Hydrothermal carbonization (HTC) of sewage sludge reduces the waste volume and can be source of energy and valuable products. Furthermore, HTC offers several advantages over conventional drythermal pretreatments, as no prior drying is requested, and the high quality of the char produced promotes applications as energy production and storage, wastewater remediation, and soil amendment.

Carbonization, more narrowly defined, refers to conversion of a starting material into carbon, or a carbonrich solid. It is entirely possible, and indeed often done, to pyrolyze a hydrocarbon feedstock for the purpose of carbonization, but carbonization is not simply pyrolysis by another name.

Hydrothermal carbonization (HTC) is a significant process, first used to generate coal from cellulose way back in 1913 (Libra et al., 2011). HTC converts food waste to energyrich resources under wet conditions and at relatively low temperature (180°C350°C). During HTC, a series of reactions including hydrolysis, condensation, dehydration ...

Carbonization is the art of reinventing the waste biomass into a carbon−/energyrich charcoal. It redefines the principles of renewable energy and power generation. Char is produced by a pyrolysis process in which the biomass is heated in an inert atmosphere to high temperatures until absorbed volatiles are expelled thus enriching its heating value and energy content.

The stabilization process is a highly exothermic reaction that begins at ∼ 200230°C and peaks at 300320°C. The stabilization is achieved by allowing the fiber to form a ladder type structure in the early stages of the carbonization process.

Coal is a black or brownishblack sedimentary rock that can be burned for fuel and used to generate is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the United States.
