Abstract

The effect that 6 different biomass feedstocks have on biochar was investigated. The biochar was produced through hydrothermal liquefaction at temperatures of 260˚C and 300˚C. The effect of temperature was also investigated. It was discovered that lower temperatures produce more biochar, but higher temperatures ensure a biochar with properties better suited to be used as catalyst support. The feedstocks did cause the properties to vary and thus it was found that feedstocks with higher fractions of cellulose and lignin will yield larger surface areas, pore volumes and calorific values. The results proved that biochar can compete and eventually replace traditional heterogeneous catalys
