The gas chromatographic method of high-temperature simulated distillation (HTSD) is described, and the results are presented for the application of HTSD to the characterization of petroleum refinery feed and products from solvent deasphalting operations. Results are presented for refinery residual feed, deasphalted oil, and asphaltene fractions from the residual oil supercritical extraction process. Asphaltene removal from petroleum residuum using solvent deasphalting results in the improved quality and high recovery of deasphalted oil product for use as lube oil, fluid catalytic cracking, or hydrocracker feedstocks. The HTSD procedure presented here proves valuable for characterizing the fractions from the deasphalting process to obtain the percentage yield with boiling point data over the range from approximately 36 degrees C (97 degrees F) to 733 degrees C (1352 degrees F), which covers the boiling range of n-paraffins of carbon number C5 to C108.
描述了高温模拟蒸馏（HTSD）的气相色谱方法，并给出了HTSD在石油炼制原料和溶剂脱沥青操作产品表征中的应用结果。给出了炼厂渣油原料、脱沥青油以及渣油超临界萃取过程中沥青质馏分的结果。使用溶剂脱沥青从石油渣油中去除沥青质可提高脱沥青油产品的质量，并实现高回收率，该产品可用作润滑油、流化催化裂化或加氢裂化原料。本文介绍的HTSD程序对于表征脱沥青过程中的馏分很有价值，可获得沸点数据在约36℃（97℉）至733℃（1352℉）范围内的产率百分比，该范围涵盖了碳数为C5至C108的正构烷烃的沸点范围。
