TWO STAGE FIXED-BED CATALYTIC PROCESS FOR UPGRADING PYROLYSIS OIL TO BTX
20250223506 · 2025-07-10 · ·

Systems for upgrading pyrolysis oil include a first fixed-bed reactor having a first catalyst bed and a second catalyst bed. The first catalyst bed includes: a first treating catalyst containing alumina, binder, Mo, Ni, and P; a second treating catalyst made of Al.sub.2O.sub.3, SiO.sub.2, ZrO.sub.2, NiO, and WO.sub.3; or both. The second catalyst bed includes mixed metal oxide catalyst. The first fixed-bed reactor contacts the pyrolysis oil with hydrogen in the presence of the treating catalyst and the mixed metal oxide catalyst to produce an intermediate stream comprising light aromatic compounds. The system includes a second fixed-bed reactor downstream that includes a mesoporous supported metal catalyst having nickel and tungsten on a mesoporous support. The second fixed-bed reactor contacts the intermediate stream with hydrogen in the presence of the mesoporous supported metal catalyst to produce a second reactor effluent comprising aromatic compounds having six to eight carbon atoms.

A PROCESS FOR PRODUCING A LIQUID TRANSPORTATION FUEL COMPONENT

Here is provided processes for producing at least one liquid transportation fuel component. In a first mode of running one of the processes, a hydrocarbon feed including nitrogen impurities is subjected to a hydroprocessing in reactor A in a presence of a hydrotreatment catalyst A to obtain a hydroprocessing effluent A, which is subjected, after degassing, to a catalytic hydroprocessing in reactor B to obtain a hydroteratment effluent B, which is fractionated, optionally after degassing, to obtain at least one liquid transportation fuel component, and/or at least an aviation fuel component. In the process, parameters indicative of deactivation of the hydrotreatment catalyst A are monitored and when these reach predetermined values, the process is switched to a second mode of running wherein the order of reactors A and B is changed so that a degassed hydroprocessing effluent B is fed to the reactor A.
