本发明介绍了一种在超临界条件下从硅藻土申提取碳氢化合物的方法,该方法比采用Fischer干馏法从沥青砂中回收碳氢化合物有明显的改进。本发明还论述了硅藻土在超临界条件下的提取方法和设备。
The present invention describes a process for the extraction of hydrocarbons from diatomaceous earth under supercritical conditions that provides a significant improvement over the recovery of hydrocarbons from tar sands using Fischer dry distillation. The present invention also discusses a method and apparatus for extracting diatomaceous earth under supercritical conditions.
