Abstract
Catalisadores de Pd suportados em Al₂O₃ e CₑO₂/Al₂O₃ foram preparados e testados na reforma a vapor do glicerol. Testes catalíticos foram realizados em um reatorde leito fixo operando continuamente através da injeção de uma carga contendo uma solução de glicerol (10% vol) em água diluída em hélio. A composição da mistura e a seletividade em H2 foram avaliadas nesses catalisadores de acordo com a temperature e tempo de reação, sendo que o catalisador Pd/CeO2/Al2O3 apresentou a maior seletividade em hidrogênio e estabilidade durante a faixa de operaçãopresente neste trabalho.
Pd/Al₂O₃ and Pd/CₑO₂/Al₂O₃ catalysts were prepared and tested in glycerol steam reforming. The catalytic tests were carried out in a fixed bed reactor for continuous flow using glycerol solution 10 vol.% in water diluted in helium. The composition of the mixture and the reaction selectivity in H2was evaluated in these catalysts according to temperature and reaction time on stream, and the Pd/CₑO₂/Al₂O₃ catalyst showed the highest H2 selectivity and stability throughout the operating range study presented this work.
