Description:
Although inert supports have been proved effective to enhance CO 2 capture performance of CaO sorbents, more commonly used supports are derived from expensive raw materials (such as nitrates and organometallic precursors). This work utilized cheap waste sludge from the steel plant, which is of a high daily output and has not received effective reuse, to promote the CO 2 capture performance. The results showed that the sludge effectively promoted the performance of limestone. Homogeneously dispersed inert material of MgO, acting as the metal framework to resist sintering, was responsible for the enhanced performance. The introduction of waste sludge into the calcium looping could not only improve the sorbent performance, but also provide a potentially effective way to reuse the waste sludge.
