Chemical detoxification of exhaust gases - by reaction of calcium oxide and aluminium powder with water

摘要

Toxic exhaust gases of internal combustion engines and stationary heating installations are detoxified by the use of calcium oxide and/or of earth alkaloid oxides in conjunction with water or steam, when the oxides react to hydroxides. Pref. the earth alkaloid is Al powder. The reaction of oxides to hydroxides in the presence of water produces a large increase in their surface area so the detoxification capacity of the molecules is greatly improved.
