“…Domínguez et al [41] studied the pyrolysis of sewage sludge and reported that a high concentration of metals, especially for iron, would favor reactions between the metals and organic compounds, promoting tar cracking to generate more gaseous products. An enhanced hydrogen production was observed with the presence of Iron/Nickel-loaded catalysts [42] or nickel-coated distributor of the gasifier [43]. Therefore, it suggests that the Fig.…”

Steam Alkali catalyst Hydrogen Hydrothermal carbonization a b s t r a c tHydrothermal carbonization is an effective pretreatment for further thermal conversion of high moisture biomass without a high cost of a dehydration process. The current paper concerns the properties of hydrochar derived from hydrothermal carbonization of sewage sludge, and the feasibility of steam gasification of hydrochar for hydrogen-rich gas production was investigated. Sewage sludge derived hydrochar was characterized using scanning electron microscopy, Fourier transform infrared spectroscopy, and inductively coupled plasma atomic emission spectroscopy to evaluate its feasibility for gasification application. The effect of reaction temperature, steam to biomass mass ratio, and addition of alkali catalysts on steam gasification characteristics of raw sewage sludge and corresponding hydrochar were evaluated, in terms of major composition of the produced gas, gas yield, gasification efficiency and energy density. The results showed that sewage sludge derived hydrochar was rich in hydrophilic functional groups and increased Fe, Ni, alkali and alkaline earth metals (i.e. K, Na, Ca, Mg), resulting in a higher hydrogen yield and energy efficiency than direct steam gasification of sewage sludge under identical conditions. In addition, hydrogen-rich gas production was also favored with the presence of alkali catalysts, especially for the hydrochar. The present study demonstrates that hydrothermal carbonization provides an effective pretreatment of sewage sludge for production of hydrogen-rich gas via steam gasification.

“…Elemental analyses were carried out on the used catalysts in order to quantify these carbon deposits. The amount of coke deposited on the catalysts during two hours of reaction, expressed as mg C/ g catalyst g organics reacted [37], has been calculated and statistically compared. This comparison shows that the carbon content deposited on the catalyst was higher for the two aqueous fractions obtained from the bio-oils whose pyrolysis took place in the fluidised bed (15528 and 1488 mg C/g catalyst g organics reacted for the pine and the poplar, respectively) than for those whose pyrolysis was carried out in the spouted bed reactor (9612 and 955 mg C/g catalyst g organics reacted for the pine and the poplar, respectively).…”
