FRACTIONS DISTRIBUTION AND ELEMENTAL COMPOSITION OF HEAVY OILS BY PYROANALYSIS

ABSTRACT

Oxidative pyroanalysis apparatus was settled to fully characterize heavy oils. Fractions distribution, and elemental composition were obtained in one single run on both volatile and non volatile fractions. Correlation between experimental Carbon residue values and Conradson carbon residue data is possible and a crackability index of the heaviest part of heavy oil is determined. From all gathered data, quality of products can be appreciated in these circumstances as well as thermal sensitivity resulting in accurate determination of conversion indices.

Vitrification of a waste water flocculate from a petroleum catalyst manufacturer

Chemical and mineral compositions of a waste water flocculate generated in a manufacturer producing fluidized-bed catalytic cracking catalysts were analyzed. The flocculate was then calcined at 1200–1350 °C. X-ray diffraction analysis results indicate that the flocculate can be directly vitrified at 1350 °C without the addition of any other ingredients. The density and chemical durability of the directly vitrified product are comparable with commercial soda-lime-silicate glasses. However, the viscosity of directly vitrified glass melt was very high. Thus, the refining and shaping of the glass melt were difficult. With the addition of minerals such as limestone, dolomite and fluorite, workable glasses could be formed. The influence of MgO on the structure and properties of the obtained glasses is discussed. Results show that the density and hardness of the glass increase with the increase of MgO, whereas the chemical durability, transition and crystallization temperatures decrease. The present study provides a general way to utilize waste water flocculates in glass production.

光催化深度净化处理染料废水

采用絮凝初级处理与光催化深度净化复合的方法处理染料皂黄废水,研究絮凝剂PAC用量、TiO2用量、反应时间等因素对皂黄处理效果的影响。实验结果表明,絮凝剂用量增加到一定程度时,皂黄的脱色率几乎不变;光催化单独作用可以使染料完全脱色,但需要较长的反应时间。在100 mL皂黄溶液中,当絮凝剂用量为50 mg,TiO2用量为5.0 mg,反应进行到10 min时皂黄的脱色率就达到76.1%。絮凝-光催化复合方式处理染料皂黄大大提高了脱色效率。
