A method of converting natural gas or light alkane(s) into unsaturated hydrocarbons, consisting in providing inside of a reaction space a fluidized bed of particles of a refractory and advantageously catalytic material and feeding a plasma of a hydrogen-containing gas and the natural gas or the light alkane(s) into the bed so that the latter effects the quenching of the reaction medium and catalyses the conversion reaction.

Method of conversion of natural gas or of light alkanes into unsaturated

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.

Method of cracking a batch of heavy hydrocarbons into lighter

Plant for the hydrocracking of a feedstock of high-molecular hydrocarbons comprising a fluidized bed of particles within a chamber, injection tube for injecting a fluidizing gas into the bottom of the chamber, tube reactor means on said container for letting said fluidizing gas escape, and a plasma torch of a gas containing hydrogen, which is suitable for injecting the plasma inside the chamber into the fluidized bed of particles.
