对稠油沥青质、胶质化学结构的预测和分析有助于石油的炼制和加工.笔者通过Microsoft Visual Studio 2022软件开发的沥青质推测结构工具(SSxAA,Structure speculation and analysis of asphaltenes)是一套可以自动预测稠油沥青质、胶质分子构型的软件.SSxAA借助已有的Brown-Ladner方法,通过软件中设定的结构参数计算、分子构型生成以及合适构型筛选3部分,可以实现仅需输入实验数据便可得到与实验数据相符的稠油沥青质、胶质分子结构构型,再通过分子动力学模拟计算对筛选的结果进行分析,可获得最佳的分子结构.SSxAA已应用于稠油沥青质和胶质平均分子构型的推测,并有望通过后续的更新应用到其他合适的结构分析中.
The prediction and analysis for the chemical structure of asphaltene and resin are helpful to the petroleum refining and processing.As the speculation tool of asphaltene structure(SSxAA,Structure speculation and analysis of asphaltenes)was developed using Microsoft Visual Studio 2022.It is a set of software that can automatically predict the molecular configuration of asphaltene and resin in heavy oil.Based on the existing Brown-Ladner method,by use of the structure parameter calculation module,molecular configuration generation module,and appropriate configuration screening module set in the software,SSxAA can achieve the molecular structure configuration of heavy oil asphaltene and resin consistent with the experimental data only by inputting the experimental data.The best predicted molecular structure can be obtained by analyzing the screening results through molecular dynamics simulation.SSxAA has been applied to predict the average molecular configuration of heavy oil asphaltene and resin,and is expected to be applied to other structural analyses through subsequent updates.
