The present work is to study the effect of pressure on the gasification of sugarcane bagasse in a pressurized circulating fluidized bed reactor. The range of operating pressure is maintained at 1–4 bar, and thereby the composition of generated syngas is measured with the help of gas chromatography. The gasification parameters like dry gas yield, lower heating value (LHV), cold gas efficiency (CGE), and carbon conversion efficiency (CCE) have been calculated from the syngas composition. The output yields some interesting results, i.e., with the increase in pressure from 1 to 4 bar, and there is an increment of concentration value by 26% for CH₄ as well as CO₂. However, a decreasing trend of H₂ concentration (7.62–6.75% by volume) is observed for the same pressure rise. In addition, it has been observed a little deviation in the trend for CO (16.39–16.86%), which bears an increasing trend from a pressure of 1–2 bar and a decreasing trend thereafter. Following a similar trend for CO, the LHV first increases from 4013 to 4200 kJ Nm⁻³ with an increase in pressure from 1 to 2 bar and thereafter decreases gradually to 4081 kJ Nm⁻³ at a pressure of 4 bar. Apart from these parameters, gas yield, CCE, and CGE values imparted positive effects with pressure rise, and the magnitudes increased from 0.93 to 1.27 Nm³ kg⁻¹, 38.3–57.5 and 23.3–32.3%, respectively, with an increase in pressure from 1 to 4 bar. The exergy destruction and exergy efficiency are observed to be 140 MW and 76% at 4 bar operating pressure.

目前的工作是研究压力对加压循环流化床反应器中甘蔗渣的气化的影响。工作压力范围保持在1-4 bar，从而借助气相色谱法测量生成的合成气的成分。由合成气组成已计算出气化参数，如干气产率，较低的热值（LHV），冷气效率（CGE）和碳转化效率（CCE）。输出产生一些有趣的结果，即压力从1 bar增加到4 bar，CH ₄以及CO ₂的浓度值增加了26％。但是，H ₂的下降趋势对于相同的压力上升，可观察到浓度为（7.62-6.75％体积）。此外，已经观察到CO趋势略有偏差（16.39-16.86％），该压力在1-2 bar的压力下呈上升趋势，此后呈下降趋势。遵循CO的类似趋势，随着压力从1 bar增加到2 bar ，LHV首先从4013 kJ Nm ^-3增加到4200 kJ Nm ^-3，然后在4 bar的压力下逐渐降低到4081 kJ Nm ^-3。除这些参数外，气体产率，CCE和CGE值对压力升高也产生了积极影响，其强度从0.93升高至1.27 Nm ³  kg ^-1，压力分别从1 bar增加到4 bar，分别为38.3-57.5和23.3-32.3％。在4 bar的工作压力下，观察到的火用破坏和火用效率分别为140 MW和76％。
