Method of recovery of calcium sorbent for trapping COsub2�/sub in chemical loop

摘要

the invention relates to the regeneration of calcium sorbent for co2 capture loop chemical, which is that in the first stage sorbent deactivated calcium favourably of size size distribution from 200 - 700u00b5m, after the calcination or karbonatyzacji undergo hydration bye ru0105 water temperature from 110 to 200u00b0c or water temperature from 20 to 100u00b0c for a period of from 15 to 60 min,and then in the second stage sorbent is exposed to gas of co2 concentration above 50% at a temperature of from 50 to 150u00b0c for a period of from 5 to 15 min, after which sorbent again undergo calcination process in temperature of 850 - 1000u00b0c and another karbonatyzacji in subsequent cycles.
