The present study concerned the production of glucose-based porous carbon materials by a one-step acid-catalyzed HTC. samples were characterized elemental analysis (EA), scanning electron microscope (SEM), Brunauer–Emmett–Teller (BET), Fourier transform infrared (FTIR) and point zero charge (pzc). Experimental results showed that addition sulfuric acid (SA) with different dosages in HTC system ...

In this paper, we investigated the carbonization characteristics of lignin hydrochar prepared by hydrothermal and established a model for predicting degree using near-infrared spectroscopy partial least squares regression. The carbon content hydrothermally carbonized at temperature 200 ℃ was higher approximately 3 wt% than that untreated sample, tended to gradually increase as heating time incr...

Abstract The purpose of the paper is to illustrate basis design a pilot-scale reactor built convert putrescent and high-water content biowaste into stabilized product by using Hydrothermal Carbonization process (HTC). hydrothermal carbonization selected has been previously studied in bench-scale optimize parameters such as temperature, reaction time, water-to-dry matter ratio then scaled up at ...

In this manuscript, a dramatic increase in the energy density of ~ 69 Wh kg⁻¹ and an extraordinary cycleability ~ 2000 cycles of the Li-ion hybrid electrochemical capacitors (Li-HEC) is achieved by employing tailored activated carbon (AC) of ~ 60% mesoporosity derived from coconut shells (CS). The AC is obtained by both physical and chemical hydrothermal carbonization activation process, and co...

Highly uniform samples of carbon nanofoam from hydrothermal sucrose carbonization were studied by helium ion microscopy (HIM), X-ray photoelectron spectroscopy (XPS), and Raman spectroscopy. Foams with different densities were produced by changing the process temperature in the autoclave reactor. This work illustrates how the geometrical structure, electron core levels, and the vibrational sign...

Unusual structure of low-density carbon nanofoam, different from the commonly observed micropearl morphology, was obtained by hydrothermal carbonization (HTC) of a sucrose solution where a specific small amount of naphthalene had been added. Helium-ion microscopy (HIM) was used to obtain images of the foam yielding micron-sized, but non-spherical particles as structural units with a smooth foam...
