    Abstract: A honeycomb catalyst body includes a plugged honeycomb structure having porous partition walls, inflow side plugged portions, outflow side plugged portions, and porous projecting portions which project so as to extend from the partition walls into the cells and are formed integrally with the partition walls; and catalyst loaded onto the projecting portions of the plugged honeycomb structure. A porosity of the partition walls of the plugged honeycomb structure is 40 to 70%, a thickness of the projecting portions is from 30 to 140% of a thickness of the partition walls, and an amount of a catalyst loaded onto pore surfaces of the partition walls of the plugged honeycomb structure is smaller than an amount of the catalyst loaded onto the projecting portions. The catalyst loaded onto projecting portions is a three-way catalyst, and the catalyst loaded onto projecting portions is a selective reduction catalyst.

    Abstract: The present invention provides an ultra-stable rare earth type Y molecular sieve and the preparation method thereof, which method is carried out by subjecting a NaY molecular sieve as the raw material to a rare earth exchange and a dispersing pre-exchange, then to an ultra-stabilization calcination treatment. The molecular sieve comprises 1 to 20% by weight of rare earth oxide, not more than 1.2% by weight of sodium oxide, has a crystallinity of 51 to 69%, and a lattice parameter of 2.451 nm to 2.469 nm. In contrast to the prior art, in the molecular sieve prepared by this method, rare earth ions are located in sodalite cages, which is demonstrated by the fact that no rare earth ion is lost during the reverse exchange process. Moreover, the molecular sieve prepared by such a method has a molecular particle size D(v,0.5) of not more than 3.0 μm and a D(v,0.9) of not more than 20 μm. Cracking catalysts using the molecular sieve as an active component is characterized by a high heavy-oil-conversion capacity and a high yield of valuable target products.
