The present invention relates to a method of preparing a mesoporous carbon material with layered structure using humin. The preparation method provided by the present invention may prepare a mesoporous carbon with layered structure, especially a mesoporous carbon with layered structure having a regular frame. Prepared by the present invention, the mesoporous carbon with layered structure having the regular frame has a specific surface area up to 1000 m/g and an average pore diameter of 3 nm-6 nm. Such method solves the present problems of low use efficiency of humin and severe waste of resources.

The present invention relates to a method of preparing n-butyric acid by using poly-3-hydroxybutyrate. The method comprises following steps: placing poly-3-hydroxybutyrate in a closure means, passing hydrogen into the closure means to eliminate air after making an initial hydrogen pressure be 2 to 6 MPa, carrying out an agitation at 190 to 240&#xb0; C. for reaction for 6 to 36 hours to obtain n-butyric acid. The preparation method provided by the present invention does not require a catalyst or a reaction solvent, and converts poly-3-hydroxybutyrate into n-butyric acid by a one-step reaction under a hydrogen atmosphere. The conversion rate of poly-3-hydroxybutyrate is 100%, the yield of n-butyric acid reaches up to 97%, the purity of n-butyric acid in all obtained liquid products reaches up to 98%, and no additional subsequent separation process is needed to the target product n-butyric acid.
