摘　　要：本文采用了一种基于数值计算的稳态模拟方法,结合实验获取的重质油加氢脱硫实验数据和模型假设,使用数学模型进行“正、逆问题”求解。通过对重油加氢实例的研究,首先实现了重质油加氢脱硫模型的建立,进而基于实验数据求解了稳态模拟的“逆问题”;其次又基于所建立模型及拟合得到的参数完成了稳态模型“正问题”的求解。“正、逆问题”的求解逻辑,不仅是一种有效的科研手段,更是一项脱胎于工程实际案例的教学素材。通过深入探讨重油加氢实例,并结合正、逆问题求解方法,我们可以为学生提供更全面、系统的化工知识和能力培养。This article adopts a numerical simulation method based on steady-state calculations,combining experimental data obtained from heavy oil hydrodesulfurization experiments with model assumptions.Mathematical models are used to solve the“direct and inverse problems”.Through the study of an example of heavy oil hydroprocessing,the establishment of a model for heavy oil hydrodesulfurization is achieved,followed by solving the“inverse problem”of steady-state simulation based on experimental data.Subsequently,the solution to the“direct problem”of the steady-state model is obtained using the established model and fitted parameters.The logic behind solving the“direct and inverse problems”not only serves as an effective scientific research method but also provides teaching material rooted in practical engineering cases.By delving into heavy oil hydroprocessing examples and combining direct and inverse problem-solving methods,we can provide students with a more comprehensive and systematic chemical engineering knowledge and skill development.
