Abstract

The invention discloses a manufacturing method of a membrane material for nitrogen removal of natural gas. The method comprises the following steps: preparing an ABS (Acrylonitrile Butadiene Styrene) resin support body, etching through holes of the ABS resin support body, depositing aluminum oxide on the surfaces of the through holes of the ABS resin support body, forming a porous metal Au transition layer on the surface of the ABS resin support body, and coating an SBS (Styrene Butadiene Styrene) polymer layer on the surface of the ABS resin support body.

Description

technical field [0001] The invention relates to a selective permeation membrane for the selective denitrification of natural gas and a preparation method thereof. Background technique [0002] As a high-quality fuel and an important chemical raw material, the application of natural gas has attracted more and more attention, and it has become a trend in today's world to accelerate the development of the natural gas industry. However, the natural gas produced in many oil and gas fields often contains a large amount of nitrogen. The high nitrogen-containing natural gas has low calorific value and large energy consumption during the gathering and transportation process, so it cannot be directly used as a fuel. Therefore, natural gas denitrification is an important condition for making full use of natural gas. The natural gas denitrification processes currently used in industry include: cryogenic, solvent absorption, pressure swing adsorption and selective adsorption. Among the...
