中文摘要:采用锐钛矿型二氧化钛对两种硫酸盐黑液半焦在860℃的温度下进行了直接苛化与水蒸气气化实验。结果表明:黑液半焦中的有机碳可在6min内气化完毕,直接苛化反应也可在此时间内完成;气化所得气体的干基高位热值约10MJ/m3;气化与直接苛化所得固体产物熔点高于900℃且粉末状态良好,主要成分为五钛酸钠,该产物水解后生成氢氧化钠和不易继续水解的三钛酸钠;回收的三钛酸钠继续用于直接苛化实验时,固体产物没有发生结块现象,可以循环利用;约占黑液总硫20%的硫以非还原态留存于气化残余固体中。

Abstract:Steam gasification of kraft black liquor char was performed at 860℃ in a tube furnace with direct causticization using anatase titanium dioxide and recycled sodium tri-titanate. The organic carbon in the black liquor char could be completely gasified within 6 min, approximately equal to the complete conversion time of sodium carbonate in black liquor char to sodium penta-titanate at these conditions, and the generated dry gas had a high heating value of nearly 10MJ/m3. The main component of solid product was sodium penta-titanate, and the sodium tri-titanate recycled from hydrolysis of sodium penta-titanate had satisfactory reactivity compared to fresh titanium dioxide. No agglomeration of solid product was observed through the process of reactions. About 20% of total sulfur in black liquor retained in the gasified residual solid in the form of non-reduced state.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
