5. A device for the direct thermal decomposition of hydrocarbons into solid carbon and hydrogen, comprising:
a. a pre-heating conduit comprising at least one hydrocarbon gas inlet located at a top part of a liquid metal reactor and at least one hydrocarbon gas outlet located at a bottom part of the liquid metal reactor corresponding to the hydrocarbon gas inlet into the liquid metal reactor, and a reactor pool designed for containing a liquid metal media, wherein said pre-heating conduit is located inside a thermal insulation means;
b. the liquid metal reactor further comprises at least one thermal heater located inside the reactor pool for inducing a homogeneous temperature inside the liquid metal reactor;
c. at the top of the liquid metal reactor, at least one carbon extraction system consisting of a porous rigid section is located, said porous rigid section being connected to at least one recipient suitable for collecting carbon particles; and
d. the porous rigid section incorporates, at the top of it, a carbon barrier designed for the carbon particle retention, wherein said carbon barrier separates the porous rigid section from a gas outlet collector.
