ABSTRACT:
A method of cracking heavy hydrocarbons into lighter hydrocarbons consisting in providing an advantageously catalytic bed of particles in a reaction chamber, feeding a bed fluidizing gas with a predetermined flow rate to provide a springing fluidized bed and feeding a plasma jet preferably containing argon into the chamber, the jet being directed towards a determined place of the bed so as to provide a reaction space with at least two reaction zones of different temperatures, the zone of higher temperature being the one where the plasma jet is directed; feeding heavy hydrocarbons into the reaction zone of lower temperature and feeding preferably in the zone of higher temperature at least one light alkane for carrying out the cracking of the heavy hydrocarbons within the fluidized bed, the latter effecting a quenching of the reaction medium and catalysing the cracking and consisting in discharging the products obtained downstream of the zone of lower temperature.
