Abstract
Embodiments presented herein describe an apparatus and method to control the conversion of carbonaceous materials, particularly biomass and those biomass resources, into a high performance solid fuel. This method, and the apparatus described as the means to accomplish this method, provides a process having a control system that enables the system to produce a fuel of uniform quality, even with a change in biomass supply.
Claims25
A method for the continuous torrefaction of biomass to obtain a fuel of specified or constant properties, said method comprising:
- sensing a property of biomass;
- and
- controlling the torrefaction in proportion to said property,
- wherein said sensing senses a mid-infrared spectra of torrefied biomass, and wherein said controlling includes utilizing a correlation of mid-infrared spectra and two ratios of H, C, and O atoms to estimate, based on said correlation and said sensed spectra, two ratios of H, C, and O atoms in the sample, and changing torrefaction parameters to approach the target values of H, C, and O atoms.
A method for the continuous torrefaction of biomass to obtain a fuel of specified or constant properties, said method comprising:
- sensing a property of the biomass during the torrefaction of the biomass;
- and
- controlling the torrefaction in proportion to said property.
