ELECTRODES/ELECTROLYTE ASSEMBLY, REACTOR AND METHOD FOR DIRECT AMINATION OF HYDROCARBONS

摘要

An electrodes/electrolyte assembly - MEA, electrochemical membrane reactor - is described and a method for the direct amination of hydrocarbons, namely for the direct amination of benzene to aniline, and a method for the preparation of said electrodes/electrolyte assembly. The presented solution allows the increase of conversion of said amination to above 60%, even at low temperatures, i.e., between 200°C and 450°C; preferably between 300°C and 400°C. The electrodes/electrolyte assembly for direct amination of hydrocarbons comprises: an anode (1) that is an electrons and protons conductor and that includes a composite porous matrix, comprised by a ceramic fraction and a catalyst for said amination at temperatures lower than 450°C; a porous cathode (3) that is an electrons and protons conductor and that comprises an electrocatalyst; an electrolyte (2) that is a protons or ions conductor and electrically insulating, located between the anode (1) and the cathode (3), made of a composite ceramic impermeable to reagents and products of said amination.
