hydrocarbon content
1.The morphological structure of DJ-9073b extended by the 4th vaccum side-distillate oil ( alkane content is higher and aromatic hydrocarbon content is 67.91% ) was more uniform and compact than that of DJ-9073a extended by the low alkane content oil.
2.When the rubber was extended with 37. 5phr high aro- matic hydrocarbon content oil, the rheological properties of S-SBR and the surface of ex- truded rubber were even much better.
3.Some proposals are put forward including concentrated regeneration of rich solution and treating tail gas by SCOT process, decreasing hydrocarbon content in acid gases and carryover and condensing of hydrocarbons in dry gas, strengthening solution strain, selective absorption and upgrading pressure of acid gas feeding in sulphur recovery plants, improving gas preheating in sulphur recovery plants and degassing liquid sulphur.
4.The hydrocarbon generation content in Lower Cambrian and Lower Silurian is up to 60%~80% of total.
5.The results indicated that, carbon content of coal to yields of liquid hydrocarbon, H/C of coal to yields of gas hydrocarbon and oxygen content of coal to yields of CO、CO 2 and H 2O show close corresponding relations.
6.ANALYZING REQUIREMENTS & EFFECT OF ACIDOLYSIS HYDROCARBON IN HIGH CARBONATE CONTENT SOIL
7.Presented in this study are the characteristics of aromatic hydrocarbon biomarkers in the Lower Palaeozoic marine carbonate rocks in North China, including phenanthrene, biphengl, benznuorene,benzfhiore tri-fluorene, fluoranthene series pyrene, benz fluoranthene series beamperylene, chrysene and triaromatic sterane. The content of naphthalene is relatively low.
8.Comparing the parameters such as distribution of carbon amount,carbon amount with peak value of content,carbon predominance index(CPI),and pristane/phytane ratio(Pr/Ph) in the immature organic matters in the sediments from the bottom of Qinghai Lake with those in mature hydrocarbon source rocks and crude oils from the typical salty lacustrine environment in our country can give us a set of valuable reference data about the maturity of organic matters.
