ABSTRACT

Charcoal is a brittle, black carbon residue produced from the carbonization of cellulosic materials for energy. Its properties vary per the timber carbonized. It is often used regardless the intended purpose and the timber carbonized. However, for objective utilization, the proximate and strength properties of carbonized woods from six widely-used timbers in the Afram Plains, Ghana, were investigated. Moisture content for the carbonized woods met the recommended Standards. Hence, would be hardly alterable under normal atmospheric conditions. Their bulk densities ranged from 497.39 ± 3.13 kgm⁻³ (Azadirachta indica) to 680.50 ± 8.58 kgm⁻³ (V. paradoxa). E. ivorense charcoal produced the least volatile matter (VM) (18.66 ± 0.73%), ash (1.94 ± 0.04%), much great Calorific value (28208.45 ± 743.72 kJkg⁻¹), the greatest Fixed Carbon Content (73.13 ± 0.69%), Impact Resistance Index (325 ± 23.07), and compressive strength (29.39 ± 1.82 Nmm⁻²). It would generate much heat and fracture less and could be suitable for use in the Metallurgical Industry. The great VM from all the carbonized woods (18.66 ± 0.73% to 51.91 ± 0.49%) also makes them best suited for outdoor use (e.g., barbecue-making). As they possess varied properties, their intended uses should be guided by their properties for improved performance.

摘要

木炭是一种脆性的黑色碳残渣，由纤维素材料的碳化产生，用作能源。其特性因木材碳化而异。它经常被使用，不管预期的目的和木材碳化。然而，为了客观利用，对来自加纳阿夫拉姆平原的六种广泛使用的木材的碳化木材的近似和强度特性进行了调查。碳化木材的水分含量符合推荐标准。因此，在正常大气条件下几乎不会改变。它们的堆积密度范围为 497.39 ± 3.13 kgm ^-3 ( Azadirachta indica ) 至 680.50 ± 8.58 kgm ^-3 ( V. paradoxa )。E. ivorense木炭产生的挥发性物质（VM）最少（18.66 ± 0.73%），灰分（1.94 ± 0.04%），热值高（28208.45 ± 743.72 kJkg ^-1），固定碳含量最高（73.13 ± 0.69%），影响阻力指数 (325 ± 23.07) 和抗压强度 (29.39 ± 1.82 Nmm ^-2 )。它产生的热量多，断裂少，适合在冶金工业中使用。来自所有碳化木的巨大 VM（18.66 ± 0.73% 至 51.91 ± 0.49%）也使它们最适合户外使用（例如，烧烤）。由于它们具有不同的特性，因此它们的预期用途应以其特性为指导，以提高性能。
