FIELD: process engineering.
SUBSTANCE: invention relates to catalyst carrier substrate and method of its production. Metal or ceramic substrate of solid catalyst carries with coat, its thickness varying from 5 to 100 mcm and made from first-coat composition to increase surface area, comprises catalytic component, metal oxide and heatproof fibrous or filament material. Said material features its length-to-thickness ratio exceeding 5:1. Proposed method consists in applying suspension containing first-coat composition onto substrate.
EFFECT: higher wear resistance of coat.
