    • This process for converting a charge of heavy oils or petroleum residues to gaseous and distillable hydrocarbons comprises the steps of (a) admixing said charge with a first hydrogenated recycle oil obtained in a subsequent step of the process, heating the mixture to 350.degree.-450.degree. C., admixing it with a reducing gas at a temperature of at least 800.degree. C. and maintaining a temperature of 530.degree.-850.degree. C. and a pressure of at least 20 bars for 0.1 to 60 seconds (b) admixing the resultant product with a second hydrogenated recycle oil whose temperature is lower than 300.degree. C., thereby decreasing the temperature of the resultant mixture to less than 450.degree. C., then contacting it with a steam-hydrogen stream, thereby vaporizing at least 80% of the liquid to a gaseous phase (c) treating the unvaporized remaining fraction with oxygen and steam to form a reducing gas at a temperature of at least 800.degree. C., used at least partly in step (a), (d) hydrogenating the gaseous phase from step (b) and recovering therefrom a light fraction distilling below 250.degree. C., recycling at least partly the remaining gaseous phase to step (b) after removal of CO.sub.2 and H.sub.2 S therefrom and (e) recycling the remaining hydrogenated heavy oil fraction, distilling above 250.degree. C., to steps (a) and (b).
    • 用于将重油或石油残余物转化成气态和可馏出烃的方法包括以下步骤:(a)将所述电荷与在该方法的后续步骤中获得的第一氢化循环油混合,将混合物加热至350-450℃ 将其与还原气体在至少800℃的温度下混合并保持530-850℃的温度和至少20巴的压力进行0.1至60秒(b)将 得到的产物具有温度低于300℃的第二氢化循环油,从而将所得混合物的温度降低至低于450℃,然后使其与蒸汽 - 氢气流接触,从而汽化至少80% (c)用氧气和蒸汽处理未蒸发的剩余馏分以在至少800℃的温度下形成还原气体,至少部分地在步骤(a)中使用,(d)将 来自ste的气相 p(b)并从其中回收低于250℃蒸馏的轻馏分,在从其中除去CO 2和H 2 S之后将至少部分剩余的气相再循环至步骤(b),和(e)回收剩余的氢化重油馏分,蒸馏 高于250℃,步骤(a)和(b)。
