【正文】 產品質量之間的內在聯(lián)系，這些研究對開發(fā)和優(yōu)化渣油加工技術、調整工藝條件、制定合理的加工方案，具有重要的指導作用。 Sulfur was detected by ultraviolet fluorimetry, nitrogen by chemiluminescence. Those information and data they offered can provide necessary data for further study on group position and chemical position.The results show that heteroatom concentrates in heavier ponent. Sulfur mainly concentrates in aromatics and resins of eight ponents. Sulfur content is highest in heavy aromatics and light resins of eight ponents. Nitrogen content increases in evidence in heavy aromatics, and is highest in heavy resins. Residue fixedbed hydrotreating is one of the most effectively means of residue oil hydroprocessing. The effectiveness of the conversion of residue oil into more value products depends upon the careful evaluation of residue oil position and property, prehensive study of the relation of feedstock and products and the selection of appropriate conversion process.Key words: Residue；Hydrotreating；Eight ponents；Removal rate目錄一 引言 概述………………………………………………………………………………1二 渣油加氫產物對比簡介 渣油原料的主要特點…………………………………………………………2 渣油加氫的發(fā)展背景…………………………………………………………3 渣油加氫處理的主要化學反應………………………………………………5 渣油及其生成油性質表征國內外研究進展…………………………………13 本課題的研究方向及應用價值………………………………………………14三 實驗部分 實驗樣品、試劑和實驗儀器…………………………………………………16 渣油的分離……………………………………………………………………17 渣油的性質表征………………………………………………………………19四、結果與討論……………………………………………………………………33五、參考文獻………………………………………………………………………37一、概述近年來，隨著能源危機的日益加劇，原油變劣、變重，輕質油品的需求日益增加以及環(huán)保要求越來越嚴格等多種因素的影響，渣油的利用越來越被人們所重視，渣油深度轉化也成為煉油廠長期追求的目標。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。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、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)。兩種工藝條件下渣油加氫產物對比研究[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。結果表明：硫、氮和金屬等雜原子主要集中在較重的組分中。 [關鍵詞]：渣油；加氫；八組分；脫除率 Comparative study of the product of residue hydrotreating by two different processesTong Beizhen0902石油化工AbstractCooperating with FRIPP working on development of residue fixedbed hydrotreating technologies, various postprocessing oils were obtained by two different processes, and the physical and chemical properties of the postprocessing oils were investigated to pare the processes. The eight ponents were saturates, light aromatics, middle aromatics, heavy aromatics, light resins, middle resins, heavy resins and asphaltene separately. These separation schemes could quantify the ponents, and prepare for later the help of modern instruments, the information of the position and physical chemistry properties of the samples were provided. Metal content was determined by ICPAES。如何深度加工產量日益增長的重質原油和其中的大量高硫減壓渣油，以滿足經濟發(fā)展對清潔燃料和低硫
