Abstract:

Methods of transforming a hydrocarbon feedstream into an aromatization product in a multi-stage reverse flow reactor (RFR) apparatus are disclosed. The methods include at least two reaction stages in series, at least one being a pyrolysis stage and at least another being a catalytic aromatization stage. Using a highly saturated hydrocarbon feedstream the pyrolysis stage focuses on desaturation, while the catalytic aromatization stage focuses on aromatization. The catalytic aromatization stage contains a aromatization catalyst that can include substantially no magnesium, scandium, yttrium, titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, manganese, rhenium, iron, ruthenium, cobalt, rhodium, nickel, palladium, platinum, copper, silver, gold, gallium, indium, tin, lanthanides, or actinides, or, in some cases, substantially no added active metals at all. The aromatization product can contain at least 35 mol % aromatic hydrocarbons, based on a total amount of hydrogen and hydrocarbons in the aromatized hydrocarbon product.
