這一工作包括：為標定有機質成油、成氣的化學動力學模型，設計進行了恆速升溫熱模擬實驗；為標定油成氣的化學動力學模型，設計進行了等溫的油裂解成氣的熱模擬實驗；為建立油中各族組分（飽和烴、芳烴、非烴、瀝青質）成氣的化學動力學模型，進行了恆溫或恆速升溫模擬實驗。The typical deep viscous oils in loujia - kenxi area are characterized by a high density ( or low api gravity ), a high viscosity, a high sulfur content and low amounts of saturates and aromatics as compared to resins and asphaltenes
羅家-墾西地區的典型稠油在物性上具有高密度、高粘度和高凝固點等特點。在化學組成上具有含硫量高、膠質和瀝青質含量高，而飽和烴、芳烴含量低。We are an integrated supplier of paraffin wax, slack wax, bitumen, base oil, rpo, white oil, liquid paraffin and aromatics products, like propylene, dop and other petrochemical products
主要產品包括：各種石蠟、瀝青、基礎油、橡膠操作油、液體石蠟、白油以及芳烴類產品，丙烯、二辛脂等。Officers attached to the district crime squad of kwai tsing and the customs and excise department mounted the operation at 8 am today. they raided three premises and six locations in the district including tai wo hau, kwai fong, kwai hing and tai lin pai industrial area, resulting in the seizure of 300 sticks of contraband cigarettes and 350 litres of illicit petrol and the arrest of three men aged between 15 and 21
葵青警區重案組及海關人員於今早八時採取行動，突擊搜查大窩口、葵芳、葵興、大連排工業區共三個單位及六處地點，共檢獲三百支冒牌香煙及三百五十公升非法燃油，並拘捕三名年齡介乎十五至二十一歲的男子。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
在層析分析的基礎上，將焦油分為五部分：脂肪烴、芳香烴、酯類、極性物、瀝青質。應用gc ms對焦油的成份進行了分析和比較。One set of composition analysis method was erected for biomass gasification tar, in which tar samples are separated into aliphatics, aromatics, ester, polar and aspheltenes fractions of increased polarity by one kind of chromatography, and gc / ms is used for the characterization of each fraction except aspheltenes
層析將焦油樣品分離為脂肪類、芳香類、酯類、極性物、瀝青質五個不同極性的族分，然後再對各族分採用gc - ms分別進行定性和定量分析，並最終獲得焦油的主要組成信息。分享友人
