АННОТАЦИЯ
Amaranthus Retroflexus (AR) or redroot pigweed is a second generation lignocellulosic fuel. Each biomass sample (leaves, inflorescences and stems) was pyrolyzed in a lab-scale furnace, in a ni-trogen atmosphere under non-isothermal conditions at heating rates of 10 °C/min until the furnace temperature reached 550 °C. The pyrolysis characteristics of the three major components were also studied by thermogravimetric analysis (TGA). The thermal decomposition of the studied biomass samples is similar to the process of pyrolysis of lignocellulosic materials and proceeds in three main stages: dehydration, devolatilization, and carbonation. The greater bio-oil yield was ob-tained for inflorescences (55 %) and leaves (45 %). GC-MS analysis was carried out for oil fractions of pyrolysis liquid from AR. The composition of pyrolysis oil fraction from the leaves had an overbearing of aliphatic hydrocarbons nature whereas oil fraction from inflorescences and stems were composed mainly of oxygen - containing components. The use of AR biochars can lead to slag formation in power equipment, so it is advisable to use them to produce composite fuel, for example, mixed with coal. The results would help further understanding of thermal behavior of AR biomass and its utilization for fuels or chemicals.
