Gasification represents an attractive pathway to generate fuel gas (i.e., syngas (H₂ and CO) and hydrocarbons) from oil palm biomass in Malaysia. Torrefaction is introduced here to enhance the oil palm biomass properties prior to gasification. In this work, the effect of torrefaction on the gasification of three oil palm biomass, i.e., empty fruit bunches (EFB), mesocarp fibres (MF), and palm kernel shells (PKS) are evaluated. Two gasifying agents were used, i.e., CO₂ and steam. The syngas lower heating values (LHV_syngas) for CO₂ gasification and steam gasification were in the range of 0.35–1.67 MJ m⁻³ and 1.61–2.22 MJ m⁻³, respectively. Compared with EFB and MF, PKS is more effective for fuel gas production as indicated by the more dominant emission of light hydrocarbons (CH₄, C₂H₄, and C₂H₆) in PKS case. Gasification efficiency was examined using carbon conversion efficiency (CCE) and cold gas efficiency (CGE). CCE ranges between 4% and 55.1% for CO₂ gasification while CGE varies between 4.8% and 46.2% and 27.6% and 62.9% for CO₂ gasification and steam gasification, respectively. Our results showed that higher concentration of gasifying agent promotes higher carbon conversion and that steam gasification provides higher thermal efficiency (CGE) compared to CO₂ gasification.

气化是从马来西亚的油棕生物质中产生燃料气体（即合成气（H ₂和CO）和碳氢化合物）的有吸引力的途径。这里引入焙干以增强气化之前油棕的生物质特性。在这项工作中，评估了烘焙对三种油棕生物质气化的影响，即空果串（EFB），中果皮纤维（MF）和棕榈仁壳（PKS）。使用了两种气化剂，即CO ₂和蒸汽。CO ₂气化和蒸汽气化的_合成气低热值（LHV_合成气）在0.35–1.67 MJ m ^-3和1.61–2.22 MJ m ^-3的范围内， 分别。与EFB和MF相比，PKS在燃料气体生产方面更为有效，这在PKS案例中显示出轻烃（CH ₄，C ₂ H ₄和C ₂ H ₆）的排放更为占优势。使用碳转化效率（CCE）和冷气效率（CGE）检查了气化效率。对于CO ₂气化，CCE介于4％和55.1％之间，而对于CO ₂气化和蒸汽气化，CGE分别介于4.8％和46.2％之间以及27.6％和62.9％之间。我们的结果表明，与CO ₂相比，更高浓度的气化剂可促进更高的碳转化率，并且蒸汽气化可提供更高的热效率（CGE）。 气化。
