摘要(Abstract)：

在超临界溶剂脱沥青装置上,以辽河稠油减渣为原料,得到脱沥青油的同时,用PGSS法直接对脱油沥青进行造粒实验。在压力为5.0～7.0MPa、温度为150～165℃的范围内考察了操作参数、喷嘴结构、脱油沥青性质对所得沥青颗粒分布的影响。压力增加、温度减小,50～100目沥青颗粒的质量分数增大,50目、40目、30目沥青颗粒质量分数减小,其中50～100目沥青颗粒的质量分数大于66%。喷嘴长度由13mm增加到40mm、内径由2.0mm减小到1.0mm,50～100目沥青颗粒的质量分数增大,50目、40目、30目沥青颗粒质量分数减小。压力增加、温度减小,脱油沥青的软化点增大。沥青性质的变化导致了沥青颗粒分布的变化。扫描电镜分析结果表明,所得沥青颗粒为不规则的多孔性物质,沥青颗粒的范围主要在50～100目。
