摘要： Methods are provided for converting lignin-containing biomass into compounds that are more readily processed to form fuel and/or chemical products. The methods can allow for removal of at least a portion of the oxygen in lignin, either during or after depolymerization of lignin to single ring aromatic compounds, while optionally reducing or minimizing aromatic saturation performed on the aromatic compounds. The methods can include use of quench solvent to control reactions within the product stream from a pyrolysis process and/or use of a solvent to assist with hydroprocessing of lignin, lignin-containing biomass, or a pyrolysis oil.

摘要： In a process for producing para-xylene, a feed stream comprising C6+ aromatic hydrocarbons is separated into a toluene-containing stream, a C8 aromatic hydrocarbon-containing stream and a C9+ aromatic hydrocarbon-containing stream. The toluene-containing stream is contacted with a methylating agent to convert toluene to xylenes and produce a methylated effluent stream. Para-xylene is recovered from the C8 aromatic hydrocarbon-containing stream and the methylated effluent stream in a para-xylene recovery section to produce a para-xylene depleted stream, which is then contacted with a xylene isomerization catalyst under liquid phase conditions effective to isomerize xylenes in the para-xylene depleted stream and produce an isomerized stream. The C9+-containing stream with a transalkylation catalyst under conditions effective to convert C9+-aromatics to C8−-aromatics and produce a transalkylated stream, which is recycled together with the isomerized stream to the para-xylene recovery section.

摘要： In a process for producing para-xylene, a feed stream comprising C6+ aromatic hydrocarbons is separated into a C7− aromatic hydrocarbon-containing stream, a C8 aromatic hydrocarbon-containing stream, and a C9+ aromatic hydrocarbon-containing stream. The C7− aromatic hydrocarbon-containing stream is contacted with a methylating agent to convert toluene to xylenes and produce a methylated effluent stream. Ethylbenzene is removed from the C8 aromatic hydrocarbon-containing stream, para-xylene is recovered from the ethylbenzene-depleted C8 aromatic hydrocarbon-containing stream and the methylated effluent stream in a para-xylene recovery section to produce a para-xylene depleted stream, which is then contacted with a xylene isomerization catalyst under liquid phase conditions effective to isomerize xylenes in the para-xylene depleted stream and produce an isomerized stream. The C9+-containing stream with a transalkylation catalyst under conditions effective to convert C9+-aromatics to C8−-aromatics and produce a transalkylated stream, which is recycled together with the isomerized stream to the para-xylene recovery section.

摘要： A process for selectively dealkylating aromatic compounds includes providing a coal tar stream comprising aromatic compounds and hydrotreating the coal tar stream to reduce a concentration of one or more of organic sulfur, nitrogen, and oxygen in the coal tar stream, and to hydrogenate at least a portion of the aromatic compounds in the coal tar stream. The process further includes hydrocracking the hydrotreated coal tar stream to further hydrogenate the aromatic compounds and to crack at least one ring of multi-ring aromatic compounds to form single-ring aromatic compounds. The single-ring aromatic compounds present in the hydrocracked stream are then dealkylated to remove alkyl groups containing two or more carbon atoms.
