FIELD: oil and gas industry.
SUBSTANCE: invention is referred to hydrotreating method for heavy hydrocarbons with system of interchangeable protective areas with fixed beds, at that each bed contains at least two catalytic layers, wherein each time when the catalytic layer at first contacting the raw material is deactivated and/or clogged at stages of the raw material passing through all protective zones the point of raw material entry is moved downstream. The invention also concerns an apparatus for implementation of this method.
EFFECT: suggested invention ensures longer cycle without interruption in operation.
