AI Technical Summary

Technical Problem

Existing in-situ conversion catalysts for oil shale suffer from problems such as low catalyst activity, unfriendly organic components to the formation environment, and complex preparation processes, making it difficult to efficiently convert solid organic matter in oil shale.

Method used

A catalyst composed of a Y-type molecular sieve on a support and a lanthanide metal-phytic acid complex was synthesized by treating the mineral support with alkali and mixing it with a silicon source, an aluminum source, seed crystals and inorganic salts. Combined with the lanthanide metal ion complexation reaction, a stable catalyst composite system was formed.

Benefits of technology

It improves the in-situ conversion efficiency of solid organic matter in oil shale, reduces the pyrolysis temperature and activation energy, enhances the stability and activity of the catalyst, and achieves efficient oil and gas generation.
