Advanced porous carbon sorbent for CO2 capture and separation

摘要

The present invention provides a method for producing a porous carbonaceous monolith structure, comprising the steps of: (i) introducing a precursor material containing particles containing a halogenated polymer having a certain melting point into a mold; ) Simultaneously applying a pressure P to the precursor material ranging from 10 to 300 bar if the halogenated polymer is a vinylidene chloride homopolymer and from 10 to 150 bar if the halogenated polymer is different from the vinylidene chloride homopolymer; By maintaining the precursor material at a temperature T1 in the range of, T1, min = 20 ° C. to T1, max = Tm−50 ° C., where Tm is the melting point of the halogenated polymer, Forming a compact containing aggregates of particles, (iii) optionally cooling, then releasing the compact, and (iv) introducing the compact into a furnace. When, to a method and a step of providing thermal decomposition of (v) halogenated polymer in a furnace until the porous carbon monolith structure is obtained. [Selection diagram] None
