Abstract

A process for manufacturing a dihydrogen-containing outlet gas, including injecting a hydrocarbon inlet gas into a reactor, an operation of cracking the inlet gas with a three-phase plasma torch, and then delivering the outlet gas. The manufacture is carried out from injecting the inlet gas into the reactor to delivering the outlet gas, without either the inlet gas or the outlet gas undergoing expansion.
