重油由于胶质、沥青质含量高,导致黏度较高,造成长距离管输困难。油溶性降黏剂分子可渗入胶质或沥青质分子层之间,起到降低重油黏度的作用。以丙烯酸十八酯、醋酸乙烯酯、马来酸酐、引发剂AIBN为原料,甲苯为溶剂,采用原位合成的方法合成... 详细信息

重油由于胶质、沥青质含量高,导致黏度较高,造成长距离管输困难。油溶性降黏剂分子可渗入胶质或沥青质分子层之间,起到降低重油黏度的作用。以丙烯酸十八酯、醋酸乙烯酯、马来酸酐、引发剂AIBN为原料,甲苯为溶剂,采用原位合成的方法合成SDY-3型油溶性降黏剂。采用委内瑞拉Merey16重油对油溶性降黏剂的性能进行评价,研究了反应单体、反应温度、反应时间、引发剂加剂量对SDY-3型油溶性降黏剂降黏效果的影响。结果表明,在10~50℃温度区间内,当添加降黏剂的质量分数为5%时,降黏率在41.19%~59.47%之间;变剪切速率和定剪切速率实验表明,加入SDY-3型油溶性降黏剂的委内瑞拉重油稳定性较好,降黏剂可用于复杂多变的管输环境。

陈宏谋是清代雍乾时期的能吏,20世纪以来国内外学者对陈宏谋的研究日渐繁盛,亟需做学术综述。学者刘亮红《陈宏谋研究综述》和熊帝兵《陈宏谋研究综述补》等综述文章,对陈宏谋的近现代研究做了全面梳理,然而对陈宏谋自清以降被研习的历史未加详述。实际上,陈宏谋生前身后即被官属、后学们研习,并因时代需求不同,陈宏谋在其研究史中经历了从"18世纪当朝的能吏"到"19世纪的革新家的政治榜样",再到"20世纪道德文化典范"的变化。梳理陈宏谋研究史的转向,是进行陈宏谋深入研究的前提,更是论证其开题价值的基础。
