Influence of the Heating Rate and the Type of Catalyst on the Formation of Key Intermediates and on the Generation of Gases During Hydropyrolysis of Glucose in Supercritical Water in a Batch Reactor

Abstract

To understand the influence of experimental conditions on the chemistry of biomass degradation in supercritical water, the effect of heating rate and of different catalysts (1 wt % of Raney nickel and 0.5 wt % K 2 CO 3 ) on the product distribution during hydropyrolysis of glucose is investigated. Glucose in aqueous solution (5 wt %) is selected as a model compound for cellulosic biomass. The heating rates are 1 or 3 K/min up to 500 °C, and then, the reactor is kept at this temperature for 1 h. Despite the long reaction time of 1 h at 500 °C, the presence of catalysts has an significant influence on intermediates of glucose gasification such as phenols or furfurals. The influence of catalyst and the heating rate on these intermediates and the product yields points to the assumption that the chemical processes during heating have a drastic effect on the results of the gasification process at 500 °C.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
