    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 relates to a synthesis method of zeolite 4A, wherein natural clay mineral, provided as the total silicon source and aluminum source required for molecular sieve synthesis, is activated before they are crystallized under hydrothermal conditions to synthesize zeolite 4A. In the method of the present invention, a simple process is employed and inexpensive raw materials are used, resulting in zeolite 4A having a whiteness of 90% or more and a calcium ion exchange capacity of no less than 310 mg CaCO3/g zeolite. According to the present invention, the range of raw materials for the preparation of molecular sieve materials is broadened, and therefore not only the cost for molecular sieve production is greatly reduced by using the sub-molten salt activation method, but also the greenness in the production process of molecular sieve materials is significantly improved.
