Abstract

The invention discloses a preparation method of filter material base activated carbon fiber, which takes waste punched felt fiber as a carbon source to prepare the activated carbon fiber through carbonization and KOH chemical activation. The method is low in cost, has high feasibility, can achieve an effect of resource reuse, and simultaneously provides ideal thought for the industrial waste disposal.

Description

technical field [0001] The invention belongs to the field of resource reuse activated carbon preparation of adsorption materials, and in particular relates to a preparation method of filter material-based activated carbon fibers. Background technique [0002] Activated Carbon Fiber (ACF) is developed on the basis of carbon fiber industry and is the third generation product after powdery and granular activated carbon. As a new type of high-efficiency adsorption material, it has large specific surface area, rich micropores, small pore size and narrow distribution, large adsorption capacity, fast adsorption speed, strong adsorption capacity, easy regeneration, and great process flexibility (can be made into yarn, cloth, etc.) , felt, paper and other forms), widely used in chemical industry, environmental protection, catalysis, medical, food hygiene and other aspects. Due to the difference in precursor raw materials, the production of ACF will also be different. Generally speak...
