Abstract

The invention provides an oil sand pyrolysis dry distillation method. The method comprises the following steps of: performing dry distillation by using oil sands and coal as raw materials to obtain dry distillation gas and semi-coke; and treating the dry distillation gas to obtain light oil, mixed oil and fuel gas. According to the oil sand pyrolysis dry distillation method provided by the invention, oil sands and coal are used as raw materials to perform a dry distillation reaction, so that the output of fuel gas can be increased; and the produced fuel gas is recycled in the dry distillation of oil sands and coal, so that enough heat can be obtained in the dry distillation process, and an extra heat source is not required.

Description

technical field [0001] The invention belongs to the technical field of energy utilization, and in particular relates to an oil sand pyrolysis dry distillation method. Background technique [0002] With the continuous increase of global oil demand, conventional oil resources can no longer meet the rapid growth of oil demand, people began to turn their attention to unconventional oil resources. As the main source of unconventional oil resources, oil sands have been increasing in proportion to the global available hydrocarbon energy in recent years, playing a pivotal role in the world's energy supply, and are an important replacement resource for future oil and gas resources. Oil sand refers to the sandstone impregnated with heavy residual oil that has been exposed or near the surface. It is the product of asphalt-based crude oil that loses light components during the migration process, and sometimes refers to a natural product that is impregnated and partially escaped from lig...
