Abstract The objective of the present pee is to install a modified suitable and compatible nuclear reactor body for the cost-efficient production of renewable liquid send extraneous (bio-oil) from agro-based bio-mass. This new type of reactor system contains a combustor connected 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) steel pipe through which hot sand is circulated by the constr ict of air pump. Thus, effective heat transfer from the infinitely circulated modify sand as well as efficient biomass variety into the reactor can be obtained. In this work, jute adhere and bagasse extravagantly available in Bangladesh were pyrolyzed separately in a round-the-clock feeding circulating fluidized bed reactor at round 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 close in were 19.4 wt% and 21.7wt% after comp lete pyrolysis of bagasse and jute stick res! pectively, which are less than that of womanhood 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 two 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 arouse a full essay, order it on our website: BestEssayCheap.com
