摘要： A method of retorting oil shale is provided, comprising: continuously feeding oil shale into a retorting unit; heating the retorting unit using renewable electrical energy; converting the oil-shale kerogen into kerogen oil; conveying a cross-flow sweep gas across a moving bed of the oil shale, to carry the kerogen oil out of the retorting unit; recovering the kerogen oil; and recovering spent oil shale. The combination of electrical heating and cross-flow retorting achieves uniform heating to optimize the production of hydrocarbons. A system for retorting oil shale is also provided, comprising: a retorting unit; an inlet for continuously feeding oil shale; electrical-energy elements within the retorting unit; an inlet for conveying a cross-flow sweep gas through the retorting unit; and an outlet for the cross-flow sweep gas carrying the kerogen oil. The principles of the invention may be applied to ex situ systems, in situ systems, or hybrid systems.

摘要： The disclosed technology is a fundamental improvement to existing art for producing valuable products from kerogen ore (oil shale). The disclosure teaches the techniques and benefits of integrating a pyrolysis process with a fluidized catalytic cracking (FCC) unit. Preferred embodiments are based on the use of pyrolysis products from a pyrolysis reactor as feedstock to an FCC unit; within the FCC unit a mixture of high-purity oxygen and carbon dioxide replaces air for coke combustion. To continuously regenerate the FCC catalyst, a coke-oxidation gas contains from 9 mol % to 35 mol % oxygen and from 50 mol % to 90 mol % carbon dioxide. In various embodiments, carbon dioxide is used in place of nitrogen, or used in place of steam, or both of these replacements. Several process configurations are shown, utilizing different recycle schemes and different distillation strategies, among other options. Many valuable co-products are described, including fuels and chemicals.
