Cutz, L. (author), Maldonado de León, H.A. (author), Zambrano, Gamaliel (author), Al-Naji, Majd (author), de Jong, W. (author)The oil palm industry has been under public scrutiny during the last decades due to environmental and social issues related to its practices. Oil palm (Elaeis guineensis Jacq.) trunks (OPTs) are of special interest as they are left idle in the field after the replanting process which is performed every 25 years. This common practice results...journal article 2023

Zhang, Y. (author), Liu, X. (author), Ren, S. (author), Jing, R. (author), Lin, P. (author), Apostolidis, P. (author), Erkens, S. (author), Wang, Xuancang (author), Scarpas, Athanasios (author)Lignin, one of the most abundant natural polymers, has been extensively studied as an additive in bituminous binders. Even though the lignin improves the overall resistance against oxidative aging of bitumen, it could lead to high thermal cracking sensitivity. In this study, a bio-oil (i.e., rapeseed oil) is implemented in lignin-modified...journal article 2022

Yáñez, Édgar (author), Meerman, Hans (author), Ramirez, Andrea (author), Castillo, Édgar (author), Faaij, Andre (author)The oil industry needs to reduce CO<sub>2</sub> emissions across the entire lifecycle of fossil fuels to meet environmental regulations and societal requirements and to sustain its business. With this goal in mind, this study aims to evaluate the CO<sub>2</sub> mitigation potential of several bio-oil co-processing pathways in an oil refinery....journal article 2020

Sun, Z. (author), Yi, Junyan (author), Chen, Zining (author), Xie, Sainan (author), Xu, Meng (author), Feng, Decheng (author)The chemical and rheological properties of polymer modified bitumen incorporating bio-oil derived from waste cooking oil (WCO) were investigated in this paper. At first, the chemical composition and mixing mechanism of the experimental materials were analysed from the perspective of functional group, and the influence of bio-oil on the...journal article 2019

Sun, Z. (author), Yi, Junyan (author), Feng, Decheng (author), Kasbergen, C. (author), Scarpas, Athanasios (author), Zhu, Yiming (author)Bio-oil produced during the production of biodiesel is a burden to the environment. Recycling and utilization of bio-oil as a substitute for pavement bitumen can help to build an environmentally-friendly and clean infrastructure. In this study, the bio-bitumen was prepared by bio-oil based on free radical polymerization. Different kinds of...journal article 2018

Remiro, Aingeru (author), Arandia, Aitor (author), Oar-Arteta Gonzalez, L. (author), Bilbao, Javier (author), Gayubo, Ana G. (author)The regenerability of Ni catalysts in reforming reactions is a key factor for process viability. Accordingly, this study addresses the regeneration of two spinel NiAl<sub>2</sub>O<sub>4</sub> type catalysts by reaction-regeneration cycles in the oxidative steam reforming (OSR) of raw bio-oil. The spinel type catalysts were prepared by...journal article 2018

Tzanetis, Konstantinos F. (author), Posada Duque, J.A. (author), Ramirez, Andrea (author)This paper shows a detailed analysis of a biomass HTL process by considering changes in three main reaction variables (i.e. catalysts (water, Na<sub>2</sub>CO<sub>3</sub>(aq.), and Fe(aq.)), temperature (280–340 °C), and catalysts/biomass mass ratio (0–0.33 kg catalysts/kg biomass)), and by assessing their influence on the techno-economic and...journal article 2017

Arandia, Aitor (author), Remiro, Aingeru (author), Oar-Arteta Gonzalez, L. (author), Bilbao, Javier (author), Gayubo, Ana G. (author)A reaction scheme has been proposed for the oxidative steam reforming (OSR) of raw bio-oil on a Rh/CeO<sub>2</sub>-ZrO<sub>2</sub> catalyst, based on the study of the effect reaction conditions (temperature, space time, oxygen/carbon ratio and steam/carbon ratio) have on product yields (H<sub>2</sub>, CO, CO<sub>2</sub>, CH<sub>4</sub>,...journal article 2017
