摘要
获得了对富马酸吸附量大选择性好的活性炭ＳＢ，解决了Ｌ苹果酸生产中富马酸的分离，循环使用性能稳定。
Fumaric acid adsorption during the L malic acid production is discussed. It is shown that the activated carbon SB can absorb fumaric acid specifically and efficiently. The content of fumaric acid in L malic acid after being adsorbed by the absorbent is down to 0.1%. The effect of flow rate on the adsorption, selection of the regenerating agent and recycling stability of the adsorbent are also discussed. The experiment shows that this method for reducing the content of fumaric acid in L malic acid is suitable for the application in the production of L malic acid.
