Abstract

Aspen Plus® modelling and simulation of mixed wood sawdust pyrolysis has been reported. This study evaluates the suitability of mixed wood sawdust for biomass pyrolysis. Physiochemical analyses of the sawdust sample were determined in the Aspen Plus® equilibrium model of mixed wood sawdust pyrolysis. Proximate analysis of moisture, ash, volatile matter and fixed carbon contents were 6.93, 2.03, 38.5, and 52.54 wt %, respectively while ultimate analysis of carbon, oxygen, nitrogen, hydrogen and sulfur contents were 61.5, 29.52, 0.67, 7.68, and 0.63 wt %, respectively. Cellulose, hemicellulose, and lignin contents were 68.7, 27.3, and 4.0 wt %, respectively. The study reports predicted sample yields of 56.94, 30.77, and 12.29 wt % for bio-char, bio-oil, and biogas, respectively, at 500 o C and at 1 atm. In the sawdust, fixed carbon content was higher than that of volatile matter. Hypothetical biomass decomposition components used in the Aspen Plus® equilibrium model of mixed wood sawdust pyrolysis influence the predicted pyrolysis products yield.

  • Sawdust is a lignocellulosic byproduct composed mainly of cellulose, hemicellulose, and lignin and is an additional challenging waste stream in wood-based processing industries.

    “Sawdust is one such lignocellulosic byproduct made up mainly of cellulose, hemicellulose, and lignin that serves as an additional yet challenging waste stream in wood-based processing industries”

    From Integrated Techno-Economic, Environmental Screening, and Social Return on Investment Analysis of Community-Scale Sawdust–Polypropylene Co-Pyrolysis for Heavy-Metal Adsorbent Production in Rural Area, Thailand (2026) · cites this paper as [6]

    The Introduction identifies mixed wood sawdust as lignocellulosic biomass whose three main components are cellulose, hemicellulose and lignin; the Results measure all three in a sawmill sample. The Collection and Preparation section establishes the sawmill origin, but the passages do not describe sawdust as an additional, challenging waste stream for wood-processing industries.

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.
