Abstract: Rational development and utilization of biomass research has attracted a widely attention in recent years,but how to make use of its resources is a hot issue to be resolved. Currently,the catalytic processes for lignocellulose degradation are diversity,recent research progress at home and abroad for various solid acid catalyst in degradation of cellulose was described in this paper,the merits as well as drawbacks of these method were analyzed in catalytic degradation of cellulose from different aspects.Among these solid acid,the nano metal oxide has a better prospect. The process of catalytic degradation of cellulose through solid acid is complicated,with a variety of resulting factors,to realize industrial application of this method needs further study.
