Abstract: Provided are an in situ bifunctional catalyst for deep desulfurization and increasing octane number of gasoline, and its preparation method and application. The bifunctional catalyst includes a modified catalyst carrier and a loaded active metal, where the modified catalyst carrier is a composite carrier prepared through mixing γ-Al2O3 and an acidic molecular sieve by a binder and calcining. When the bifunctional catalyst provided by the present application is used for hydrodesulfurization of gasolines, deep desulfurization, olefin reduction and octane number preservation can be realized simultaneously, thereby obtaining a high-quality oil product.

Abstract: The present disclosure provides a composite ionic liquid and a preparation method and a use thereof. A first aspect of the present disclosure provides a preparation method of a composite ionic liquid, where an ammonium salt, a first metal salt, a second metal salt, and a third metal salt are sequentially added into a reactor for performing a reaction under different conditions, and the composite ionic liquid is obtained after the reaction is finished. The composite ionic liquid prepared by the method may be used as a catalyst to catalyze an alkylation reaction of isoparaffin with C4 olefin to obtain alkylated oil, which has the advantages of high catalytic activity, long catalytic life, low consumption, and better distribution of the resulting alkylated oil, etc, and thereby significantly reducing the production costs and improving the quality of the resulted alkylated oil.

Abstract: The present invention provides a method of steam cracking using electricity to supply energy. This method is to provide energy for steam cracking reaction of a cracking raw material by electromagnetic induction with electricity; the cracking raw material comprises one or more of naphtha, cycloalkane and cycloolefin; wherein the cycloalkane is a C4-C8 cycloalkane, and the cycloolefin is a C4-C8 cycloolefin. The present invention utilizes electricity to provide energy for the steam cracking reaction through an electromagnetic coil, which is a new use of electricity and solve the current problem of excess electricity. Moreover, utilizing the electromagnetic coil to provide power can make the heat distribution in the furnace tube of the cracking furnace more uniform, and it is easier to control the reaction temperature and the progress of the reaction.
