An engineered process of manufacturing a carbon capturing agent calcium aluminum carbonate Ca&#x2014;Al&#x2014;COincludes steps of mixing, solid-liquid separation, drying and extrusion, crushing and conveying, and calcined molding. The acid bath of Caand Alis mixed with the alkaline bath of NaCOand NaOH while stirring to form slurry which are then subject to solid-liquid separation to obtain a filtrated cake. The filtrated cake is place into a drying and extrusion device to obtain granular material. The granular material is placed in a conveying and crushing equipment to obtain a powder material. The powder material is calcined at furnace for forming a Ca&#x2014;Al&#x2014;CO, which is nano-layered composite with high porosity. Thereby, the preparation of a solid sorbent can be scale up under systematically controlled with yield of at least batches of kilograms used in medium-high temperature (400&#x2dc;800&#xb0; C.) COcapture.

A novel method for making a COcapture agent is provided. The capture agent is made of a calcium/iron salt. The capture agent is prevented from degradation at high temperature. The capture agent is fit to be used at various temperatures in high COdensities for achieving high COcapture capacity, environmental protection and low power consumption.
