Surface area development of sewage sludge during pyrolysis
TLDR
In this paper, surface area and pore structure characterization of the resultant char was evaluated using an accelerated surface and porosimetry system (ASAP 2000), and the effects of process parameters, temperature and hold time were found to be significant.About:

Characterization of gas shale pore systems by porosimetry, pycnometry, surface area, and field emission scanning electron microscopy/transmission electron microscopy image analyses: Examples from the Barnett, Woodford, Haynesville, Marcellus, and Doig units
TL;DR: In this article, the nanometer-scaled pore systems of gas shale reservoirs were investigated from the Barnett, Marcellus, Woodford, and Haynesville gas shales in the United States and the Doig Formation of northeastern British Columbia, Canada.

Kathrin Weber,Peter Quicker +1 more
TL;DR: In this article, a large number of experiments on biochar production is presented to give a general overview of the properties that can be achieved by feedstock selection and process design, including torrefaction as well as slow pyrolysis at high temperatures.

Influence of pyrolysis temperature on characteristics and heavy metal adsorptive performance of biochar derived from municipal sewage sludge.
TL;DR: In the batch experiments of cadmium(II) adsorption, the removal capacity of biochars improved under higher temperature, especially at 800°C and 900°C even one order of magnitude higher than that of the commercial activated carbon.

Physical Adsorption on Non‐Uniform Surfaces
TL;DR: In this article, a quasi-chemical theory of interaction (BET) was used to analyze adsorption on a uniform surface and showed that the hypotheses of the BET theory lead to substantially no adorption beyond the first layer if E2 = EL, and stepwise isotherms if E1>E2>E3>···>EL.

Behavior of chromium, nickel, copper, zinc, cadmium, mercury, and lead during the pyrolysis of sewage sludge.
TL;DR: For sewage sludge, which contains metals with similar chemical and physical properties such as Cr, Ni, Cu, Zn, Cd, and Pb, pyrolysis at 500-600/sup 0/C might prove suitable since no metals are released to the atmosphere and a char is produced that is well suited for disposal in an inorganic sanitary landfill.
