Pyrolysis Of Biomass

Due to the rapid growth of energy consumption, fossil-based fuel is at the verge of extinction. Hence, the world needs new energy to substitute for the non-renewable energy resources. Various biomass resources have been discussed by virtue of the ability of generating alternative fuels, chemicals and energy-related products. To date, the utilization of biomass is mainly thermochemical conversion which involves combustion, gasification and pyrolysis. The focus, currently, is on the catalytic pyrolysis of biomass. A variety of reactors are designed and many new catalysts for the yields of liquid products and upgrading of bio-oil are investigated. Different reactors have their own unique characteristics, and fixed bed reactor is not complicated and can be controlled easily but is difficult to upsize. Fluidized bed has a good suitability for different kinds of biomass but is more complex in structure and more difficult to control. Compared with non-catalytic pyrolysis, the quality of bio-oil improves considerably in the presence of a catalyst. Different catalysts exert different effects on the upgrading of bio-oil. HZSM-5 can reduce a vast output of acid compounds and increases hydrocarbon yields. Au/Al2O3 catalyst leads to an increase of H2 yield. All the catalysts can promote the upgrading of pyrolysis products. Optimal yields and the best quality of bio-oil can be obtained by an appropriate reactor with a proper catalyst.

<p>Pyrolysis properties of fresh ficus lacor leaves with moisture content of 70<em>wt</em>. % was investigated in a TGA setup. The effects of different operating parameters on pyrolysis of biomass were studied in a fixed-bed reactor system. With addition of CaO, there showed an additional decrease in weight at temperature range of 382~490 <sup>o</sup>C, but 12<em>wt</em>. % weight was recovered in the first stage (40~220 <sup>o</sup>C). Fresh biomass pyrolysis was calculated to be first order reaction with activation energy about 29.8 kJ mol<sup>-1</sup>. Activation energy was lowered to 20.4 kJ mol<sup>-1</sup> by addition of CaO. With scope of temperature studied, higher temperature was found always favor hydrogen production during pyrolysis of fresh biomass. Carbonation and hydration of CaO enhanced water gas shift reaction (WGS) which led to hydrogen yield increasing. The highest hydrogen content (around 70<em>vol</em>. %) of hydrogen concentration and hydrogen yield (23.2 ml g<sup>-1</sup><sub>-biomass</sub>) were achieved when CaO/biomass mass ratio increased to 0.3. Pyrolysis of fresh biomass without pre-drying showed the potential of hydrogen production.</p>

Steam gasification of biochar from catalytic pyrolysis of biomass was studied in a fixed bed reactor at atmospheric pressure. The experiments were carried out at bed temperature of 700, 750, 800 °C at steam flow rate of 0.1 g/min with reaction time of 3h. The gases produced included mainly H2, CO, CO2 and some small molecular hydrocarbons. The results showed that high gasification temperature was favorable for the production of hydrogen-rich gases. The maximum concentration of hydrogen exceeded 85% at 800 °C and the total gas yield increased with temperature rising. Meanwhile, the conversion efficiency of biochar at 700, 750, 800 °C was 48%, 60%, 72% respectively.
