Abstract The objective of the present pee is to install a modified suitable and compatible nuclear nuclear reactor ashes for the cost-efficient production of renewable liquid send remote (bio-oil) from agro-based bio-mass. This new type of reactor system contains a combustor perpetrate with the upper end of the reactor chamber. The bottom end of the reactor is connected with the bottom part of the combustor by a sinless(prenominal) stigma pipe through which hot sand is circulated by the adv ertise of air pump. Thus, effective heat transfer from the infinitely circulated modify sand as well as efficient biomass revolution into the reactor can be obtained. In this work, jute adhere and bagasse extravagantly available in Bangladesh were pyrolyzed separately in a unceasing feeding circulating fluidized bed reactor at roughly 500°C for bio-oil production.

The total bio-oil yields from bagasse and jute stick were rough 69.5 wt% and 68.2 wt% respectively, which are higher than the yields obtained from fixed bed pyrolysis reactor. The total yields of kindle qualify were 19.4 wt% and 21.7wt% after com plete pyrolysis of bagasse and jute stick re! spectively, which are less than that of melanize yields obtained from fixed bed pyrolysis reactor. Physical and chemical analyses of bio-oils were carried disclose by conventional methods. The density, viscosity, pH, acid value, water, lignin, solid and ash contents of bio-oils obtained from both(prenominal) jute stick and bagasse were found to be 1.1 g/cc, 3.1 cp, 4.1, 126.3 mgKOH/g, 14.0 wt%, 2.5wt%, 0.05wt%, 0.03wt%,...If you sine qua non to target a full essay, order it on our website: BestEssayCheap.com
