Abstract: A catalytic reactor having a mixing section connected to a downstream reaction section containing a catalyst to promote a reaction of oxygen and a hydrocarbon fed to the catalytic reactor. The mixing section is provided with a flame arrestor to prevent a stable flame from propagating should any reaction of oxygen and hydrocarbons occur during mixing. The flame arrestor permits flow in both axial and radial directions to promote mixing. Baffle elements and a downstream static mixer can also be used. The catalyst is preferably in the form of monolithic blocks enclosed by a ceramic tube that is maintained as a unitary catalyst assembly that can be removed for replacement and installation of the catalyst as a single unit.

Abstract: A catalytic reactor having a mixing section (10) connected to a downstream reaction section (12) containing a catalyst (44) to promote a reaction of oxygen and a hydrocarbon fed to the catalytic reactor. The mixing section (10) is provided with a flame arrestor (30) to prevent a stable flame from propagating should any reaction of oxygen and hydrocarbons occur during mixing. The flame arrestor (30) permits flow in both axial and radial directions to promote mixing. Baffle elements (32) and a downstream static mixer (34) can also be used. The catalyst (44) is preferably in the form of monolithic blocks (46) enclosed by a ceramic tube (48) that is maintained as a unitary catalyst assembly (44) that can be removed for replacement and installation of the catalyst (44) as a single unit.

Abstract: reator catalítico é descrito um reator catalítico que tem uma seção de mistura (10) conectada a uma seção de reação a jusante (12) contendo um catalisador(44) para promover uma reação de oxidação e um leito de hidrocarboneto para o reator catalítico. a seção de mistura (10) é provida com um detentor de chama (30) para impedir que uma chama estável se propague, caso ocorra qualquer reação de oxigênio e hidrocarboneto durante a mistura. o detentor de chama (30) permite o fluxo tanto na direção axial quanto radial para promover a mistura. elementos defletores (32) e um misturador estático a jusante (34) podem também ser usados. o catalisador (44) é preferivelmente na forma de blocos monolíticos (46) encerrados por um tubo cerâmico (48) que é mantido como um conjunto catalisador unitário (44) que pode ser removido para substituição e instalação do catalisador (44) como uma unidade simples.
