1、I兩種工藝條件下渣油加氫產(chǎn)物對比研究 兩種工藝條件下渣油加氫產(chǎn)物對比研究郭靖蘭州交通大學摘 要本課題配合撫順石油化工研究院渣油加氫處理技術開發(fā)工作，針對同一渣油經(jīng)兩種加氫工藝加工后的生成油，進行物化性質和八組分分離等研究。即將原料油及加氫處理油的正庚烷可溶物進入色譜柱分離，得到飽和烴、輕芳烴、中芳烴、重芳烴、輕膠質、中膠質、重膠質和瀝青質八組分。借助元素分析儀、化學熒光定硫儀、化學發(fā)光定氮儀等對原料油、加氫處理油及八組分的氫、碳、硫、

2、氮含量、金屬含量等性質進行測定，給出原料油及加氫生成油組成的詳細信息，為比較兩種工藝的優(yōu)缺點、催化劑選擇、工藝流程選擇等提供依據(jù)。結果表明：硫、氮和金屬等雜原子主要集中在較重的組分中。硫主要集中在芳烴和膠質組分中，其中重芳烴和輕膠質中硫的含量最高，重芳烴中氮含量較前幾個組分明顯增多，重膠質氮含量最高。研究結果還表明：在脫金屬段，工藝 A 的脫釩和脫鎳程度都比工藝 B 要大，工藝 A 的脫釩、脫鎳效果更佳；在脫硫、氮段，硫、氮的脫除率工藝

3、 B 明顯高于工藝 A，工藝 B 的脫硫、氮效果更佳。渣油固定床加氫處理是合理利用渣油的最為有效的手段之一。渣油轉化為更有價值的產(chǎn)物取決于對其組成和性質的認識，以及原料油與加氫處理油之間的關聯(lián)關系的研究和轉化工藝的選擇。IIIComparative study of the product of residue hydrotreating by two different processesTong Beizhen（Industry A
