Pentosan hydrolysis at low aqueous liquid‐to‐biomass ratios (2.5–15 mL/g) with sulfuric acid as the catalyst is studied in the temperature range of 125–155°C. To facilitate heat transfer and mixing a second insoluble oil is added to the reaction mixture. It is found that even at high slurry concentrations, the reaction is the rate‐controlling step. In addition, such systems give higher pentosan yields compared with dilute slurry systems. This is explained using the concept of acid loading which is defined as the acid present per unit mass of biomass.
