Partial oxidation in gas phase of three and/or four carbon precursor compounds to (meth)acrolein and/or (meth)acrylic acid with particulate catalyst in reactor having cuboidal thermoplate modules, cylindrical shell, and sealing element(s)

摘要

Partial oxidation in the gas phase of 3C and/or 4C precursor compounds to (meth)acrolein and/or (meth)acrylic acid in the presence of a heterogeneous particulate catalyst in a reactor having cuboidal thermoplate modules (1), a predominately cylindrical shell (4), and having sealing element(s) which are arranged such that the fluid reaction mixture only flows through the gap. Partial oxidation in the gas phase of 3C and/or 4C precursor compounds to (meth)acrolein and/or (meth)acrylic acid in the presence of a heterogeneous particulate catalyst in a reactor having cuboidal thermoplate modules which are each formed from two or more rectangular thermoplates arranged parallel to each other while in each case leaving a gap which can be filled with the heterogeneous particulate catalyst and is flowed through by the fluid reaction mixture, the heat of reaction being absorbed by a heat carrier which flows through the thermoplates and thus at least partly evaporating; having a predominately cylindrical shell which releases the pressure at the thermoplate modules, completely surrounds them and comprises a cylinder jacket and hoods (15, 16) which seal it at both ends and whose longitudinal axis is aligned parallel to the plane of the thermoplates; and having sealing element(s) which are arranged in such a way that the fluid reaction mixture, apart from flowing through the reactor interior spaces bounded by the hoods, only flows through the gap.
