Fabrication of CaO-Based Sorbents for CO2 Capture by a Mixing Method

摘要: Three types of sorbent were fabricated using various calcium and support precursors via a simple mixing method, in order to develop highly effective, durable, cheap CaO-based sorbents suitable for CO2 capture. The sorption performance morphology the measured thermogravimetric analyzer scanning electron microscopy, respectively. experimental results indicate that cement is promising low-cost precursor contributing enhancement cyclic capacity, especially when organometallic used. A (with 75% CaO content) made from l-lactate hydrate showed highest capacity 0.36 g CO2/g its decreased only slightly after 70 cycles carbonation calcination.
