Abstract
Because of their possibly easier processibility compared with lignocellulose, seaweeds are promising biomass resources to produce biofuels and biochemicals. Seaweeds can be fermented to a mixture of organic acids and then further converted by catalytic hydrogenolysis to alcohols. Cu/Zn/Al catalysts are frequently used for the methanol reforming process in addition to the hydrogenolysis reaction. While the conventional coprecipitation method has been used to prepare highly dispersed Cu nanoparticle catalysts, the modified co-precipitation method is developed in order to fabricate the more highly dispersed Cu nanoparticles. Various catalysts were prepared using different conditions, and their catalytic activity and stability were observed using a continuous flow reactor. The prepared catalysts were observed with XRD to confirm the formation of favored precursor complex and their Cu surface area was measured using N2O-chemisorption. BET surface area and pore structures were determined using N2- physisorption, furthermore, TG-DTA, SEM and TEM were also used as tools to understand the relations between catalytic activity and catalyst properties.
