Co-Processing Kraft Lignin And Pyrolysis Oil: An Efficient Method for Suppressing Char Formation
Short Introductive summary
Co-processing of Kraft lignin and pyrolysis oil have been performed using catalytic reductive liquefication with hydrothermally synthesized unsupported NiMoS catalyst. Interestingly, for the first time, we were able to show that the addition of pyrolysis oil during Kraft lignin depolymerization could completely suppress the char formation. In order to further understand the reason for this beneficial effect were multiple model compounds investigated and it was found that 4-propylguaiacol was efficient as char suppressing agent.
