Abstract A natural hydrogen donor, i.e., a subfraction of the coker gas oil, was used in thermal upgrading of the Venezuela extra-heavy oil. The role of hydrogen donor was quantitatively studied by a combination of thermogravimetric analysis and differential scanning calorimetry. The hydrogen donation was clearly evidenced and reliably evaluated by comparing the experimental and calculated thermal parameters. The mutual interactions between the heavy oil and the hydrogen donor extended the coke induction period (from 19 to 25 min), inhibited the thermal evaporation of the hydrogen donor, and resulted in a stronger endothermic effect in the pyrolysis stage.

委内瑞拉超重油的氢供热热升级:确定氢供体的作用
摘要 采用天然氢供体,即焦化瓦斯油的亚馏分,用于委内瑞拉特重油的热改质。氢供体的作用通过热重分析和差示扫描量热法的组合进行定量研究。通过比较实验和计算的热参数,可以清楚地证明并可靠地评估供氢。稠油与供氢体之间的相互作用延长了焦炭诱导期(19~25 min),抑制了供氢体的热蒸发,导致热解阶段吸热效应更强。
