A carbon-based solid acid catalyst (CS−SO3H) was prepared by one-step carbonization-sulfonation method from cotton. Under the optimum reaction conditions, the yield of furfural reached 87.3 % from xylose and 63.2 % from corn cob. The reasons for the decline of the catalytic activity were revealed to be the partial leaching of sulfonic acid groups and the accumulation of insoluble humus on the catalyst surface. After regeneration, the activity can be recovered.

用于木糖和玉米芯转化为糠醛的棉花衍生固体酸催化剂
以棉花为原料，采用一步碳化-磺化法制备了碳基固体酸催化剂（CS-SO 3 H）。在最佳反应条件下，木糖糠醛收率为87.3%，玉米芯糠醛收率为63.2%。催化活性下降的原因被揭示为磺酸基团的部分浸出和不溶性腐殖质在催化剂表面的积累。再生后可恢复活性。
