A PRESENTE INVEN??O DIZ RESPEITO A UM NOVO TIPO DE REACTOR QU?MICO, DESCRITO COMO REACTOR CATAL?TICO DE MEMBRANA COM BOMBAGEM ELECTROQU?MICA DE HIDROG?NIO OU DE OXIG?NIO. ESTE NOVO TIPO DE REACTOR ? ESPECIALMENTE APROPRIADO PARA AUMENTAR A SELECTIVIDADE E CONVERS?O EM REAC??ES DE DESIDROGENA??O, HIDROGENA??O, DESOXIDA??O E OXIDA??O NOMEADAMENTE NA REAC??O DE AMINA??O DIRECTA DE HIDROCARBONETOS.ESTE REACTOR PODER? SER UTILIZADO PARA A PRODU??O DE DIVERSOS COMPOSTOS QU?MICOS, COMO POR EXEMPLO, PARA AMINA??O DIRECTA DE HIDROCARBONETOS, EM PARTICULAR PARA S?NTESE DE ANILINA A PARTIR DE BENZENO. NESTA APLICA??O, ONDE SE EFECTUOU A REMO??O DO HIDROG?NIO COM BOMBAGEM ELECTROQU?MICA DE HIDROG?NIO OU A BOMBAGEM DE OXIG?NIO PARA OXIDA??O DO HIDROG?NIO FORMADO, RESULTA NUMA CONVERS?O DO BENZENO EM ANILINA, SUPERIOR A 40 %. The present invention describes a new type of chemical reactor, described as hydrogen or oxygen electrochemical pumping catalytic membrane reactor. This new type of reactor is particularly suitable for increasing the selectivity and the conversion rate of dehydrogenation, hydrogenation, deoxidation and oxidation reactions and namely in the direct amination reaction of hydrocarbons. This reactor can be used for the production of several chemical compounds, such as the direct amination of hydrocarbons and in particular for the synthesis of aniline from benzene. In this application, wherein hydrogen is removed by electrochemical pumping of the hydrogen formed or by oxygen pumping so, as hydrogen is formed, it is oxidized. This new reactor exhibits benzene to aniline conversion higher than 40 %.
