Embodiment 1

[0027] Install a stirring blade in the middle port of the three-necked glass bottle, and install a thermometer and a condenser tube in the other two ports. 3gTiCl 4 and 3g of gelatin were dissolved in 100g of water; the monomer phase was composed of 10g of styrene and 1g of divinylbenzene, adding initiator benzoyl peroxide 0.03g and porogen isooctane 5g and stirring until completely mixed; After the bulk phase was stirred at 1000r / min for 2 hours, the temperature began to rise. First, the polymerization temperature was raised to 60°C. After 3 hours of reaction, the temperature was gradually raised to 90°C. The heating process lasted for 10 hours. The formed particles were washed several times with hot deionized water and dried at 80°C.

[0028] Sulfonate with 100% concentrated sulfuric acid, carry out sulfonation in a three-necked flask at 90°C for 10 hours, gradually wash with water until the eluate is neutral, and obtain the finished product. Dry at 80°C for use.

Abstract

The invention discloses a superposition reaction method for lower carbon number olefin, which comprises: on reaction condition as 50~180Deg, 0.5~3.0MPa pressure and 0.5~6.0h-1 feeding weight air speed, contacting the superposition reaction material with a sulfonated composite material catalyst; wherein, the composite material comprises inorganic oxide with element selected from one or more of IIIB group, IVB group, VB group, VIB group, VIIB group, VIII group, IB group, IIB group, IIIA group, IVA group, and VA group; and organic resin polymerized by styrene monomer and divinylbenzene. This method has more wide reaction temperature and longer stable running time.

Description

technical field [0001] The present invention relates to a stacking reaction method, and more specifically relates to a low-carbon olefin stacking reaction method carried out in the presence of a composite material catalyst of an inorganic oxide and an organic resin. Background technique [0002] The superposition reaction of isomeric carbon tetraolefins is one of the important ways to produce high-octane blending components. In recent years, due to increasingly stringent environmental protection regulations, the restrictions on olefins and aromatics in gasoline have become increasingly strict, and the market's demand for high-grade gasoline has also increased with the development of the automobile market. Therefore, the C4 alkene superposition process has also become more important. [0003] The traditional C4 alkene stacking process uses a large number of macroporous cation exchange resins as catalysts. Generally, macroporous cation exchange resins have good catalytic act...
