一种用于油气回收的成型颗粒炭的制备方法
By forming a three-dimensional cross-linked gel structure with chitosan, terminal amino polyether, and octa(aminophenyltrioxosilane), the problems of cumbersome preparation process and low strength in the existing particulate carbon technology are solved. This enables the preparation of molded particulate carbon with high strength and high adsorption performance, simplifies the process, and improves the working capacity of butane.

AI Technical Summary
Existing technologies for preparing granular activated carbon involve cumbersome processes and the use of inorganic binders that cause pore blockage, reducing butane working capacity and making it difficult to simultaneously achieve high strength and high adsorption performance.
Chitosan and terminal amino polyethers were used as organic binders to form a three-dimensional cross-linked gel structure with octa(aminophenyltrioxosilane). Molded granular carbon was prepared by freeze drying, avoiding the high-temperature carbonization step. The cross-linking reaction was further carried out using an aliphatic dialdehyde solution for shaping.
High-strength shaped granular carbon with high butane working capacity was prepared, simplifying the process steps and saving energy and being environmentally friendly.
