Properties of sugarcane waste-derived bio-oils obtained by fixed-bed fire-tube heating pyrolysis.

Mohammad Rofiqul Islam; Momtaz Parveen; Hiroyuki Haniu

Agricultural waste in the form of sugarcane bagasse was pyrolyzed in a fixed-bed fire-tube heating reactor under different pyrolysis conditions to determine the role of final temperature, sweeping gas flow rate and feed size on the product yields. Final temperature range studied was between 375 and 575 degrees C and the highest liquid product yield was obtained at 475 degrees C. Liquid products obtained under the most suitable conditions were characterized by physical properties, elemental analysis, GCV, FT-IR, (1)H NMR analysis and distillation. The empirical formula of the bio-oil with heating value of 23.5MJ/kg was established as CH(1.68)O(0.557)N(0.012). Comparison with other approaches showed that the liquid product yield by this simpler reactor system was higher with better physico-chemical properties as fuel. These findings show that fixed-bed fire-tube heating pyrolysis is a good option for production of bio-oils from biomass solid wastes.

In this research, a development and performance test of a fixed-bed batch type pyrolysis reactor for pilot scale pyrolysis oil production was successfully completed. The characteristics of the pyrolysis oil were compared to other experimental results. A solid horizontal condenser, a burner for furnace heating and a reactor shield were designed. Due to the pilot scale pyrolytic oil production encountered numerous problems during the plants operation. This fixed-bed batch type pyrolysis reactor method will demonstrate the energy saving concept of solid waste tire by creating energy stability. From this experiment, product yields (wt. %) for liquid or pyrolytic oil were 49%, char 38.3 % and pyrolytic gas 12.7% with an operation running time of 185 minutes.

The objective of this study is to provide an innovation in pyrolysis technology to the recovery of liquid hydrocarbons from biomass solid wastes. A fixed-bed fire-tube heating pyrolysis reactor system has been designed and fabricated considering all of the process parameters and present engineers challenge. The available agricultural waste-jute stick in Bangladesh has been pyrolyzed in the internally heated fire-tube heating reactor system under N2 atmosphere. The effects of operating temperature on the yields of product liquids were investigated. Characterization of the whole pyrolysis liquids obtained at optimum operating conditions has been carried out including physical properties, elemental analyses and GCV. The results show that fixed-bed fire-tube heating pyrolysis is a good option to obtain bio-oils from biomass solid wastes.
