Quality variation of pyrolytic products from anaerobic digestion crop waste: Influence of increasing inorganics through anaerobic digestion and different pyrolysis conditions. Journal of Analytical and Applied Pyrolysis, 190, Article 107135. https://doi.org/10.1016/j.jaap.2025.107135

A variety of scenarios concerning the anaerobic digestion (AD) process, due to the amount of material remaining, have been the subject of studies to increase circularity and to generate further high-value products in addition to biogas. Digestate, or...

Determination of pore network accessibility in hierarchical porous solids (2017)
Journal Article
Rigby, S. P., Hasan, M., Stevens, L., Williams, H. E., & Fletcher, R. S. (2017). Determination of pore network accessibility in hierarchical porous solids. Industrial & Engineering Chemistry Research, 56(50), 14822-14831. https://doi.org/10.1021/acs.iecr.7b04659

This paper validates the hypothesis that the supposedly non-specific adsorbates nitrogen and argon wet heavy metals differently, and shows how this unexpected effect can be actively utilised to deliver information on pore inter-connectivity. To explo... Read More about Determination of pore network accessibility in hierarchical porous solids.
