Embodiment 1

[0023] Under the condition of constant temperature water bath at 60 °C, 0.68 g P85 and 0.639 g of anhydrous sodium sulfate were dissolved in 30 mL of acetic acid-sodium acetate buffer solution with Ct=0.70 under stirring, and after stirring for more than 6 hours to form a homogeneous system, add 3.54 g 1,2 bis(triethoxysilyl)ethane, stirred for 20 minutes and allowed to stand for 48 hours. Gained liquid was poured into a hydrothermal kettle and hydrothermally heated in a 100° C. oven for 48 hours. After suction filtration and drying at room temperature, the obtained solid was refluxed in ethanol for 12 hours to remove the surfactant to obtain the nano-organosilicon hollow sphere adsorption material.

Abstract

The invention provides a method for preparing an organosilicone hollow-sphere adsorption material. The method is characterized in that the organosilicone hollow-sphere adsorption material product is prepared by the processes including mother liquor preparation, hydro-thermal treatment and backflow removal of a surface active agent. The organosilicone hollow-sphere adsorption material prepared by the method has the characteristics of being small in size, uniform in dispersing, adjustable in aperture, wall thickness and wall, large in specific surface area, high in adsorption performance, and noncombustible; the wall thickness can be adjusted from 1 to 15 nanometers, and the aperture can be adjusted from 5 to 25 nanometers as requirement; the organosilicone hollow-sphere adsorption material can be used as an oil-gas adsorbing material.

Description

technical field [0001] The invention relates to a method for preparing an oil-gas adsorption material by using a sol-gel method in the technical field of oil and gas recovery, in particular to a method for preparing an organic silicon hollow sphere adsorption material. Background technique [0002] Petroleum, petrochemical, chemical and other industries often emit a large amount of volatile organic compounds (VOCs). They not only seriously deteriorate people's living environment and endanger human health, but also bring serious waste of resources, potential safety hazards and economic losses to enterprises and society. With the increasingly stringent standards for VOCs emissions at home and abroad, the treatment and recovery of VOCs has attracted more and more attention. The recovery methods of VOCs mainly include adsorption, absorption, condensation and membrane separation. Some also contain several The integrated utilization of these methods. Adsorption is a common reco...
