Abstract

This study investigates the impact of a water-soluble aquathermolysis catalyst on the highly viscous oil from the Boca de Jaruco field (Republic of Cuba) and presents an analysis of laboratory findings. The most efficient water-soluble catalyst, based on nickel sulfate, was identified for enhancing the physicochemical properties of the viscous oil. The paper also provides recommendations for selecting the appropriate temperature conditions during steam-thermal treatment, along with the optimal concentration of nickel sulfate (0.4 % wt.). It was revealed that the mass concentration of asphaltenes in the oil decreased by 50 % in the presence of nickel sulfate compared to the original oil. Additionally, the saturated fraction increased by 70 % compared to the initial oil and by 30 % relative to the control experiment. Furthermore, the sulfur content in the oil was reduced from 5.9% to 5.4 % during thermal steam treatment (TST) when nickel sulfate catalyst and a hydrogen donor were used.

热蒸汽处理过程中高粘度油升级用催化水溶性组合物的研制

本研究调查了水溶性水热裂解催化剂对Boca de Jaruco油田（古巴共和国）高粘性油的影响，并对实验室结果进行了分析。以硫酸镍为基料的水溶性催化剂对提高稠油的理化性能最有效。本文还提供了在蒸汽热处理过程中选择适当温度条件的建议，以及硫酸镍的最佳浓度（0.4% wt.）。结果表明，与原油相比，在硫酸镍的存在下，油中沥青质的质量浓度降低了50%。此外，饱和分数比初始油增加了70%，比对照实验增加了30%。此外，使用硫酸镍催化剂和氢供体进行热蒸汽处理（TST）时，油中的硫含量从5.9%降至5.4%。
