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 onward (bio-oil) from agro-based bio-mass. This new type of reactor system contains a combustor pull 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) brace pipe through which hot sand is circulated by the for te of air pump. Thus, effective heat transfer from the infinitely circulated het up(p) sand as well as efficient biomass reincarnation into the reactor can be obtained. In this work, jute adhere and bagasse richly available in Bangladesh were pyrolyzed separately in a never-ending feeding circulating fluidized bed reactor at most 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 argon higher than the yields obtained from fixed bed pyrolysis reactor. The total yields of kindle confine were 19.4 wt% and 21.7wt% after comple te pyrolysis of bagasse and jute stick respe! ctively, which are less than that of flame 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 ticktock a full essay, order it on our website: BestEssayCheap.com
