Abstract

A method is suggested to produce aldehydes from unsaturated hydrocarbons, carbon monoxide and hydrogen in the presence of continuously circulating catalyst – metallic cobalt. To simplify and intensify the process, the stages of carbonyl formation and carbonylation in the presence of fine dispersed cobalt powder are carried out simultaneously in the same reactor without using supports, thickeners and other extraneous agents. Thermal decobaltization of the product containing dissolved cobalt carbonyls is carried out in an apparatus of a mixer or coil type. The recovered cobalt is separated by means of electromagnetic cyclone and returned to the reactor with the feed stream.

Reactor operation conditions: pressure 150-300 atmospheres, temperature 120-170°C, feeding rate: 1-4 volumes of the feed per reactor volume during 1 h.

Decobaltization conditions: temperature 150-200°C, pressure 5-300 atm.
