摘要

Recently, hydrothermal carbonization method (HTC) has been proposed for the production of biochars that could be part of a new pathway for activated carbon production from biomass, and especially from lignocellulosic precursors. In HTC, carbonaceous precursors are converted into valuable carbon materials by submitting them to low temperatures (180-220 °C) and using water as the carbonization medium under self-generated pressure, which saves energy and renders a green synthesis procedure1. In order to introduce porosity in the lignocellulosic biomass derived HTC carbons, post-synthesis methods are required. One of the most frequent activations for biomass wastes employs H3PO4 as the porogen agent, which favors the cyclation and aromatic condensation reactions of the hydrocarbon components of biomass, rendering a higher carbonization yield, while inducing the generation of a wide pore size distribution (PSD) through the insertion of phosphorus bridges2. In this work, H3PO4-assisted HTC using different lignocellulosic biomass as the raw materials is proposed for the production of low cost activated carbons.
