Hydrothermal carbonization of waste biomass
Hydrothermal carbonization (in acronym, HTC) is a thermochemical conversion process through which it is possible to directly transform wet organic substrates into a carbonaceous material, referred as hydrochar. Hydrochar has chemical and physical characteristics that make it similar to fossil peats …

Modeling of carbonization and stalling during radiofrequency ablation and electrosurgery
… high-temperature conditions where denaturation, carbonization, and charring occur. Conventional thermal and electrical models assume instantaneous heat propagation and neglect relaxation effects, latent heat absorption, and irreversible biochemical reactions, resulting in limited predictive …

Utilization of aqueous product generated by hydrothermal carbonization of waste biomass
Hydrothermal carbonization (HTC) is a thermochemical treatment process that allows for the conversion of relatively dilute biomass slurries into value added products which are hydrochar and filtrate. This investigation focuses on the potential for utilization of the filtrate (aqueous by-product) …

Application of Hydrothermal Carbonization, Membrane Distillation, and Algae Cultivation for Sustainable Dairy Manure Treatment
… treatment methods that incorporates hydrothermal carbonization (HTC), algae cultivation, and membrane distillation (MD). HTC converts dairy manure into a low-grade coal that can be used as an energy source, while expelling nutrients into the HTC aqueous product (HAP). The algae can be cultivated …

Improvement of kiln design and combustion/carbonization timing to produce charcoal from agricultural waste in Developing countries
… biomass. The process involves the combustion and carbonization of biomass at sustained high temperature in an air-tight metal barrel kiln to produce char. The char produced from Haiti's main agricultural waste product, bagasse, must be powderized, mixed with a binder, compressed into briquettes, …

Factors affecting the yields and properties of the products of the low-temperature carbonization of Penn-Lee coal fromm southwestern Virginia
… study the factors affecting the low-temperature carbonization of seam number one, Penn-Lee coal from southwestern Virginia, by determining the effect of pretreatment of the charge, temperature of the retorting gas, and time of retorting on the yields and properties of the products of …

The chlorination of midlothian coal to produce a liquid adsorbent active carbon
… all of these processes involve a low temperature carbonization of the raw material followed by a slow, controlled oxidation of the carbonized product. A high temperature of carbonization (above 600°C.) results in a product which is not active and cannot be activated. Any selection of a process or …

The effect of preoxidation on the coking properties of Penn-Lee coal
… of treatment that can be used, low-temperature carbonization is one of the most promising. Nearly all of the coke and coal chemicals produced today come from the production of high temperature coke. However, there are many lower rank coals not suited for metallurgical purposes that will produce …
