C5/C6 olefin polymerization catalysis technology method of light gasoline

Abstract

The invention provides a C5 / C6 olefin polymerization catalysis technology method of light gasoline. The C5 / C6 olefin polymerization catalysis technology method comprises the following steps of fillinga strong acid type cation resin catalyst into a fixed bed reactor; sending light gasoline containing C5 / C6 olefins into the fixed bed reactor via the top part, and discharging a reaction product outof the fixed bed reactor via the lower part, wherein the reaction pressure in the fixed bed reactor is 1.0 to 1.5MPa, the air speed is 0.5 to 2h<-1>, and the reaction temperature is 60 to 90 DEG C. The strong acid type cation resin catalyst is prepared by the following steps of suspending and copolymerizing styrene and divinyl benzene monomers under the actions of a pore forming agent and a surfactant containing triethanolamine soap, sulfated castor oil, sodium lauryl sulfate and sodium glycocholate, so as to obtain a copolymer white ball; purifying by pores, and sulfonating. By adopting the technical scheme, the strong acid type cation resin catalyst has high-efficiency activity and stability in the C5 / C6 olefin polymerization catalysis technology method of the light gasoline.

Description

technical field [0001] This patent application relates to a superposition process of olefins in light gasoline, in particular to a superposition process of catalytic cracking of olefins in light gasoline. Background technique [0002] In September 2017, the State Administration of Quality Supervision and the Standardization Management Committee issued and simultaneously implemented the two standards of GB 18351-2017 "Ethanol Gasoline for Vehicles (E10)" and GB 22030-2017 "Ethanol Gasoline Blending Component Oil for Vehicles". 15 ministries and commissions including the National Development and Reform Commission jointly issued a notice on the "Implementation Plan for Expanding the Production of Biofuel Ethanol and Promoting the Use of Ethanol Gasoline for Vehicles", confirming that the use of ethanol gasoline will be promoted in many provinces and cities such as the Northeast from 2017, and it is planned that by 2020, the national Basically achieve full coverage. Although fu...

Problems solved by technology

Although fuel ethanol, MTBE and TAME are all oxygen-containing gasoline cleaning additives, the latest standards require that other oxygen-containing compounds must not be artificially added to ethanol gasoline. Therefore, etherified components such as MTBE and TAME will not As gasoline blending components, light gasoline C5 / C6 olefins are facing new application and utilization bottleneck technical problems
