Highly effective and durable CO(2) sorbents were synthesized with different calcium and support precursors using a spray-drying technique. It was found that spray-drying could be a useful technique for producing sorbents with enhanced cyclic performance, especially when d-gluconic acids of calcium and magnesium were used. Seven sorbents were synthesized with five calcium precursors and three inert solid precursors, and the sorbent made from calcium d-gluconte monohydrate and magnesium d-gluconate hydrate with 75 wt % CaO content achieved a high CO(2) sorption capacity of 0.46 g of CO(2)/g of calcined sorbent at the 44th cycle of carbonation and calcination.
采用喷雾干燥技术，使用不同的钙和载体前体制备了高效且耐用的 CO(2)吸附剂。研究发现，喷雾干燥技术对于制备具有增强循环性能的吸附剂非常有用，特别是在使用钙和镁的葡萄糖酸时。使用五种钙前体和三种惰性固体前体制备了七种吸附剂，由一水合葡萄糖酸钙和三水合葡萄糖酸镁组成的吸附剂在碳酸化和煅烧的第 44 个循环中达到了 0.46 g 的 CO(2)/g 煅烧吸附剂的高 CO(2)吸附容量。
