PROCESS FOR OBTAINING BENZENE, TOLUENE (AND NAPHTHALENE) FROM C1-C4-ALKANES WITH CO-DOSAGE OF HYDROGEN OF A SEPERATE LOCATION

PROCESS FOR OBTAINING BENZENE, TOLUENE (AND NAPHTHALENE) FROM C1-C4-ALKANES WITH CO-DOSAGE OF HYDROGEN OF A SEPERATE LOCATION

The present invention relates to a process for nonoxidatively dehydroaromatizing a reactant stream comprising C1-C4-aliphatics by converting the reactant stream in the presence of a catalyst in a reaction zone 1 to a product stream P comprising aromatic hydrocarbons, and regenerating the catalyst wh...

Zusammenfassung:The present invention relates to a process for nonoxidatively dehydroaromatizing a reactant stream comprising C1-C4-aliphatics by converting the reactant stream in the presence of a catalyst in a reaction zone 1 to a product stream P comprising aromatic hydrocarbons, and regenerating the catalyst whose activity has been reduced by deposited coke with a hydrogen-comprising mixture H in a reaction zone 2, wherein at least a portion of the deposited coke is converted to methane and at least a portion of the methane formed is fed to reaction zone 1.
