Selective Dehydrogenation and Dealkylation Catalyst for Conversion of Light Oil to Benzene
Litol™
Fecha de edición :
febrero 06, 2026
Litol™ is a high-performance catalyst for conversion of light oil, a by-product from the coking of coal, into high-purity benzene. This complex, single-step process achieves desulfurization, removal of paraffins and naphthenes, and saturation of unsaturated compounds, in addition to dealkylation and dehydrogenation. The catalyst operates at lower temperatures than thermal processes, and delivers excellent product purity (benzene content in the end-product exceeding 99.93 wt%). Hence, petrochemical producers attain maximum productivity at minimum costs.
Our complete range of catalysts for dehydrogenation and dealkylation of aromatic hydrocarbons to benzene includes:
Litol™ for light oil to benzene
Detol™ for toluene to benzene
Pyrotol™ for pyrolysis petrol to benzene
Litol, Detol and Pyrotol technologies are exclusively licensed by our process partner, Lummus Technology, while the catalysts are solely produced and supplied by Clariant.
