Abstract
Abstract A process for the catalytic reforming, with steam in a fluidized bed, of heavy hydrocarbons with a boiling point higher than 220* C., carried out under an effective pressure of 2 to 150 bars, in which the reforming mixture is introduced to the catalyst in the form of catalytic particles of a solid solution of nickel oxide and refractory oxides, with a grain size which is between 1 mm. and 60 Mu , at a temperature between 300* and 700* C., the volumetric speed on the fluidized bed is between 5 and 0.1 liter/hour per liter of catalyst, the ratio between steam and carbon in moles being between 0.75 and 3.0 and without regeneration or reoxidization of the catalyst.
