For TRO there are a little surfacatants whose effect are not good.In this paper,content of sulfonates and composition of alkyl are decided through right design ;under control reaction conditions different alkylbenzene sulfonates are synthesized;Polyreaction catalyst is developed .non-straight high carbon olefine are made through C9-C12 Polyreaction technolgy;clear composition alkylkenzene is sulfanated in falling-film reactor by SO,product can be adjusted,recipe of the surfacate can be used for super-low interfacialtension with Daqing oil -10-3-10-4mN/m,and stablity is good too.According to method issued by Daqing Develop and Explore Research institute,EOR is over 20% in natural core .

本文研究通过烷基苯磺酸盐组成的正确设计,确定了磺酸盐的当量范围和烷基碳数组成和分布;通过对烷基化条件控制,设计合成了不同碳数的直链和支链烷基苯及烷基二甲苯,并用于制备了相应的烷基苯磺酸盐;研制出了新型的烯烃叠合络合催化剂,采用C_9、C_(12)支链烯烃叠合工艺合成了更高碳数的支链烯烃,并进一步合成出相应的烷基苯和烷基二甲苯;以SO_3为磺化剂,通过对磺化条件的选择和控制,采用已知组成的烷基苯混合物进行膜式磺化反应,使合成工艺得以简化;所得磺酸盐组成确定并且可控,最终配方可与大庆原油形成超低界面张力,达10~3~10~(-4)mN/m数量级,且稳定性良好;以合成的烷基苯磺酸盐为主体形成了三元复合驱配方,室内驱油模拟实验表明,按照大庆研究院对复合驱体系活性剂的评价方法,在天然岩芯上的驱油效率在20%以上。

The aniline HDN was strongly stressed by the presence of quinoline and DHQ and the HDN of quinoline proceeds exclusively via a pathway which involves fully saturated intermediates on the MCM-41-supported nickel phosphides. The HDN activity of nickel phosphide catalyst was dramatically reduced by the presence of H2S and DBT, probably due to the strong adsorption of H_2S and DBT on active sites which inhibited the adsorption of quinoline.

喹啉和DHQ对苯胺的HDN反应有强烈的抑制作用,喹啉在磷化镍催化剂上几乎全部通过完全加氢饱和路径进行反应。H_2S和二苯并噻吩强烈地吸附在磷化镍催化剂活性中心上,阻碍了反应物分子的吸附,从而对喹啉的HDN反应有强烈的抑制作用。
