Performance evaluation of pyrolysis reactor for soybean crop residue
Author(s): GH Wasu and SR Kalbande
Abstract: Pyrolysis is the one of the best the technique for production of bio-oil from agricultural crop residues. It is one of the alternatives to replace fossil fuels with the help of feed stocks. Bio-oils may be shipped, stored and utilized much like conventional liquid fuels once their specific fuel properties are taken into account. The soybean crop residue was selected for carrying out research work. Biomass particle size plays an important role during the design of bio-oil reactor and recovery of bio-oil. It was suitable for satisfying the condition of fast pyrolysis. The screw conveyor feeding method was used to feed the raw material in reactor chamber. Temperature throughout reactor was not same. It varies according to height and also with the distance from wall of the reactor chamber. In temperature profile of reactor, it was found that temperature at middle region of reactor chamber was higher than that of top and bottom regions of reactor chamber. The performance of pyrolysis reactor was taken at different temperature of 450, 500, 550 and 600 oC respectively at that time feeding rate of pyrolysis unit was kept constant i.e. 1 kg/h. The maximum recovery of bio-oil from soybean crop residues was found as 11 (wt.) % at temperature of 550 oC. The highest recovery of bio-char was found 40 (wt.) % at temperature of 450 oC. The highest yield of NCG + Bio-oil was estimated 28.5 % at temperature of 600 oC.
