thereof. The catalyst has an active ingredient of sulfate radical, and carriers of zirconia and alumina, wherein the carriers are obtained by mixing and forming the zirconia and alumina xerogels prepared by a supersolubilizing micelle method. In the method, the final catalyst has bigger orifices on a big-pore external surface, large pore volume, high porosity, high pore penetrability and high suitability for treating macromolecule-containing reactions, so that the catalyst, different from ink bottle-type orifices, avoids inactivation due to orifice blocking to facilitate the increase of impurity deposition and prolong the running period of the catalyst.

Description

technical field [0001] The present invention relates to a kind of solid superacid catalyst and preparation method thereof, especially SO 4 2- / ZrO 2 -Al 2 o 3 Macroporosity superacid catalyst and preparation method thereof. Background technique [0002] In the past fifty years, only HF and concentrated H 2 SO 4 Production of alkylated oils for the petroleum industry. However, liquid superacid catalysts have the following disadvantages: severe corrosion of equipment, difficulty in catalyst recovery, and large environmental pollution, while solid superacids have the characteristics of light equipment corrosion, high catalytic selectivity, easy regeneration, no environmental pollution, and easy separation of products. However, in the past 30 years, people have paid more and more attention to the pollution and potential safety hazards caused by the use of liquid acid to the environment. Petroleum refiners must spend more financial, material and manpower to monitor and all...
