Exploring the Prospective of Weed Amaranthus retroflexus for Biofuel Production through Pyrolysis

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