Abstract

A process for reducing the amount of feed gas A in a void volume of solid particles S, whereby solid particles D are obtained, in a reactor, wherein a reaction is carried out, the reactor having a start and an end, wherein the start is preferably a top (T) and the end is preferably a bottom (B) of the reactor, a feed gas inlet A, a gas outlet, a solid particle inlet and a solid particle outlet, the process comprising displacement of at least a part of the feed gas A in the void volume of the solid particles S with a gas B different from said feed gas A, wherein the displacement is carried out by addition of the gas B at the end, preferably at the bottom of the reactor between the feed gas inlet A and the solid particle outlet, wherein the solid particles D are discharged at the bottom of the reactor via a solid particle outlet, or the displacement is carried out by addition of the gas B to a vessel, wherein the solid particles S are collected in the vessel, the vessel being connected with the solid particle outlet at the start, preferably at the top and/or at the end, preferably at the bottom of the reactor;andto a reactor (R) for a reaction of a feed gas A in the presence of solid particles P, preferably a pyrolysis, more preferably a methane pyrolysis, wherein solid particles S are obtained comprising feed gas A in its void volume, the reactor having a start and an end, wherein the start is preferably a top (T) and the end is preferably a bottom (B) and a solid particle outlet at the end, preferably at the bottom and/or at the start, preferably at the top of the reactor, preferably at the end, more preferably at the bottom, a feed gas inlet A, a gas outlet, and a solid particle inlet, and having either an inlet B for a gas B for displacement of the feed gas A in the void volume of said solid particles S for obtaining solid particles D having a reduced amount of feed gas A in a void volume, at the end, preferably at the bottom of the reacfor between the feed gas inlet A and the solid particle outlet, or having an inlet C for a gas B for displacement of the feed gas A in the void volume of said solid particles S for obtaining solid particles D having a reduced amount of feed gas A in a void volume in a vessel, wherein the solid particles S are collected in the vessel, the vessel being connected with the solid particle outlet at the start, preferably at the top and/or at the end, preferably at the bottom of the reactor.
