Riva, Lorenzo; Surup, Gerrit Ralf; Buø, Therese Videm; Nielsen, Henrik Kofoed (Journal article; Peer reviewed, 2019) -
Analysis of optimal temperature, pressure and binder quantity for the production of biocarbon pellet to be used as a substitute for coke
Riva, Lorenzo; Nielsen, Henrik Kofoed; Skreiberg, Øyvind; Wang, Liang; Bartocci, Pietro; Barbanera, Marco; Bidini, Gianni; Fantozzi, Francesco (Journal article; Peer reviewed, 2019)In order to contribute to the decarbonization of the economy, efficient alternatives to coal and coke should be found not only in the power sector but also in the industrial sectors (like steel, silicon and manganese ... -
Considerations on factors affecting biocarbon densification behavior based on a multiparameter model
Riva, Lorenzo; Wang, Liang; Ravenni, Giulia; Bartocci, Pietro; Videm Buø, Therese; Skreiberg, Øyvind; Fantozzi, Francesco; Nielsen, Henrik Kofoed (Journal article; Peer reviewed, 2021)The optimization of upscaled biochar pelleting is limited by lack of knowledge regarding the effects of process parameters. A multiparameter model, coupled to a single pellet press unit, was for the first time applied to ... -
Effect of torrefaction on properties of pellets produced from woody biomass
Wang, Liang; Riva, Lorenzo; Skreiberg, Øyvind; Khalil, Roger Antoine; Bartocci, Pietro; Yang, Qing; Yang, Haiping; Wang, Xuebin; Chen, Dengyu; Rudolfsson, Magnus; Nielsen, Henrik Kofoed (Peer reviewed; Journal article, 2020)Torrefaction has been recognized as a promising strategy to improve handling and storage properties of wood-based pellets, thus producing a uniform-quality commodity with high energy density and hydrophobicity. In this ... -
On the self-heating behavior of upgraded biochar pellets blended with pyrolysis oil: Effects of process parameters
Riva, Lorenzo; Cardarelli, Alessandro; Andersen, Geir Johan; Buø, Therese Videm; Barbanera, Marco; Bartocci, Pietro; Fantozzi, Francesco; Nielsen, Henrik Kofoed (Peer reviewed; Journal article, 2020) -
Production and application of sustainable metallurgical biochar pellets
Riva, Lorenzo (Doctoral Dissertations at the University of Agder; no. 284, Doctoral thesis, 2020)The effective decarbonization of our society must be boosted through the promotion of efficient alternatives to fossil fuels. This transition should take place gradually, involving a broad range of actors and technologies. ...
