A method for the valorization of an organic solid biomass feedstock for liquid fuel and/or chemical productions, the method comprising:
- introducing an organic solid biomass feedstock into within a reaction zone of a methanolysis reaction system in the presence of a methane-containing gas and a methanolysis catalyst structure so as to convert the solid organic feedstock, via methanolysis, to a liquid bio-oil product and a synthetic gas product;
- and
- introducing the synthetic gas product into a liquefaction reaction system in the presence of a second gas and a liquefaction catalyst structure so as to convert the synthetic gas product, via liquefaction, to a liquid oil product.
A method of forming a methanolysis catalyst structure, the method comprising:
- dissolving two or more metal salts in water to form a metal precursor solution comprising any two or more metals selected from the group consisting of Mo, Ni, Co, Ag, Ga, Ce, and Zn;
- loading the metal precursor solution into a porous support structure;
- drying the porous support structure loaded with metal precursor for a period of at least 2 hours at a temperature from about 80° C. to about 120° C.;
- and
- calcining the dried support structure loaded with metal precursor in a gas atmosphere and at a temperature ranging from about 300° C. to about 700° C. and at a heating rate ranging from about 5° C./min to about 20° C./min to form the methanolysis catalyst structure.
A method of forming a liquefaction catalyst structure, the method comprising:
- dissolving two metal salts in water to form a mixed metal precursor solution;
- introducing an alkaline solution as a precipitation agent to the mixed metal precursor solution in a dropwise manner under agitation to form a slurry;
- aging the slurry at a temperature from about 25° C. to about 28° C. for at least 12 hours;
- repeatedly washing and filtering the aged slurry to form resulting precipitates, followed by drying the resulting precipitates at about 90° C. to about 105° C. for a time period from about 6 hours to about 12 hours to form a dried support structure;
- calcining the dried support structure at 550° C. for 3 hours under static air to form a mixed metal oxide support structure;
- dissolving a single alkali metal salt in water to form a metal precursor solution;
- loading the metal precursor solution into the mixed metal oxide support structure;
- drying the mixed metal oxide support structure loaded with the metal precursor for a period of at least 2 hours and at a temperature from about 80° C. to about 120° C. to form a dried catalyst structure loaded with a single alkali metal;
- and
- calcining the dried catalyst structure loaded with the single alkali metal in a gas atmosphere and at a temperature ranging from about 300° C. to about 700° C. and at a heating rate ranging from about 5° C./min to about 20° C./min to form the liquefaction catalyst structure.
A method of forming a liquefied fuel oil product, the method comprising:
- providing a synthetic gas as an input to a mixed bed reactor including a plurality of liquefaction catalyst structures;
- liquefying the syngas to yield a liquefied fuel oil product and a gaseous product;
- and
- separating the liquefied fuel oil product from the gaseous product.
