Abstract The objective of the present pee is to install a modified suitable and compatible nuclear reactor administration for the cost-efficient production of renewable liquid send out (bio-oil) from agro-based bio-mass. This new type of reactor system contains a combustor committed 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 circul ated by the pound of air pump. Thus, effective heat transfer from the infinitely circulated het up sand as well as efficient biomass conversion into the reactor can be obtained. In this work, jute adhere and bagasse profusely available in Bangladesh were pyrolyzed separately in a sustained feeding circulating fluidized bed reactor at nearly 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 abridge were 19.4 wt% and 21.7wt% after compl ete pyrolysis of bagasse and jute stick resp! ectively, which are less than that of kindle 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 some(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 grow a full essay, order it on our website: OrderCustomPaper.com
