PhD-thesis: Atmospheric carbon removal via industrial biochar systems – a techno-economic-environmental assessment

Fawzy, Samer; Queen’s University Belfast

An in-depth investigation of climate change mitigation strategies was carried out, detailing 3 major approaches, namely emissions reduction, atmospheric carbon removal and radiative forcing geoengineering. Based on an assessment of the prominent carbon removal technologies, it was determined that carbon removal via industrial biochar systems is a very promising approach. Accordingly, the dimensions related to biochar-based carbon removal systems were explored in detail.

Kamini et al. (2023): Biochar in cementitious material – A review on physical, chemical, mechanical, and durability properties

Pravina Kamini G., Kong Fah Tee, Jolius Gimbun, Siew Choo Chin IN: AIMS Materials Science 10, 3,  doi: 10.3934/matersci.2023022

The objective of this paper is to review the potential of biochar as a cementitious material by evaluating its physical, chemical, mechanical, and durability properties. Using biochar as a cementitious material makes it possible to conclude that cement production will be reduced over time by partial replacement, which will also promote and encourage sustainable development in the future.

Zakaria et al. (2023): Production of biochar and activated carbon from oil palm biomass: Current status, prospects, and challenges

Mohd Rafein Zakaria, Mohammad Abdillah Ahmad Farid, Yoshito Andou, Irmawati Ramli, Mohd Ali Hassan IN: Industrial Crops and Products 199, 116767, https://doi.org/10.1016/j.indcrop.2023.116767

Given the lack of a precise technical definition for carbon materials and methods available, studies of biochar and activated carbon (AC) are progressively colliding with one another. Therefore, based on their respective backgrounds and methods of synthesis, their differences are outlined in this report. The present review highlights recent progress and development of biochar and AC from oil palm biomass by looking at the technical aspects of product generation and potential applications.

Li et al. (2023): An efficient biochar adsorbent for CO2 capture: Combined experimental and theoretical study on the promotion mechanism of N-doping

Hongxian Li, Minghui Tang, Xinlei Huang, Ling Wang, Qi Liu, Shengyong Lu IN: Chemical Engineering Journal 466, 143095, https://doi.org/10.1016/j.cej.2023.143095

Although many N-doped carbon materials have been prepared for CO2 adsorption in recent years, the promotion mechanism has not been clearly proposed. In this study, a series of N-doped biochars were successfully prepared by a facile solvent-free method. Among them, the biochar prepared with corncob powder, K2CO3 and urea at 800 °C showed the highest adsorption capacity (5.69 mmol/g at 0 °C and 1 bar) and selectivity (38.24 at CO2/N2 = 10/90).

Lim et al. (2023): Unique CO2 adsorption of pine needle biochar-based activated carbons by induction of functionality transition

Chaehun Lim, Seo Gyeong Jeong, Seongmin Ha, Naeun Ha, Seongjae Myeong, Young-Seak Lee IN: Journal of Industrial and Engineering Chemistry, https://doi.org/10.1016/j.jiec.2023.04.008

In this work, the authors induced functionality transition of heteroatom-rich pine needle biochar based activated carbon for CO2 adsorption by modulating activation conditions. The surface functionalities and porosity of the activated carbon derived from pine needles were investigated intensively according to the activation conditions. The transition of surface functional groups and development of porosity were observed as activation progressed.

Petersen et al. (2023): Carbon stability and morphotype composition of biochars from feedstocks in the Mekong Delta, Vietnam

H.I. Petersen, L. Lassen, A. Rudra, L.X. Nguyen, P.T.M. Do, H. Sanei IN: International Journal of Coal Geology 271, 104233, https://doi.org/10.1016/j.coal.2023.104233

This study investigates carbon stability of biochars produced from wood, herbaceous, and fruit agricultural waste products from southern Vietnam. Organic geochemistry and petrology have well-established measurable parameters that define degree of preservation of organic carbon in the Earth’s crust. These parameters are utilized, comparatively, to infer the organic carbon stability in biochars relative to that preserved in the geological carbonaceous rocks.
