Abstract [en]

An efficient approach was proposed to convert biomass gasification tar into syngas via electrochemical catalytic reforming (ECR) using the Ni-CeO2/γ-Al2O3 catalyst. Three tar model compounds (toluene, benzene and 1-methyl naphthalene) were selected for ECR experiments in a lab-scale experimental set where an electrified Ni-Cr wire was installed in the catalyst bed to provide thermal electrons. Experiments were performed to reveal the effects of several factors on the conversion of the tar model compounds and product gas composition, as well as the catalytic stability over a long experimental period. The results indicated that the presence of the electric current enhanced the performance (carbon conversion and anti-coke deposition) of the catalyst remarkably. The toluene conversion reached as high as 99.9% under the electric current of 4 A, temperature of 850 °C and steam/carbon (S/C) ratio of 3.
