摘要

System for the thermochemical conversion of a carbonaceous charge comprising a batch reactor containing a mixture of supercritical fluid and the charge and a transfer tank containing a chemically inert liquid and connected to the reactor. The invention essentially consists of a thermochemical conversion system operating in cycles with a reactor which carries out the conversion under supercritical fluid, the mixture of which with the products resulting from a cycle is transferred into a transfer tank under the pressure of a liquid which simultaneously fills the reactor by return, a quantity of carbonaceous charge being introduced into the latter at each cycle. During a transfer, the liquid initially contained in the tank is set in motion by a pump and arrives from below in the reactor where it will push the supercritical mixture upwards.
