MOULDED HETEROGENEOUS CATALYSTS Russian patent published in 2013 - IPC B01J35/02 B01J35/10 

FIELD: chemistry.

SUBSTANCE: invention relates to moulded catalysts, production and use thereof. Described is a catalyst component in form of a cylindrical pellet, having cylinder length C and cylinder diameter D, wherein the outer surface of the component has two or more grooves running along its length, wherein said cylinder has dome-shaped ends of lengths A and B, such that (A+B+C)/D is in the range of 0.50-2.00, and (A+B)/C is in the range of 0.40-5.00. Described is a method of producing said catalyst component, comprising steps of: (i) feeding powdered material, optionally with a pelletising additive, into a pellet mould, (ii) pressing the powder to form a moulded component and then (iii) optionally heating the moulded component to form a moulded catalyst component, wherein said mould has such a shape that the catalyst component has the shape of a cylindrical pellet, having cylinder length C and cylinder diameter D, wherein the outer surface of the component has two more grooves passing along its length, wherein said cylinder has dome-shaped ends with lengths A and B, such that (A+B+C)/D is in the range of 0.50-2.00, and (A+B)/C is in the range of 0.40-5.00.

EFFECT: descried is a catalytic method using said catalyst component, which provides contact between a reaction mixture with the catalyst component in catalysed reaction conditions.
