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.

First claim

1 - 22 . (canceled)

23 . 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 line 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, in which the at least one reaction device is at least partially arranged in the reaction chamber of the at least one reactor, wherein the at least one reaction device can be heated in the heating chamber for activating the at least one block of solid medium, wherein the reactor chamber has a second opening, which is arranged on the side of the reactor that is opposite from the first opening, wherein the at least one transporting device can be led or has been led through the second opening in order to transport the at least one reaction device, and a second isolating device, by way of which the second opening can be opened and can be closed in a gas-tight manner, wherein the second isolating device has a sealing plate, and wherein, between the sealing plate and a wall section surrounding the second opening, a sealing device is arranged on the side of the sealing plate that is facing away from the reactor chamber.

24 . The reactor system according to claim 23 , wherein the at least one reactor is arranged on the heating chamber, the reactor chamber being connected to the heating chamber via the first opening and being isolatable from the heating chamber by means of the first isolating device.

25 . The reactor system according to claim 23 , wherein the heating chamber comprises at least one radiation opening, wherein concentrated solar radiation can be introduced into the heating chamber through the radiation opening.

26 . The reactor system according to claim 25 , wherein the at least one radiation opening is closed with a disc transparent to solar radiation.

27 . The reactor system according to claim 25 , wherein the heating chamber has walls absorbing solar radiation, wherein solar radiation irradiated into the heating chamber through the at least one radiation opening can be absorbed to heat the walls.

28 . The reactor system according to claim 23 , wherein the at least one reactor is arranged below the heating chamber, and that the transport device is designed as a vertical transport device.

29 . The reactor system according to claim 24 , wherein the heating chamber is adjoined by a receiving chamber separated from the heating chamber via a partition wall, wherein the at least one transport device and the at least one reactor are arranged in the receiving chamber, with the at least one first opening being arranged in the partition wall.

30 . The reactor system according to claim 23 , further comprising: a plurality of structures, each with a reactor chamber, each reactor chamber having a first opening, said first openings each being adapted to be opened and closed in a gas-tight manner by means of a first isolating device, and each reactor having a reaction device.

31 . The reactor system according to claim 30 , further comprising a respective transport device arranged on each reactor.

32 . The reactor system according to claim 23 , wherein the first isolating device has a sliding plate which closes the first opening in a gas-tight manner, or the first isolating devices each have a sliding plate which closes the respective first openings in a gas-tight manner.

33 . The reactor system according to claim 23 , wherein the sealing plate of the second isolating device is designed as a sliding plate, or sealing plates of the second isolating devices are each designed as a sliding plate.

34 . The reactor system according to claim 23 , wherein the reaction device has a base device on which the sealing plate is arranged, or the reaction devices each have a base device on which a sealing plate is arranged in each case.

35 . The reactor system according to claim 23 , wherein the first isolating device has a vacuum seal and/or in that the sealing device of the second isolating device has a vacuum seal.

36 . The reactor system according to claim 13 , wherein the first and/or second isolating device each has a further seal, which reduces convective thermal transport to the vacuum seal.

37 . The reactor system according to claim 25 , wherein the heating chamber has a plurality of radiation openings which are arranged on different sides of the heating chamber.

38 . The reactor system according to claim 3 , wherein the at least one radiation opening has a secondary concentrator or the radiation openings each have a secondary concentrator.

39 . The reactor system according to claim 23 , wherein the heating chamber has at least one vacuum pump.

40 . The reactor system according to claim 23 , wherein the heating chamber has a circular cylindrical shape with a dome-shaped ceiling.

41 . The reactor system according to claim 40 , wherein the underside of the heating chamber is dome-shaped.

42 . The reactor system according to claim 40 , wherein the receiving chamber has a circular cylindrical shape adapted to the heating chamber.

43 . A solar installation with a plurality of solar radiation concentrating reflectors and a reactor system according to claim 23 .

44 . The solar installation according to claim 41 , wherein the concentrating reflectors are designed as heliostats, the heliostats being arranged in subarrays whose position is adapted to the individual positions of the radiation openings.
