FILTER FOR ABSORPTION OF SOLID PARTICLES FROM COMPRESSION-IGNITION ENGINE EXHAUST GASES |
摘要 |
FIELD: process engineering.SUBSTANCE: invention relates to filter designed to remove solid particles and nitrogen oxides from exhaust gases. Filter comprises porous substrate with inlet and outlet surfaces and substrate pores of the first average size. Note here that said porous substrate is coated by material increasing the surface area. Said material includes molecular sieve promoted by transition metal wherein aforesaid coat represents a porous untreated coat on inlet and/or outlet surface. One of plies has pores of the second average size, smaller than the first one.EFFECT: balanced backpressure, efficient filtration and catalytic activity.17 cl, 7 dwg, 3 ex |
