Utilization of Kraft lignin is a complex challenge and effective approaches to its solution have not yet been found. One of the promising ways in this area is the processing of lignin into syn-gas and carbon residue, which can be used to obtain sorbents. Processing of lignin into synthesis gas by dry reforming (LDR) under the action of MWI allows for the efficient processing of large-scale waste - lignin and carbon dioxide into an important product of petroleum chemistry like syn-gas with a selectivity exceeding 90%. MWI on the one hand is the source of heat in the reaction volume, on the other hand its effect leads to an increase in the vibrations of the substrate molecules and their polarization, which significantly increases the intensity of the release of hydrogen from the lignin compared to convective heating. Graphite-like conversion of carbon is a valuable raw material for the production of porous carbon sorbents for the treatment of industrial wastewater. It is followed by the fact that it has been measured that it has reached 0.5-0.8 nm. In the case of heat treatment, it is recommended that you follow the short-term heat treatment.
