Then quality upgrading scheme was explored in order to solve the high content of sulphur and nitrogen in pyrolytic oil, low flash point as well. Yields of pyrolysis of scrap tires in a pilot-scale rotary kiln under 550℃were firstly summarized. Then elemental composition and physiochemical properties were analyzed on both pyrolytic crude oil and its fractions. Based on these researches, the feasibility that pyrolytic oil is used as fuel was discussed. From FT-IR spectra the functional group compounds were generally acquainted, and by column chromatography analysis chemical compositions were clearly known. Then through GC analysis the absolute content of BTX in pyrolytic crude oil was defined.

White wax scale contained 7.2% crude polysaccharide. The polysaccharide content was 4.54% after removing protein by enzyme. The sugar content of the polysaccharide was 22.1% as glucose, composed of glucose, galactose and fructose in molar ratio of 5:21:1. The polysaccharide isolating from white wax scale was polysaccharide-protein complex. This insect contained 1.3% flavonoid and several kinds of vitamins.

分析結(jié)果表明：白蠟蟲含有2.14%甲殼素色色综合电影网站；7.2%的粗多糖久久婷婷国产麻豆91天堂，除蛋白后的多糖含量4.54%，多糖含量以葡萄糖計(jì)為28.4%国产精品黄片在线播放，由葡萄糖亚洲福利日韩看片无码、甘露糖和果糖組成，3種糖的摩爾比為5：21：1久操手机在线网站播放，白蠟蟲多糖為一種雜多糖－蛋白復(fù)合物一级做a爱全免费视频在线；白蠟蟲還含有1.3%的總黃酮和多種維生素。

Thirdly, by con-utilaziont of many methods such as exploitation and geology, dynamic producing process monitoring, water invasion behavior, core analyis and numerical simulation, 10 kinds of reservoir scale remaining oil distribution pattern in the steam huff and puff super heavy crude oil reservoir was put forward. Also, remainling oil distribution in the sand bed scale and sublayer scale were pointed out.Fourthly, Microcosmic displacement experiment was conducted for hot water driving in 100℃and 120℃. and steam drive at 170℃condition. Microcosmic remaining oil distribution characteristics were summarized. Remaining oil microcosmic distribution by steam drive at 170℃is different from that at 100℃, 120℃hot water driving. After the steam drive, there are three types of remaining oil distribute regular pattern, whic is impacted by many affecting factors like pore configuration, wettability and interfacial tension.
