The invention relates to a process for the production of hydrogen by catalytic reforming of methanol with water vapor. A mixture of methanol, water and carbon dioxide is passed in contact with a catalyst, containing copper, in a fixed bed, in a catalytic zone, at a temperature comprised between 150.degree. and 400.degree. C., the molar ratio of the carbon dioxide to the methanol, at the entrance of the catalytic zone, being comprised between 0.001 and 0.2.

Process for the removal of coke from a coking reactor of a series of coking reactors, comprising the projection of water under pressure at the coke via a water-ejection device hanging from a flexible tube guided by a guide pulley movably mounted above the reactors for translation between each reactor of the series of reactors.

Decoking process and device

A mixture of heavy hydrocarbons, hydrogen and fresh catalyst comprising metals from the groups Vb, VIb, VIIb or VIII is passed first in a furnace for a limited heating time and then in a reactor where recycled catalyst is also added; the recycled catalyst is used in the form of a suspension recovered by fractionation of the reaction product.
