FIELD: chemistry.
SUBSTANCE: method includes feeding a gaseous reagent as gaseous raw material or portion of gaseous raw material with reduced gas flow rate at the input of at least 0.5 m/s into a vessel containing an extended suspended layer of solid catalyst particles, which are suspended in a suspension liquid, such that the gaseous reagent can bubble upwards through the suspended layer, wherein the suspended layer contains a catalyst charge which makes up at least 20 vol % evacuated suspension, catalytic reaction of the gaseous reagent at a pressure higher than atmospheric pressure as bubbles of the gaseous reagent bubble upwards through the suspended layer to form a product, and removing the product and the unreacted gaseous reagent from the vessel.
EFFECT: high efficiency.
