摘要: Abstract Dilute acid hydrolysis of milled Pinus ponderosa (pinewood) was performed in a high-temperature high-pressure 300 ml SS316 Parr reactor to produce sacrificial electron donors for downstream photocatalytic H 2 generation. Samples the hydrolysate withdrawn at regular time intervals were analysed total organic carbon (TOC), sugars and compounds. The influence type (HCl, SO 4 , HNO 3 ) its concentration, temperature, residence biomass loading on pinewood release glucose xylose (GX) investigated. Maximum GX sugar yield obtained with 1 v/v% HCl 6.66 wt% slurry 180 °C 120 min. treated activated charcoal (AC) photoreformed generation using 1% Pt/TiO catalyst. Under optimized reaction conditions, 8 consecutive cycles produced cumulative 19.9 ml /g pinewood, which is 26 mol% observed hydrolysate.
