Abstract
Embodiments of methods and apparatuses for producing an aromatic hydrocarbon-containing effluent are provided herein. The method comprises the step of rapidly heating a biomass-based feedstock to a first predetermined temperature of from about 300 to about 650° C. in the presence of a catalyst, hydrogen, and an organic solvent within a time period of about 20 minutes or less to form the aromatic hydrocarbon-containing effluent. The biomass-based feedstock comprises lignocellulosic material, lignin, or a combination thereof.
Claims17
A method for producing an aromatic hydrocarbon-rich effluent, the method comprising the step of:
- heating a biomass-based feedstock to a first predetermined temperature of from about 300 to about 650° C. in the presence of a catalyst, hydrogen, and an organic solvent within a time period of about 1 second to about 5 minutes to form the aromatic hydrocarbon-containing effluent, wherein the biomass-based feedstock comprises lignocellulosic material, lignin, or a combination thereof;
- and
- extracting aromatic hydrocarbons from the aromatic hydrocarbon-containing effluent to form the aromatic hydrocarbon-rich effluent.
A method for producing an aromatic hydrocarbon-rich effluent, the method comprising the steps of:
- heating a first quantity of a biomass-based feedstock in a reactor to a first predetermined temperature of from about 300 to about 600° C. in the presence of a catalyst, hydrogen, and an organic solvent within a first time period of about 1 second to about 5 minutes to form a first quantity of the aromatic hydrocarbon-containing effluent, wherein the biomass-based feedstock comprises lignocellulosic material, lignin, or a combination thereof;
- removing the first quantity of the aromatic hydrocarbon-containing effluent from the reactor;
- recycling at least a portion of the first quantity of the aromatic hydrocarbon-containing effluent back to the reactor;
- heating a second quantity of the biomass-based feedstock in the reactor to the first predetermined temperature in the presence of the catalyst, hydrogen, and the at least the portion of the first quantity of the aromatic hydrocarbon-containing effluent within a second time period of about 1 second to about 5 minutes to form a second quantity of the aromatic hydrocarbon-containing effluent;
- and
- extracting aromatic hydrocarbons from the aromatic hydrocarbon-containing effluent to form the aromatic hydrocarbon-rich effluent after the step of removing and prior to the step of recycling.
