It seeks to establish an optimisation methodology for achieving desired product yields and qualities by means of adjusting the post-reformer temperature. Five different feedstock materials are studied: straw, bio-stabilised compost, and three feedstock materials, which are mixtures of horse manure, straw, sawdust, and miscanthus in varying proportions. Two sets of experiments, one at a post-reformer temperature of 500 °C and the other at 700 °C, are carried out on all the feedstock materials. The results show that a greater biogas yield is achieved at the higher post-reformer temperature, but at the expense of the other products: biochar, process water, and biooil. Moreover, the hydrogen fraction of the biogas is larger in the higher post-reformer temperature trials. In addition, the biooils and process waters produced at the higher post-reformer temperature of 700 °C have fewer impurities, and the biooils are less acidic because of better reforming. However, there is no clear trend regarding the change in the calorific value of the biooil with post-reformer temperature. Finally, the overall qualities of all products improve when the post-reformer temperature is increased.enbiogasheating valuehydrogenpost-reformer temperaturepyrolysisthermo-catalytic reformingposter
