Abstract
An energy efficient process for converting biomass into a higher carbon content, high energy density slurry. Water and biomass are mixed at a temperature and under a pressure that are much lower than in prior processes, but under a non-oxidative gas, which enables a stable slurry to be obtained containing up to 60% solids by weight, 20-40% carbon by weight, in the slurry. The temperature is nominally about 200° C. under non-oxidative gas pressure of about 150 psi, conditions that are substantially less stringent than those required by the prior art. In another embodiment, the biomass water slurry can be mixed with a coal water slurry to further optimize the carbon content and pumpability of the biomass slurry.
