Abstract

El rendimiento de proceso y transferencia de un reactor para producir celulosa álcali y/o un derivado de celulosa puede incrementarse al utilizar un material basado en celulosa granulada para la preparación de celulosa álcali y/o un derivado de celulosa. Los derivados de celulosa de esencialmente la misma calidad pueden producirse como en los procesos conocidos donde se utiliza material basado en celulosa en polvo para la alcalinización y derivación.
