SYSTEM AND METHOD FOR PURIFYING PROCESS WATER PRODUCED FROM BIOMASS CONVERSION TO FUELS

摘要

In accordance with one embodiment, a process is described for a water treatment process in which water produced from a fuel production process is treated with recycled biochar. In accordance with one aspect, process water is passed through activated carbon generated by the biomass pyrolysis and gasification. In accordance with another aspect, the process water is treated to expel gaseous compounds within the process water. In this manner both inorganics, light organics and heavy organics can be removed from the process water. No fermentation is involved.

主权项

1. A method for removing contaminants from process water produced during biomass conversion to fuels comprising:
pyrolyzing biomass to produce gaseous compounds and biochar; gasifying the biochar from the pyrolysis process to create an adsorptive medium; passing the gaseous compounds to a fuel production process to create fuel and process water, wherein the process water contains one or more of organic cont contaminants or particulate contaminants; and treating the resulting process water by passing the process water through the adsorptive medium to remove one or more of organic contaminants, inorganic contaminants or particulate contaminants to produce treated process water.
