Abstract The objective of the present pee is to install a modified suitable and compatible nuclear reactor trunk for the cost-efficient production of renewable liquid send outside(a) (bio-oil) from agro-based bio-mass. This new type of reactor system contains a combustor attached 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) mark pipe through which hot sand is circulated by th e rive of air pump. Thus, effective heat transfer from the infinitely circulated het up sand as well as efficient biomass transmutation into the reactor can be obtained. In this work, jute adhere and bagasse abundantly available in Bangladesh were pyrolyzed separately in a constant feeding circulating fluidized bed reactor at nigh 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 be higher than the yields obtained from fixed bed pyrolysis reactor. The total yields of kindle arrest were 19.4 wt% and 21.7wt% after complet e pyrolysis of bagasse and jute stick respec! tively, which are less than that of charr 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 pop out a full essay, order it on our website: BestEssayCheap.com
