Abstract

The invention provides a preparation method of a sponge aluminum matrix composite material for oil-gas separation. The preparation method comprises the following steps: [1] forming periodic nodular CoEr nanofibers supported by a sponge aluminum matrix Al2O3 film; [2] loading MOF with a molecular formula of Er(ETFAA)3(TEOA)2 on the periodic nodular CoEr nanofibers; [3] modifying the sponge aluminummatrix Al2O3 film with a fluorine-containing group. The composite material prepared by the method has excellent super-oleophobic and super-aerophilic characteristics, and low-energy-consumption, high-efficiency and high-flux industrial oil-gas separation can be realized.

Description

technical field [0001] The invention relates to the technical field of oil-gas separation treatment, in particular to a sponge aluminum-based fluorine group-modified Al that can be used for oil-gas separation treatment and has super-oleophobic-super-aeophilic properties. 2 o 3 It supports the preparation method of CoEr nanofiber loaded MOF composite material. Background technique [0002] Due to the precipitation of natural gas stored in the same formation, the crude oil obtained from oil exploitation is often an oil-gas mixture formed by crude oil and natural gas. At this time, the oil-gas mixture needs to be separated from oil and gas to meet the storage, refining and transportation requirements of crude oil and natural gas. [0003] Traditional oil and gas separation technology is mainly divided into gravity oil and gas separation, centrifugal oil and gas separation and filter oil and gas separation according to the principle. Gravity oil and gas separation is to separa...
