Co-gasification of renewable biomass and coal is a promising technique to reduce greenhouse gas emission beside increasing gasification performance instead of individual coal gasification. In this study, the co-gasification performance of pine bark (PB) biomass and Barapukurian bituminous coal (BBC) have been assessed using a high-temperature entrained flow gasifier using CO₂ reactant. Results show that increasing biomass concentration increases the carbon conversion, syngas quality and cold gas efficiency (CGE), while reduces emission. For example, an addition of 20% biomass with coal increased the carbon conversion by 21.5, 10.6 and 4.5%-point at temperatures of 1000, 1200 and 1400 °C compared to pure coal gasification. Similarly, increasing biomass ratio in the blend increased the yield of CO by 11–36 vol% under different temperatures. Also, the CGE, fragmentation index ($FI=\sum _i^n\frac{F}{D_o}$) and alkali and alkaline earth minerals in ash were increased with increasing biomass ratio in the blend. Overall, at least 50% of coal can be replaced with renewable biomass considering performance and emission characteristics, making the technology more sustainable.

可再生生物质和煤炭的共气化是减少温室气体排放的有前途的技术，除了提高气化性能而不是单独的煤气化。在这项研究中，使用高温夹带气流气化炉和CO ₂评估了松树皮（PB）生物质和Barapukurian烟煤（BBC）的共气化性能。反应物。结果表明，增加生物质浓度可提高碳转化率，合成气质量和冷气效率（CGE），同时减少排放。例如，与纯煤气化相比，在1000、1200和1400°C的温度下，煤中添加20％的生物质可将碳转化率提高21.5、10.6和4.5％。同样，在不同温度下，共混物中生物量比例的增加使CO的产率提高了11–36 vol％。此外，CGE的碎片指数（$F\mathrm{一世}=\sum _{\mathrm{一世}}^{ñ}\frac{F}{d_{Ø}}$），灰分中的碱金属和碱土金属矿物质随着生物量比率的增加而增加。总体而言，考虑到性能和排放特性，至少有50％的煤炭可以被可再生生物质替代，从而使该技术更具可持续性。
