METHOD FOR HYDROGENATING TRANSFORMATION OF HYDROCARBON RAW STOCK Russian patent published in 2006 - IPC C10G49/00 

FIELD: oil refining.

SUBSTANCE: heavy hydrocarbonaceous charge is subjected to hydrogenation transformation in reaction zone, which includes a layer, containing immobile row of porous catalyst particles, by means of contact of charge with watered gas in conditions, which provide for distribution of charge, primarily in liquid phase, in technological conditions of increased pressure and increased temperature, across the layer of catalyst for flowing downwards and contacting catalyst particles. Watered gas is injected into reaction zone below layer of catalyst, for setting up counter-flow contact of ascending gas flow with descending liquid, letting out processed liquid below catalyst layer and removing fluid substance with low content of hydrogen above the catalyst layer. Catalyst layer has volumetric share of cavities less than 0,5, while gas/liquid contact is realized in conditions, under which Peclet number value for liquid is maintained in range between 0 and 10.

EFFECT: increased conversion of raw stock and increased selectivity of end product.
