    摘要: The present invention relates to a process for producing microcellulose comprising hydrolyzing fibrous cellulosic material with an acid at an elevated temperature or acidifying fibrous cellulosic material followed by washing and hydrolyzing the washed cellulosic material at an elevated temperature to produce a microcellulose-hydrolysate mixture followed by separation of the microcellulose from the hydrolysate, wherein the mixture or separated hydrolysate or microcellulose is optionally neutralized, and wherein the microcellulose production is integrated to production of a pulp mill such that at least part of chemicals used in the acidification, acid hydrolysis and/or neutralization is produced by an integrated chemical recovery process of the pulp mill.
