Abstract
The presently disclosed subject matter relates to torrefied biomass briquettes and methods for producing the same that make use of a mixture of lightly torrefied material (LTM) and highly torrefied material (HTM) and/or make use of torrefied materials that are subjected to a hydrolysis pretreatment prior to being torrefied.
Claims27
A torrefied biomass briquette, comprising:
- (a) about 10% to about 95% of a highly-torrefied material (HTM) and about 5% to about 90% of a lightly torrefied material (LTM);
- (b) a torrefied acid hydrolyzed biomass having a FTIR profile comprising one or more reduced oxygen functionalities as compared to biomass not subjected to acid hydrolysis;
- or
- (c) a combination of (a) and (b).
A method of producing a torrefied biomass briquette, comprising:
- producing a mixture comprising about 10% to about 95% of a highly-torrefied material (HTM) and about 5% to about 90% of a lightly torrefied material (LTM);
- preheating the mixture to a predetermined temperature;
- compressing and simultaneously heating the mixture
A method of producing a torrefied biomass, comprising:
- providing an amount of a biomass;
- subjecting the biomass to an acid hydrolysis to produce a hydrolyzed biomass;
- and
- torrefying the hydrolyzed biomass.
A biomass briquette, comprising an acid hydrolyzed biomass having a FTIR profile comprising one or more reduced oxygen functionalities as compared to biomass not subjected to acid hydrolysis.
