دراسة بعض الخصائص الفيزيائية و الكيميائية للفحم الخشبي المصنع من عدة أنواع من أشجار الغابات في شمال العراق

Abstract EN

This study was conducted to investigate the suitability of several types of native and nonnative tree woods in Iraq to produce charcoal.

The study was conducted firstly to investigate the contents of woods extraction dissolved in ethanol – benzene, warm water, lignin, Hemicellulose and ash.

Also wood density was measured to show its impact on the quality and quantity of the produced charcoal.

The pyrolysis of wood was conducted, using a laboratory oven at a temperature of 380° C for one hour.

The density, volatile contents, moisture, ash content, analysis of screening and heat of combustion of charcoal were measured as indicators of the produced coal quality.

The results of this study showed that the wood with high density and high lignin content produced coal with good quality and high productivity, compared to the rest of different tested wood types.

The impact of the wood extracts varied, depending on their contents, while Hemicellulose film did not display any obvious effect because of its approximate equal content in the all tested woods
