Degradation Kinetics of Arabinose and Furfural in Subcritical Water

Abstract:

To clarify the degradation mechanism of arabinose in a subcritical water system, the degradation process kinetics of arabinose and furfural in a subcritical water system was studied for temperatures from 210 to 250°C and under pressure of 10Mpa. The activation energy and frequency factor for the degradation of each substrate were estimated from the temperature dependence of the rate constant. The molar yield of a arabinose to furfural was ca. 0.3 at any temperature, Acidic compounds were also formed from the arabinose in proportion to the amount of consumed substrates. The formation of acidic compounds resulted in a rapid decrease in pH.
