Smoke removal treatment agent and smoke removal treatment manner

摘要

PURPOSE: To provide an exhaust gas treatment agent, dry type or semi-dry type and inexpensive and of high activity, by using a calcium chloride alone, or in combination with a calcium compound as a substitution reactive substance for a substance to be treated in the exhaust gas. ;CONSTITUTION: A calcium chloride alone or in combination with a calcium compound such as calcium carbonate or calcium hydroxide is added as a substitution substance for a substance to be treated in exhaust gas. At that time, 99.9-1wt.% calcium chloride is contained, and the content weight ratio of calcium hydroxide to calcium sulfite is set to be 100:1 to 10:(1-30). Thus, calcium chloride is applied as an exhaust gas-treating agent, and also calcium carbonate is activate and converted to be highly functional to give an exhaust gas-treatment agent active even at low temperature.;COPYRIGHT: (C)1996,JPO
