摘要

本文的目的是对冷杉属和松属初加工的副产物进行化学评价，以确定将其用作固体生物燃料的可能性。灰分、挥发性物质和固定碳值通过近似分析确定。基本化学成分包括提取物含量、木质素和全纤维素的测定。用X射线光谱仪进行灰分微量分析，并用AC600量热计测定样品的热值。本研究的结果如下：无机物含量（0.33%-0.41%）、挥发性物质含量（88.54%-82.57%）、固定碳含量（11.13%-17.06%）、提取物含量（5.37%-17.82%）、Runkel木质素含量（27.33%-30.97%）、全纤维素含量（58.53%-69.56%）和热值（19.09MJ·kg-1-20.42MJ·kg-1）。根据X射线分析，最丰富的元素是钾、钙和镁；而没有发现重金属。这项研究的结果表明，这里研究的两个属适合生产固体生物燃料。

Chemical Composition and Energy Evaluation of Abies spp. and Pinus spp. Sawdust Collected as a Byproduct of the Primary Wood Sawing

The aim of this paper is to chemically evaluate the byproducts of the primary processing of genera Abies and Pinus, to determine the possibility of using them as solid biofuel. Ash percentage, volatile matter and fixed carbon values were determined by proximate analysis. The basic chemical composition includes the determination of extractives content, lignin and holocellulose. Ash microanalysis was performed with an X-ray spectrometer and the calorific value of the samples was determined by using an AC600 calorimeter. The results of this research varied as follows: the content of inorganic substances (0.33% to 0.41%), volatile matter (88.54% to 82.57%), fixed carbon (11.13% to 17.06%), extractives content (5.37% to 17.82%), Runkel lignin (27.33% to 30.97%), holocellulose content (58.53% to 69.56%) and calorific value (19.09 MJ·kg-1 to 20.42 MJ·kg-1). According to the X-ray analysis, the most abundant elements were potassium, calcium and magnesium; whereas no heavy metals were found. The results of this research show that the two genera studied here are suitable for solid biofuel production.

期刊介绍： The primary aim of the SEEFOR journal is to publish original, novel and quality articles and thus contribute to the development of scientific, research, operational and other activities in the field of forestry. Besides scientific, the objectives of the SEEFOR are educational and informative as well. SEEFOR should stimulate intensive professional and academic work, teaching, as well as physical cooperation of institutions and interdisciplinary collaboration, a faster ascendance and affirmation of young scientific personnel. SEEFOR should contribute to the stronger cooperation between the science, practice and society, and to the overall dissemination of the forestry way-of thinking. The scope of the journal’s interests encompasses all ecological, economical, technical, technological, social and other aspects of forestry and wood technology. The journal is open for publishing research from all geographical zones and study locations, whether they are conducted in natural forests, plantations or urban environments, as long as methods used in the research and obtained results are of high interest and importance to South-east European and international forestry.
