Abstract： |
A process for preparing selective catalytic reduction denitration catalyst containes following steps, 1, fly ash and additive are mixed and stirred, active shaping pretreated in reactor, shaped fly ash grain is obtained by pulverizing and sieving fly ash block. 2, soaking shaped fly ash grain by high-concentration strong acid, flushing it to neutrality by distilled water, to form modified SCR denitration catalyst carrier through drying once more. 3, soaking modified SCR denitration catalyst carrier into metal oxide salt solution to obtain the selective catalytic reduction denitration catalyst through two time drying and calcinating. |
