抄録

<p>In this study, liquefaction processes were performed for zelkova and sawtooth oak wastes collected in Saitama City, Japan, divided by site. The reaction conditions were decided using a medium-temperature acid catalyst method to investigate the effects of biomass type, temperature, acid catalyst amount, and solvent amount on the properties of the liquefied products. As a result, biomass liquefaction proceeded at once up to 60 minutes and then slowed down. It was also suggested that prolonged liquefaction beyond 60 minutes may cause an increase in molecular weight due to recondensation, which may affect the utilization of the liquefied product as a resin. Furthermore, the performance of polyurethane foams (PUFs) prepared under various conditions using the liquefied products obtained by liquefaction was investigated through biodegradation and functionality evaluation tests, with the aim of developing PUFs using these liquefaction products.</p>
