“…For coals of various rank, the concentration of syngas has been reported to range between 58% and 83% [6,17,26], while for some agricultural residues, such as cotton straw, corn stalk and rice husk, it is reported to vary between 61% and 74% at temperatures of 800-900 °C [4,5,31]. The distribution of gases within the generated product at 1000 °C was reflected in the higher heating value of the gas mixture from the gasification of the fuels For coals of various rank, the concentration of syngas has been reported to range between 58% and 83% [6,17,26], while for some agricultural residues, such as cotton straw, corn stalk and rice husk, it is reported to vary between 61% and 74% at temperatures of 800-900 • C [4,5,31].

“…The co-gasification of low-rank coals with agricultural wastes for the production of syngas under a steam or carbon dioxide atmosphere has not been sufficiently studied. The co-processing of lignite with wheat straw [26] or sunflower seed cake [6] via steam gasification showed that the biomass material exhibited a positive synergetic effect on the blends, attributed to the volatile content of biomass and the inherent alkali/alkaline earth metals. Similar results were obtained by the carbon dioxide gasification of lignite with soybean stalk or orange peel [14].…”

“…Under these conditions, the predominant product is the gas fraction, which accounts for 85% [Malińska et al, 2014]. The fast pyrolysis process takes place under conditions of rapid temperature rise (> 103 °C•s -1 ) and short reaction time (< 2 s) with rapid cooling of volatiles leading to the formation of biooil and biochar as an intermediate [Zhao et al, 2020]. In addition, catalysts and microwave assistance are often used in the thermal conversion of biomass to improve product distribution and quality [Lu et al, 2021;Zulkornain et al, 2022].…”

“…Co-pyrolysis includes the devolatilization of biomass and coal to form coke, tar and gases, resulting in solid-gases and gases-tar reactions [16][17][18]. The high hydrogen content indicates that biomass could act as a hydrogen donor in co-pyrolysis with coal [6,19,20]. Hence, co-pyrolysis of coal and biomass can not only pave the theoretical support for greater efficiency with better utilization of biomass and coal, but also reduce the activation energy of the reaction for co-pyrolysis of coal and biomass [21,22], which are conducive to industrializing and large-scale development.…”
