Abstract This invention relates to the use of an Explosion Process Reactor for the production of high crystallinity, low DP and narrow DP distribution Cellulose, for value added conversion of the Cellulose component of the Dissociated Lignocellulosic starting material to a range of grades of Cellulose Triacetate having different Degrees of Purity, Reactivity and Polymerization. The first few steps in the process produce a standard bleached Cellulose product, which can then be post bleach treated in a number of different ways dependent on end product requirements to produce a range of celluloses having varying degrees of polymerization, purity, reactivity and crystallinity, in a mercerized (Cellulose II) or unmercerized (Cellulose I) form for value added conversion to Cellulose Triacetate. These same post bleach treatments can be used to prepare Cellulose for a wide range of other value added conversions and uses.
