Pyrolysis is a process by which oils are generated for the production of fuels. This process also produces waste water that contains phenolic water-soluble compounds. Treatment of this waste water with a bio-based adsorbent that can be recycled within the biorefinery is of high interest due to the lack of waste created during treatment. Fibrous biomass, such as pretreated kenaf, can be pyrolyzed with the biomass feedstock to obtain higher BTU values. Along with the use of carbon black as the industrial standard, a variety of pretreatments were explored, including fine ground, course ground, water-rinsed, ozonated, and torrefied. The reuse of spent kenaf allows for the reduced cost of treatment of plant effluent waters and recovery of value added compounds. This produces an environmentally friendly discharge of clean water that can be reused in the process along with the recycled kenaf.
