Catalytic Hydrotreatment of Biomass-Derived Fast Pyrolysis Liquids Using Ni and Cu-Based PRICAT Catalysts

Biomass-derived fast pyrolysis liquids (PLs) are not directly applicable as transportation fuels due to their high oxygen content and limited storage stability. Catalytic hydrotreatment is an efficient technology convert such PLs finished or intermediates that can be used a co-feed for existing oil refinery units. In this paper, we report catalyst screening studies the mild of using commercially available Ni Cu-based PRICAT catalysts at rather conditions (200 °C, initial 140 bar H2 pressure) in batch setup 4 h. Among all catalysts, NI 62/15 showed best performance catalytic terms product properties (highest H/C ratio lowest TG residue). The were also tested deep more severe (350 100 pressure). Here, better than benchmark Picula Ni-Mo when considering yield ratio. Advantageously, hydrogen consumption during reduced, rationalized by lower methanation activity.
