Abstract: A reactor system with a heating chamber, with at least one reactor with a reactor chamber, which has a first opening, and with a first isolating device, by way of which the first opening can be opened and can be closed in a gas-tight manner, wherein a conducting device for supplying and/or removing fluid is connected to the reactor chamber, wherein the at least one reactor has at least one reaction device with at least one block of solid medium, and with at least one transporting device, by way of which the at least one reaction device can be transported out of the reactor chamber through the first opening into a first position, in which the at least one reaction device is at least partially arranged in the heating chamber, and out of the heating chamber into a second position.

Abstract: A reaction device for a thermochemical reactor system, having at least one base device and having at least one solid-medium block. at the at least one solid-medium block is arranged on the base device, and extends along an axial direction with at least one thermochemical reaction material. The least one solid-medium block has at least one shaft that has at least one inlet opening and/or at least one outlet opening.

Abstract: A solar radiation receiver having a receiver chamber having at least one radiation opening through which concentrated solar radiation can be introduced into the receiver chamber, having at least one solar absorber device which has at least one solid medium block which is fastened to a transport device, and having at least one opening through which the at least one solar absorber device is inserted such that the at least one solid medium block is arranged in the receiver, and through which the solar absorber device is removed.

Abstract: The present invention relates to a process for performing a chemical reaction consisting of at least two sequential reversible steps characterized by being performed in a cycle, and to a reactor for performing such process.
