Catalytic composition and application to the conversion of synthesis gas to a mixture of hydrocarbons having a high content of aromatic compounds

摘要

Improved catalytic compositions, which can be used especially in the Fischer-Tropsch process, which comprise: a. At least one Fischer-Tropsch catalyst; b. Optionally at least one promoter of the Fischer-Tropsch catalyst; c. At least one zeolite, cocatalyst of the Fischer-Tropsch catalyst. These compositions additionally comprise at least one agent for protecting the zeolite.
