Coconut agro-industry in the western region of Thailand generates a large amount of residues. This study investigated the energy production potential of discarded coconut petioles, with a focus on co-gasification with refuse-derived fuel (RDF). Gasification tests involving petioles, RDFs and their mixtures (25%, 50%, 75% or 100% by weight) were conducted in a laboratory-scale fixed bed reactor. Fuel samples of 5 g were gasified at 700°C–900°C for 60 minutes, using simulated air (79% N₂ to 21% O₂, by volume) as a gasifying agent. Gasification of petioles generated producer gas with lower heating values, estimated at 0.43–0.75 MJ Nm⁻³, while RDF produced 0.92–1.39 MJ Nm⁻³. Adding greater quantities of RDF to the fuel mixture resulted in an increase in the heating value of the producer gas and cold gas efficiency. The operating temperatures and gasifying-agent flow rates affected the efficiency of process differently, depending on the fuel composition. However, the maximum cold gas efficiency from both fuels was detected in tests conducted at 800°C. In co-gasification and pure refuse-derived-fuel tests, higher temperatures and gasifying-agent flow rates led to outputs with higher energy yields. Our findings suggested that co-gasification of petiole is a viable alternative waste-treatment technology for this region.

泰国西部地区的椰子农工业产生大量残留物。本研究调查了废弃椰子叶柄的能源生产潜力，重点是与垃圾衍生燃料 (RDF) 的共气化。在实验室规模的固定床反应器中进行涉及叶柄、RDF 及其混合物（按重量计 25%、50%、75% 或 100%）的气化测试。_{使用模拟空气（按体积计 79% N 2}至 21% O ₂）作为气化剂，将 5 g 燃料样品在 700°C–900°C 气化 60 分钟。叶柄气化产生具有较低热值的生产气，估计为 0.43-0.75 MJ Nm ^-3，而 RDF 产生 0.92-1.39 MJ Nm ^-3. 向燃料混合物中添加更大量的 RDF 会提高发生炉煤气的热值和冷煤气效率。操作温度和气化剂流速对工艺效率的影响不同，具体取决于燃料成分。然而，在 800°C 进行的测试中检测到两种燃料的最大冷气效率。在共气化和纯垃圾衍生燃料测试中，更高的温度和气化剂流速导致输出具有更高的能量产量。我们的研究结果表明，叶柄的共气化是该地区可行的替代废物处理技术。
