FIELD: oil-and-gas industry.
SUBSTANCE: invention relates to preliminary passivation for continuous reforming plant before reaction or after passivation during initial reaction. Proposed method comprises loading reforming catalyst in continuous reforming plant, starting gas circulation to increase reactor temperature, adding sulphide to gas at reactor temperature of 100-650°C, and adjusting sulfur content in circulating gas at the level of 3-20×10-6 l/l.
EFFECT: deceleration of metal catalytic activity on walls, reduced risks of emergent operation.
