<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Black liquor lignin mainly exists in the form of solid residues in the biomass pulping process， is a potential feedstock for the production of high-value chemicals. In this study， heteronuclear single quantum coherence nuclear magnetic resonance （HSQC-NMR） was used to characterize the lignin and pyrolysis heavy oil of bamboo kraft black liquor， and the molecular size of the pyrolysis oil fractions of black liquor lignin at high temperature of 600℃ was investigated by quantum chemical calculations. The results showed that the lignin of bamboo kraft black liquor mainly consisted of G-type， S-type and H-type lignin units， and the main components of pyrolysis oil were phenols， ketones， alcohols and ethers. The <i>y</i>-dimension and kinetic diameters of small molecules of pyrolysis oil were mainly concentrated in the region of 6.5~8.4 Å. According to quantum chemical calculations， molecular sieve catalysts with pore sizes in the range of 6.5~8.4 Å could be used for lignin-catalyzed cracking to prepare high-quality liquid fuels.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[At present， the development trend of alkali recovery system is to increase the solid content of black liquor before combustion， computational fluid dynamics （CFD） technology can be used to predict the flow characteristics and atomization combustion performance of black liquor in alkali recovery furnace. The numerical models of black liquor atomization and combustion in alkali recovery system were summaried， research progress of which was emphasized， and the application of isothermal and non-isothermal models in the combustion of black liquor in alkali recovery system was illustrated as well. It is proposed to further improve the model for black liquor combustion and develop a simplified sub-model to realize the accurate numerical simulation for the atomization and combustion of black liquor. It is expected to put forward a new research direction for the black liquor with high solid content in alkali recovery system， and bring up the prospect for the progress and future development of alkali recovery technique.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Bamboo residue was used as raw material to prepare biomass papermaking fillers by biological enzymatic method. The process parameters of bamboo residue fillers prepared by biological enzymatic method and the physicochemical properties of bamboo residue fillers after pretreatment were studied， and the effects of the addition of bamboo residue fillers on the physical strength and wet-end properties of papermaking were investigated. The results showed that the optimum conditions for the preparation of bamboo residue fillers by biological enzyme method were as follows： the amount of biological enzyme was 0.02% （relative to oven-dry bamboo residue）， the pH value was 6.5， the temperature was 65℃， the treatment time was 1 h， and the dissolution of bamboo residue was 6.8% under these conditions. When the content of bamboo residue fillers prepared by biological enzymatic method was 20%， the tensile index and ring compression index of paper were 14.0 N·m/g and 5.79 N·m/g， which were 14.6% and 37.2% higher than that of unfilled paper， respectively. Compared with bamboo residue， the phase structure and thermal stability of bamboo residue fillers prepared by biological enzymatic method did not change significantly， however， the hydrogen bond groups in the macromolecular structure increased and the surface of bamboo residue changed into flakes. The bamboo residue prepared by adding biological enzyme method had no significant effects on the water quality index of papermaking white water.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[China is the first country in the world to use bamboo to produce paper. The origin， development and present status of bamboo papermaking were introduced in this paper. Bamboo papermaking originated in Jin Dynasty of China， it’s handicraft industry developed in Tang and Song Dynasty， and flourished in Ming and Qing Dynasty. Bamboo paper had also made great contributions to social development in modern times. The bamboo pulp and paper industry began after the founding of PRC. Now， bamboo had become an important raw material of China’s paper industry， and bamboo paper had been applied in the field of industry， agriculture， scientific research and daily life， etc. The industry of bamboo pulp and paper in China had been developing very fast in the past years， with the production scale expanded， the cleaner production level improved， and the production benefit increased. Moreover， the development of bamboo pulp and paper industry could alleviate the shortage of papermaking raw materials in China， and promoted the high-quality development of bamboo industry， which had remarkable economic， environmental and social benefits.]]></description>
