Limestone and lime are used for high-temperature DeSOx sorbent. However, the porosity of them is usually very low, and their SO_2 removal capacity is low. As the solution of problems, we presented method of macroporous lime using acetic acid, water vapor and water. In this study, a wet swelling method with acetic acid aqueous was studied for the development of a low cost swelling method. It was found that this wet swelling method with acetic acid aqueous solutions was usual method for the preparation of macroporous lime.
