Torrefaction Process Of Human Bio Waste

We propose a ‘Waste to Carbon’ thermal transformation of sewage sludge (SS) via torrefaction to a valuable product (fuel) with a high content of carbon. One important, technological aspect to develop this concept is the determination of activation energy needed for torrefaction. Thus, this research aimed to evaluate the kinetics of SS torrefaction and determine the effects of process ...

Mar 11, 2016· Torrefaction is thermo-chemical process which can improve solid fuel quality as well as grindability. In previous studies, torrefaction has been studied mainly for removal of moisture and for improving grindability. In this experiment, the characteristics of torrefied waste sawdust were studied especially for its energy yield.

Apr 03, 2019· It uses virtually no fossil fuels in the process, with the exception of some electricity for fans and other ancillary equipment. This is because, during torrefaction, the hemicellulose component of the woody biomass is volatilized, producing combustible gases that produce the thermal energy required for both pre-drying and torrefaction when burned.

Torrefaction of biomass, e.g., wood or grain, is a mild form of pyrolysis at temperatures typically between 200 and 320 °C. Torrefaction changes biomass properties to provide a better fuel quality for combustion and gasification applications. Torrefaction produces a dry product with no biological activity like rotting.
