Production of bio-oil via catalytic pyrolysis of medlar seeds

The pyrolysis of medlar seeds was performed at 350, 450, 550, and 650 °C with without K2CO3, MgO, expanded perlite (10 wt%). maximum dichloromethane extract yield (6.70 wt%) obtained 450 in the experiments catalyst, while bio-oil (50.3 presence perlite. yields decreased noticeably use MgO K2CO3. bio-oils from non-catalytic runs mainly consisted phenolic compounds. catalysts had a noticeable effect on composition higher heating values bio-oils. K2CO3 increased relative content 2-methoxyphenol all tested temperatures 2,6-dimethoxyphenol 2,6-dimethoxy-4-methylphenol above 550 °C, led to an increase °C. value (30.4 MJ/kg) This study showed that are good alternative source waste biomass production can be used as biofuel.
