Carbonized wood quality varies, being influenced by their physical and combustion properties, which determine their suitability as biofuels. The physico-combustion properties of charcoals from six defect-free, regularly-used tropical timbers for carbonization (i.e., Anogeissus leiocarpa, Erythrophleum ivorense, Ficus sur, Berlinia occidentalis, Azadirachta indica and Vitellaria paradoxa) from Donkorkrom, Ghana, were studied. The timbers were randomly selected to avoid bias and the experiments setup in a Completely Randomized Design (CRD). The carbonized woods’ qualities were ranked 1 (best) to 6 (worst) based on the cumulative average of their properties. Charcoal yield was greatest for E. ivorense (41.49 ± 4.65%), and least for F. sur (22.26 ± 4.71%). Moisture contents (MCs), densities, ash contents for the carbonized woods (i.e., <8%, >130 kg m⁻³, <8% respectively) met the standards for trade on the International and European markets. E. ivorense charcoal recorded the greatest Water Resistance Capacity (96.333 ± 0.57%), least burning rate (5.104 ± 0.08 g min⁻¹) and Specific Fuel Consumption (127.1443 ± 4.867 g L⁻¹). Their CVs (26939.24 ± 105.91 J g⁻¹ for B. occidentalis to 29177.44 ± 558.77 J g⁻¹ for A. leiocarpa) were also greater than the typical values (19400 J g⁻¹ to 20400 J g⁻¹) by ISO. E. ivorense charcoal ranked best, while B. occidentalis and F. sur charcoals ranked worst. However, all the charcoals would perform well outdoors, suitably for domestic utilization (e.g. cooking and baking). In metallurgy, E. ivorense and A. leiocarpa carbonized woods would be most thermally-efficient.

炭化木材的质量各不相同，受其物理和燃烧特性的影响，这决定了它们作为生物燃料的适用性。研究了来自加纳 Donkorkrom 的六种无缺陷、经常使用的热带木材（即Anogeissus leiocarpa、Erythrophleum ivorense、Ficus sur、Berlinia occidentalis、Azadirachta indica和Vitellaria paradoxa）的木炭的物理燃烧特性。随机选择木材以避免偏差和完全随机设计（CRD）中的实验设置。根据其特性的累积平均值，将碳化木材的质量分为 1（最好）到 6（最差）。E. ivorense 的木炭产量最高(41.49 ± 4.65%)，对于F. sur (22.26 ± 4.71%)最少。碳化木材的水分含量 (MCs)、密度、灰分含量（即分别<8%、>130 kg m ^-3、<8%）符合国际和欧洲市场的贸易标准。E. ivorense木炭记录了最大的防水能力 (96.333 ± 0.57%)、最小的燃烧率 (5.104 ± 0.08 g min ^-1 ) 和比燃料消耗 (127.1443 ± 4.867 g L ^-1 )。它们的CV（26939.24±105.91Ĵ克^-1为B. occidentali s到29177.44±558.77Ĵ克^-1为A. leiocarpa）比的典型值（19400Ĵ克还大^-1到 20400 J g ^-1 )，通过 ISO。E. ivorense木炭排名最好，而B. occidentali s 和F. sur木炭排名最差。然而，所有木炭在户外都表现良好，适合家庭使用（例如烹饪和烘焙）。在冶金方面，E. ivorense和A. leiocarpa碳化木材的热效率最高。
