摘要
沥青质是原油和渣油中缔合性最强的组分,沥青质容易通过电荷转移、氢键、偶极相互作用等聚集。当外界条件或成分改变时,沥青质可能会聚集和聚沉,造成设备堵塞和损坏,因此给石油产业带来了挑战。沥青质分散剂可以有效地抑制沥青质的聚沉。从沥青质的结构、分散剂的种类和分散机理等方面综述了沥青质分散剂的研究进展,并且对沥青质分散剂的发展趋势进行了分析。
Asphaltene is the most associative component in crude oil and residual oil.Asphaltene can easily aggregate with each other through charge transfer,hydrogen bond and dipole interaction.Asphaltene may congregate and settle when external conditions or composition change,which poses a challenge to the petroleum industry.Asphaltene dispersants can effectively inhibit the agglomeration of asphaltene.In this paper,the research progress of asphaltene dispersants is reviewed from the aspects of asphaltene structure,dispersant types and dispersant mechanism,and the future development trend of asphaltene dispersants is analyzed.
