Previous issue date: 2010-06-10 / Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico / Supported catalysts of CuCl2 on s?lica were used in the methane oxychlorination
reaction. The materials were synthesized by the ion exchange technique in a basic
solution, using a copper-ammonia complex with 3 and 6 % of nominal copper loading.
The materials where characterized by thermogravimetry (TG), X-ray Fluorescence
Spectroscopy (XRF), Temperature Programmed Reduction (TPR), Scanning Electron
Microscopy with X-ray microanalysis (SEM/EDS), BET specific area and pore
distribution. The characterization confirms the presence of copper on the support
surface, concluding that the ion exchange technique was adequate in the catalyst
synthesis. For the reaction test, an oxychlorination bench scale unit was employed. The
tests were carried at 673 and 773 K. The results showed the influence of temperature
and catalyst copper content on the oxychlorination of methane reaction / Catalisadores do tipo CuCl2 suportados em s?lica, utilizados na convers?o do metano via oxiclora??o, foram sintetizados pelo m?todo de troca i?nica em meio b?sico, usando um complexo amoniacal de cobre, com cargas met?licas nominais de 3 e 6% de
cobre. Os materiais foram caracterizados por: termogravimetria (TG), fluoresc?ncia de raios X (FRX), redu??o ? temperatura programada (RTP), microscopia eletr?nica de varredura com espectroscopia dispersiva de el?trons (MEV-EDS) e determina??o da ?rea especifica e volume de poro pelo M?todo BET. Os resultados das caracteriza??es indicavam a presen?a de cobre na superf?cie do suporte mostrando que o processo de impregna??o via troca i?nica foi adequado na s?ntese do catalisador. No teste catal?tico reacional foi utilizada uma planta de oxiclora??o, em escala de laborat?rio. Os experimentos catal?ticos foram avaliados nas temperaturas de 673 e 773 K. Os resultados obtidos mostraram influ?ncia da temperatura e teor de cobre dos catalisadores na rea??o de oxiclora??o do metano
