The performance of the microcrystalline cellulose (MCC) is dependent on the feedstock. In this work, two MCC samples were prepared from two softwood pulps under the same technological conditions. The particle size and distribution, fluidity, crystallinity and micromorphology of the two MCC samples were compared with those of the imported MCC product. The results showed that the size and size distribution of MCC produced by Masson pine were similar to those of imported MCC, while the MCC from imported softwood presented smaller diameter and more narrow distribution. The imported MCC showed best fluidiy. XRD analysis showed that the MCC obtained by Masson Pine had highest crystallinity, followed by imported microcrystalline cellulose and the MCC prepared from imported softwood wood. The MCC produced by the coniferous wood had a flaky structure, while the imported MCC had sturdier morphology and better fluidity.
