The invention relates to a processing system comprising a processing unit (1, 60, 100) that can be operated between an upper (To) and a lower (Tu) temperature. A first heat accumulator (3, 61) and a second heat accumulator (4, 62) are operationally interconnected by means of a line arrangement (L) for a heat-transporting medium, said processing unit (1, 60, 100) being arranged in a first section (I) of said line arrangement (L) between the first (3, 61) and the second heat accumulator (4, 62).

The present disclosure is directed to systems and methods to control particle mass flow rate in solar receivers and associated heat exchangers based on feedback from one or more temperatures of particles in the system.

Process for cracking hydrocarbon gases, wherein the hydrocarbon gas is passed through a flow channel of an absorptive receiver reactor (1, 30, 40), characterized in that cracking takes place during the passing through the receiver reactor (1, 30, 40), wherein in a first region (21) of the flow channel (2) the hydrocarbon gas is heated to its cracking temperature, in an adjoining second, downstream flow region (22) is heated to beyond its cracking temperature and in a third, further downstream region (23) of the flow channel is heated yet further and is brought therein into physical contact, over the cross-section of said region, with a reaction accelerator, after which the stream of products downstream of the reaction accelerator is discharged from the receiver reactor (1, 30, 40), and wherein the heating of the hydrocarbon gas to above its cracking temperature is achieved by absorption of blackbody radiation (20) which is given off by the reaction accelerator heated by solar radiation (7) incident thereupon to the hydrocarbon gas flowing towards it, in such a way that the hydrocarbon gas in the flow channel (2) and extending up to the reaction accelerator forms disc-shaped, consecutive temperature zones (60 to 67) of ever-increasing temperature extending transversely to the flow channel (2).
