Treatment of urban sludge by hydrothermal carbonization
Bioresource Technology, 2017Urban sludge was treated by Hydrothermal carbonization (HTC). The effect of hydrothermal carbonization temperature, mixing with or without catalysts on solid products yield, heavy metal contents, turbidity and COD value was evaluated. The result showed solid products yield decreased from 92.04% to 52.65% when the temperature increased from 180 to 300°C.

Hydrothermal carbonization and torrefaction of grape pomace: A comparative evaluation
Bioresource Technology, 2014 Grape pomace was treated by hydrothermal carbonization (sub-critical water, 175-275 degrees C) and torrefaction (nitrogen atmosphere, 250 and 300 degrees C), with mass yield of solid product (char) ranging between 47% and 78%, and energy densification ...

Hydrothermal carbonization of agricultural residues
Bioresource Technology, 2013The work presented in this article addresses the application of hydrothermal carbonization (HTC) to produce a solid fuel named HTC-Biochar, whose characteristics are comparable to brown coal. Several batch HTC experiments were performed using agricultural residues (AR) as substrates, commonly treated in farm-based biogas plants in Germany. Different AR

Hydrothermal carbonization of lignocellulosic biomass
Bioresource Technology, 2012Hydrothermal carbonization (HTC) is a novel thermochemical conversion process to convert lignocellulosic biomass into value-added products. HTC processes were studied using two different biomass feedstocks: corn stalk and Tamarix ramosissima. The treatment brought an increase of the higher heating values up to 29.2 and 28.4 MJ/kg for corn stalk and T ...

Hydrothermal carbonization of peat
Solid Fuel Chemistry, 2017The influence of peat hydrothermal carbonization at 180 and 220°C for 8–10 h on the thermal characteristics of the resulting biochar was studied. It was found that hydrothermal carbonization reduced the yield of volatiles to about 50% and increased the calorific value (to 7200 or 7600 kcal/kg for the lower or higher calorific value, respectively); that

Hydrothermal carbonization of microalgae
Biomass and Bioenergy, 2010Abstract Hydrothermal carbonization is a process in which biomass is heated in water under pressure to create a char product. With higher plants, the chemistry of the process derives primarily from lignin, cellulose and hemicellulose components. In contrast, green and blue-green microalgae are not lignocellulosic in composition, and the chemistry is ...
