结合生产实践，提出了在蜂窝式SCR脱硝催化剂制造的6道工序中，混炼、一段干燥、焙烧3道工序是影响催化剂产品质量的关键工序。从理论上对以上关键工序进行了分析：混炼是保证各种原料能够达到“分子接触”的关键；一段干燥是使蜂窝体不变形、不开裂从而保证产品合格率的关键；焙烧是使催化剂产品具有大的比表面积、大的孔隙率、合理的孔径分布以及达到规定的机械强度的关键。

Combining with the manufacturing of cellular SCR denitration catalyst, it proposes the six procedures, analyzes three key procedures of these processes such as mixing, first drying and roasting.Based on theory anal-ysis for these procedures, it shows that the mixing procedure is the key of"molecules"to achieve all kinds of raw materials, first drying procedure is to keep the cellular body no deformation and cracking, to guarantee the quali-fied product rate, roasting procedure is to product catalyst products with a large specific surface area, large po-rosity, reasonable pore size distribution.
