Abstract

The invention discloses a method for preparing a eulaliopsis-binata-fiber carbon molecular sieve. The method comprises the steps: (1) modifying eulaliopsis binata fibers; (2) carrying out bonding: mixing the following raw materials in parts by mass: 40-51 parts of modified eulaliopsis binata fiber powder, 10-12 parts of walnut shell powder, 5-8 parts of mica powder, 25 parts of vegetable starch and 18-22 parts of water, and carrying out bonding for 30 to 35 minutes; (3) carrying out forming; (4) carrying out carbonization and pore adjusting treatment; and (5) forming a finished product: rapidly cooling a certain amount of high-temperature sample in a vacuum state.

Description

technical field [0001] The invention belongs to the technical field of macromolecule chemical industry, and in particular relates to a carbon molecular sieve made of asparagus fiber. Background technique [0002] Carbon Molecular Sieve (Carbon Molecular Sieve, CMS) is a non-polar carbon adsorption material with nano-scale ultra-fine pores in a broad sense. Composition, so the pore structure of carbon molecular sieve is very developed, and has unique surface characteristics. Because the wedge-shaped micropores of CMS are close to the diameter of the adsorbed molecules, most of them are effective micropores, and they have the characteristic of adjusting the pore size of CMS according to the molecular size, so they have the ability to screen molecules. The unique pore structure and stable chemical properties of CMS make it widely used in the chemical industry. In addition, it is also widely used in nitrogen and hydrogen production, wastewater treatment, environmental protectio...
