CLEANABLE CERAMIC FILTER OF DIESEL EXHAUST GAS SOLID PARTICLES AND METHOD OF ITS PRODUCTION

摘要

FIELD: process engineering.;SUBSTANCE: invention relates to automotive industry. In compliance with this invention, carbon-bearing and silicon-bearing particles are mixed with organic matter to mould the obtained mix by extrusion. Then, pyrolysis and siliconising are performed. Said organic matter represents polyamide taken in amount of 5-15 wt %. Filter of solid particles thus obtained features BET-surface over 350 m²/g.;EFFECT: better filter efficiency.;6 cl, 1 ex
