The article discusses the thermal polycondensation methods of petroleum pitch production. The main attention is paid to the characteristics of petroleum pitch, its properties, and its comparison with coal-tar pitch. It describes three promising petroleum pitch production technologies, namely, thermal polycondensation of cracking residue, high-temperature thermal polycondensation of petroleum stock, and two-stage thermal polycondensation of pyrolysis tar. Methods of petroleum pitch production under laboratory conditions, such as thermal polycondensation under pressure and thermal treatment at low pressure, are proposed. The urgency and expediency of promotion of petroleum pitch production and introduction of thermal polycondensation process in Russia are underscored.

文章讨论了石油沥青生产的热缩聚方法。主要关注石油沥青的特性、性质以及与煤焦油沥青的比较。介绍了裂解渣热缩聚、石油原料高温热缩聚和热解焦油两段热缩聚三种有前景的石油沥青生产技术。提出了在实验室条件下生产石油沥青的方法，例如加压热缩聚和低压热处理。强调了在俄罗斯推广石油沥青生产和引入热缩聚工艺的紧迫性和权宜之计。
