Doi: 10.1016/j.fuel.2018.06.078.

Abstract:
A series of Al2O3-TiO2-supported trimetallic CoMoW catalysts were prepared with the aim to study the effect of Mo substitution by W on the catalyst performance in deep hydrodesulfurization (HDS) reaction. The [leer más]

Steam reforming of tar model compounds over Ni/Mayenite catalysts: effect of Ce addition

Authors: Savuto, E; Navarro, RM; Mota, N; Di Carlo, A; Bocci, E; Carlini, M; Fierro, JLG

Fuel. vol: 224. page: 0016-2361.
Date: jul-15. 2018.
Doi: 10.1016/j.fuel.2018.03.081.

Abstract:
Ni-based catalysts are very effective and largely used for the steam reforming of heavy hydrocarbons (tars) generated from biomass gasification, even if Ni suffers from deactivation issues mainly due to carbon deposition, sintering and [leer más]
