Abstract
Provided herein is a process for improving the heating value of a cellulosic waste material. The process includes the steps of treating the cellulosic waste material with an acid solution, recovering heat produced by treating the cellulosic waste material, and filtering the treated cellulosic waste material to produce a filter cake. The disclosure also relates to a system for implementing the process.
Claims19
A process for improving heating values of a cellulosic waste material, the process comprising the steps of:
- treating the cellulosic waste material with an acid solution in a treatment vessel to form treated cellulosic waste material;
- recovering heat produced by the treating of the cellulosic waste material;
- and
- filtering the treated cellulosic waste material in a filtration device to form a filter cake;
- wherein the treated cellulosic waste material comprises an allotrope of carbon.
2 more elements
A system for improving heating values of a cellulosic waste material, the system comprising:
- a treatment vessel for treating the cellulosic waste material with an acid solution, the treatment vessel comprising a heat recovery element;
- a filtration device in fluid communication with the treatment vessel for separating a filter cake from a recovered acid solution;
- and
- an acid recovery component in fluid communication with the filtration device and the treatment vessel for recycling the recovered acid solution from the filtration device to the treatment vessel;
- wherein the acid solution comprises an at least 14 molar solution of a strong acid.
