FIELD: petrochemical processes.
SUBSTANCE: methylacetylene and propadiene are selectively hydrogenised in propylene-enriched stream. Hydrogenation is carried out stepwise in first single-passage fixed-bed reactor and then in distillatory reactor containing, as hydrogenation catalyst, supported PdO serving as distillation system component.
EFFECT: increased conversion and selectivity with respect to propylene.
