Patent ID: 7410622

Claim:
A reactor for partial oxidations of a fluid reaction mixture in the presence of a heterogeneous particulate catalyst, comprising: at least one cuboidal thermoplate module that includes at least two rectangular thermoplates arranged parallel to each other such that a gap in the at least one cuboidal thermoplate module between respective adjacent rectangular thermoplates is configured to be filled with the heterogeneous particulate catalyst and is configured to receive a flow of the fluid reaction mixture, the at least two rectangular thermoplates being configured to receive a flow of a heat carrier that is configured to absorb a heat of reaction between the fluid reaction mixture and the heterogeneous particulate catalyst and at least partly evaporate; a predominantly cylindrical shell configured to release a pressure formed at the at least one cuboidal thermoplate module, the shell completely surrounding the at least one cuboidal thermoplate module and including a cylinder jacket, a bottom hood configured to seal a bottom end of the shell, a top hood configured to seal a top end of the shell, a longitudinal axis that is aligned parallel to a vertical plane of the at least two thermoplates, a first interior space between the bottom hood and a bottom portion of the at least one cuboidal thermoplate module, and a second interior space between a top portion of the at least one cuboidal thermoplate module and the top hood; and at least one sealing element arranged to limit the flow of the fluid reaction mixture within the shell from the first interior space to the second interior space to only flow through the gap.
