A novel gas-liquid-solid reactor based on monolith catalyst structure was developed for converting sugar alcohols to value-added chemicals such as propylene glycol. The structured catalyst was used intending to improve product selectivity. Testing at the pressure of 1,200 psig and 210°C with H2 to sorbitol molar ratio of 8.9 and a space velocity range from 0.15 to 5 hr"1 demonstrated that as high as 41 wt% of propylene glycol selectivity and 13 wt% ethylene glycol selectivity can be obtained. In addition, monolith catalysts gave higher C3/C2 ratio than that in the conventional trickle bed reactor with similar liquid hourly space velocities.
