Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In this research, the production of levoglucosan (LG) and levoglucosenone (LGO) was improved from acid-impregnated cellulose via fast pyrolysis. Thermogravimetric and kinetic analysis disclosed the production formation mechanism. The impregnation of acid could reduce the activation energy and lower the reaction temperature. Furthermore, the yield of LG from HPO- and HSO-impregnated cellulose increased significantly (26.4–35.8 wt%) compared with that of pure cellulose (7.5 wt%) pyrolysis at 300 °C. At 350 °C, 0.1 wt% HPO-impregnated cellulose gave a maximum LGO yield (18.3 wt%) via pyrolysis, which increased 36 times concerning that of cellulose without acid impregnation (0.5 wt%). This study exhibited great potential for industrial LG and LGO production from cellulose at low temperatures.
