| 1. | Study on the dispersion characteristics of asphaltenes in different solvents 石油沥青质胶体分散特性的研究 |
| 2. | Petroleum produvts . determination of asphaltenes precipitated by normal heptane 石油产品.用标准正庚烷测定沉淀沥青 |
| 3. | Test method for determination of asphaltenes heptane insolubles , in crude petroleum and petroleum products 原油和原油产品沥青物质测定方法 |
| 4. | Testing of petroleum products - determination of the content of asphaltenes - precipitation with heptane 石油产品的试验.沥青烯含量测定.庚烷沉淀 |
| 5. | Methods of test for petroleum and its products - determination of asphaltenes heptane insolubles in crude petroleum and petroleum products 石油及其产品的试验方法.原油和石油产品中沥青烯 |
| 6. | A certain mounts of asphaltenes always occur with bc particles were produced from the incomplete combustion of biomass or fossil fuels 在燃烧过程中碳黑沥青质总是伴随着碳黑产生,并与碳黑结合在一起。 |
| 7. | Characterization of fresh bc and asphaltenes show that fresh bc structurally rigid and physically condensed . and different to graphite , bc contains a little aliphatic groups and oxygen - containing groups 但现代碳黑又不同于石墨,它还具有一些含氧官能团、脂珠江三角洲地区土壤和表层沉积有机质的非均质性研究肪碳等结构。 |
| 8. | Reactions incorporating nitrogen and phosphorus into the asphaltenes are particularly significant at a time when the effects on the environment of many materials containing these elements are receiving considerable attention 将氮气和磷混合成沥青的化学反应尤为重要,因为含有这些元素的物质对环境造成的影响正受到严重关注。 |
| 9. | G ) the analysis of the tar content with the aid of gc / ms ; before the analysis by the gc / ms , a lot of pre - treatment was done to divide the tar into five part : aliphatics , aromatics , ester , polar , asphaltenes 在层析分析的基础上,将焦油分为五部分:脂肪烃、芳香烃、酯类、极性物、沥青质。应用gc ms对焦油的成份进行了分析和比较。 |
| 10. | Except the asphaltenes , the other 4 part was given to the gc / ms . h ) comparison of gas contents and flow rate before and after the catalytic cracking reaction ; i ) the energy cost of the catalytic cracking ; after the exper 在此基础上,结合热裂解和催化裂解的反应理论解释了生物质焦油的催化裂解原理,同时分析了催化裂解和热裂解前后气体成份和含量的变化。 |
