CATALYST FOR THE REDUCTION OF NITROGEN OXIDES, A METHOD FOR ITS PREPARATION AND THE USE THEREOF |
摘要 |
The invention relates to a catalyst for the reduction of nitrogen oxides and comprises oxides of transition metals on a particulate carrier material, the catalyst comprising: 1) a carrier material consisting of small grains of an in organic oxide, 2) a catalytic layer thereon containing TiO2 and V2O5, and obtained by a separate or simultaneous coating of the components on the carrier material, the catalyst particles being in the order of 10-200 .mu.m and the catalyst being intended to operate at temperatures of 150-220.degree.C. The invention also relates to a method for the preparation of the catalyst, and the use thereof for the reduction of nitrogen oxides in gases at low temperatures.
