Title: Method for swelling calcium oxide-containing material and for making it porous
Inventor: NOJIMA SHIGERU
IPC: C04B2/02
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To develop pores by a simplified process and to enhance gas absorbing performance by exposing a calcium oxide-contg. material such as quicklime to steam and making it porous by heating. SOLUTION: A calcium oxide-contg. material is exposed to steam to form calcium hydroxide and the calcium oxide-contg. material is made porous by heating the calcium hydroxide. When a particulate calcium oxide-contg. material such as quicklime is directly swollen and made porous in the solid state, the calcium oxide-contg. material is swollen by reaction in a vapor phase to form a bulky reaction product and this reaction product is fired or heated. A swelling agent used is preferably steam. Calcium oxide is swollen by reaction with steam to form calcium hydroxide having a larger particle diameter and a larger volume than the calcium oxide.
