<description><![CDATA[As the inferior fuel, black liquor needs the process assistance of concentration and combustion-supporting in the traditional alkali recovery system, which has the problems of high energy consumption, low thermal efficiency and sulfur oxide emission. In this work, the weak black liquor of kraft pulping was studied. Organic small molecule components and lignin were separated from black liquor, alkali was recovered based on organic pretreatment and catalytic electrolysis in this study. Then, lignin was depolymerized into hydrocarbon fuel to improve the fuel properties of black liquor. The results showed that the calorific value of black liquor upgraded fuel was 35.14MJ/kg, which was increased by 133.02% by comparing with that of the original black liquor. The temperature corresponding to the maximum combustion rate was 123.52℃, the maximum combustion rate was 10.82 %/min. The combustion characteristic index was much higher than that of black liquor and other biomass oils, indicating that the black liquor upgraded fuel has high flammability. Moreover, low apparent activation energy (23.36 kJ/mol) and high pre-exponential factor (2.68*106 min-1) indicated that the black liquor upgraded fuel is more easily to ignite and burn. This study contributes to the energy-saving and efficiency improvement of black liquor utilization, helps enterprises reduce production costs, and provides technical references for the production and utilization of renewable energy.]]></description>

<title><![CDATA[Advances in Deep Eutectic Solvents as Efficient Pretreatment for Lignocellulose Biorefinery]]></title>
<link><![CDATA[http://zgzz.ijournals.cn/zgzzen/ch/reader/view_abstract.aspx?file_no=202008060000001&flag=2]]></link>
<description><![CDATA[Deep eutectic solvents (DES),as one of emerging class of green solvents, exhibits easy availability, low cost, biocompatibility, recyclability, strong molecular polarity and designability.These features make it attractive in wild applications including biorefinery, catalysis, biomass conversion and functional materials manufacturing. Therefore, based on the recent research reports on lignocellulose biorefinery with DES, this review mainly focuses on the dissolution mechanism, influencing factors and separation effect of cellulose, hemicellulose and lignin by using different types of DESs alone or combing other assistant treatments. The advantages, disadvantages and current situation of the functionalization and high-value utilization of DES- fractionated components are also discussed, so that it can provide some new insights/ inspirations for the comprehensive and efficient utilization of DES in lignocellulose biorefinery.]]></description>
