Abstract

The paper provides experimentally determined thermokinetics of the thermal decomposition of high-viscosity oil (HVO) from the Karazhanbas field, the Republic of Kazakhstan, in the presence of a Fe3O4 nanocatalyst, catalytic additives (nickel catalytic additives in microspheres prepared from coal ash), and polymers (such as polyethylene glycol and polystyrene) as hydrogen donors. The HVO decomposition thermokinetics (activation energy, pre-exponential factor, and rate constants), depending on the presence of nanocatalysts, catalytic additives, and/or polymers, were estimated by thermogravimetry methods in an inert nitrogen atmosphere. The experimental data (including HVO weight loss and weight loss rate vs. temperature) and the estimated thermokinetics of HVO decomposition can be used to create a database appropriate for mathematical modeling of the processing of HVO and heavy oil residues.

存在纳米催化剂,催化添加剂和聚合物的高粘度油分解的基于TGA的热动力学

摘要

本文提供了实验确定的在Fe 3 O 4存在下来自哈萨克斯坦共和国Karazhanbas油田的高粘度油(HVO)热分解的热动力学。纳米催化剂,催化添加剂(由煤灰制备的微球中的镍催化添加剂)和聚合物(例如聚乙二醇和聚苯乙烯)作为氢供体。根据纳米催化剂,催化添加剂和/或聚合物的存在情况,通过热失重法在惰性氮气气氛中估算HVO分解的热动力学(活化能,前指数因子和速率常数)。实验数据(包括HVO失重和失重率与温度的关系)和HVO分解的估计热动力学可用于创建适用于HVO和重油残渣处理数学模型的数据库。
