FIELD: oil and gas industry.
SUBSTANCE: invention relates to reactors of catalytic cracking. A riser reactor of catalytic cracking is described, stretching between an entrance for hydrocarbon raw materials and catalyst particles and an exit for outgoing cracked products and particles of spent catalyst, at the same time this riser reactor is equipped with an inner refractory lining and at least one contact device, differing by the fact that the specified contact device contains a composite of refractory material and a metal structure, which is fixed on the outer wall of the riser reactor.
EFFECT: specified metal structure provides for tight adhesion and reinforcement of refractory material.
