Low Temperature Pyrolysis Characteristics of Oil Sludge under Various Heating Conditions

This paper presents a comparative description of traditional methods of neutralization and disposal of oilcontaining waste. The basic methods used for these purposes are effective, but they are not without significant drawbacks. In this regard, there is a need to find new ways that will be environmentally friendly and cost-effective. As such methods, low-temperature pyrolysis at the TPU 1 installation, purification of oil-contaminated sludge using solar energy, as well as complex purification of oil sludge were proposed. Their main advantages are compliance with modern environmental standards and the formation of products that can be used in the future as a result of cleaning. It was concluded that it is appropriate to use each of the proposed methods depending on the amount of contamination.

Low Temperature Pyrolysis

The utilization of high moisture, high volatile low rank coals such as lignite is gaining importance day by day to meet the growing demands of coal for the energy sectors. For the combustion of pulverized material it appears essential to dry lignite. Further, lowest possible ash and moisture as well as high heat content are desired for combustion. The present work gives the details of the preparation of a product of higher calorific value by thermal treatment of Inner Mongolia lignite. The low-temperature pyrolysis characteristics were carried out on the regularities of pyrolysis temperature and holding time on the product yield of dry distillation of lignite by using aluminium retort method. The result shows that the suitable pyrolysis condition of lignite is 450 ~ 510 °C, holding time for 30 min. The ratio of aliphatic and aromatic groups of 400°C semi-coke obviously decrease 53.1% and 11.8% compared with raw coal. The degree of aromatization of semi-coke is gradually increased and aromatic nucleus condensation degree increases. The retort process of lignite is a dehydrogenation, deoxidization and carbon-rich process.

The pyrolysis characteristics for two types biomass material was tested at 230°C~250°C, and the pyrolysis product component was on-line analyzed by using moisture micro-detection teller, gas chromatograph-mass spectrometer computer and fourier transform infrared spectroscopy. Besides, two different algorithms were used to evaluate the test error. In addition, the generated tar gas was secondary decomposed at 800°C. It is found that the tar was broken up completely, which increased the hydrogen content sharply in the pyrolysis gas. The test data shows that the heat value of cotton stalk improves better than that of the corn stalk after pyrolysis, so it is more suitable for cotton stalk than corn stalk to improve the value in use by means of low temperature pyrolysis technology.
