Thermogravimetric Analyzer

Stone coal and two kinds of biomass were respectively mixed and studied during pyrolysis by using thermogravimetric analyzer. The results showed that the main pyrolysis peak temperature of stone coal is the lowest under the mixing ratio of 3:7 during the pyrolysis process. Because of the high content of alkali, corn stalk has better promotion for the coal pyrolysis compared to sawdust.

The pyrolysis behaviors of cotton stalk, corn stalk and corn cob have been investigated with the thermogaravimetric ananlysis(TGA) coupled with Fourier transform infrared spectrometer(FTIR). The results from TGA show that there are two reaction stages in the pyrolysis process, corn cob is easier to decomposition than others at the same temperature, and their pyrolysis process is different from each other. Different chemical component ratio maybe link with the variable biomass pyrolysis behaviors. The corn cob yield the most organic compound for its highest content of cellulose and the cotton stalk yield the most non-condensable gas in addition to H2 for its highest content of hemicellulose from the integrated data of peak area. Thus, the content of cellulose and hemicellulose have an important role in the biomass pyrolisis.

Abstract The developed Ni-La/Al2O3-CeO2-Bamboo charcoal (ACB) catalyst was applied to the co-pyrolysis of straw and plastic to produce hydrogen in a horizontal quartz tube pyrolysis furnace. In this study, the effects of the mixing ratio of straw and plastic, the presence and stability of the catalyst on the co-pyrolysis hydrogen production were investigated. Experiment showed that the addition of PE can increase the yield of H2 within a certain range, and the best mass ratio of 5:5 was found. In the co-pyrolysis process with the participation of the catalysts, the macromolecular tar can be cracked into combustible gases such as H2, and the H2 yield could be increased to 332.2ml/g (Ni-La/ACB) is much higher than 68.87ml/g without catalyst. Compared with Ni/ACB, Ni-La/ACB had been increased the alkalinity by adding La element and enhanced the carbon deposition resistance of the catalyst, which makes the catalyst maintain higher stability. This was also confirmed in stability test experiments.

In order to understand the behavior of biomass pyrolysis, a series of pretreatment biomass were prepared with acid-washing and metal impregnated methods. The effects of metal ions on the yields of tar, char and gas from straw pyrolysis were analyzed in our lab scale fixed-bed reactor. Alkali metal and alkaline earth metal ions affect biomass pyrolysis process and the products heavily. The decreasing metal ions result in declining yield of semi-char and increasing yields of tar and gas. Meanwhile, the pyrolysis temperature corresponding maxium yield of tar increases. There exist marked catalytic effect of potassium, calcium and magnesium cations on the cracking of large molecular weight parts of tar and semi-char formation via recombination reaction of tar. As cause a higher production of char while a decrease of tar and gas production.

To find out the Co-pyrolysis characteristics of Dianchi Lake sludge and coal,Dianchi Lake sludge was introduced into coal pyrolysis process. In this paper,the pyrolysis experiments of Dianchi Lake sludge and coal were carried out by TG and TGA. Results show that the TG and DTG profiles of Dianchi Lake sludge were similar to coal, but different from coal under various blending ratios.Interaction was observed between the solid phases of Dianchi Lake sludge. The results provide a reference for further study on co-pyrolysis of Dianchi Lake sludge and coal to a certain extent.
