The essential objective of this work was to co‐pyrolyze a binary mixture of date and cherry seeds in a fixed‐bed reactor. The experimental variables influencing the output of products, such as the pyrolysis temperature, pyrolysis duration, particle size, and heating rate, were optimized. The maximum liquid fraction yield (55.55 % with a bio‐oil yield of 29.70 %) was attained at 500 °C for 60 min at a heating rate of 40 °C min−1 and a particle size of 0.25 mm. The Fourier transform infrared and gas chromatography‐mass spectrometry results revealed that the bio‐oil was predominantly composed of oxygenated hydrocarbons, primarily higher acids (52.05 %), esters (23.67 %), and phenols (13 %). Biochar was converted into activated carbon, which possessed a Brunaer‐Emmett‐Teller surface area of 1055.55 m2g−1. The amorphous structure of this carbon was confirmed by field emission‐scanning electron microscopy and X‐ray diffraction measurements.

“…The C% and H% of BO were 81.23 % and 10.55 %, respectively. A high content of C% and H% in a fuel results in a higher calorific value [15,21]. Also, the lower O% in fuel increases its stability.…”

“…The selection of K 2 CO 3 as an activating agent instead of KOH has attracted much interests owing to its less corrosive and nonhazardous nature (according to the OSHA Hazard Communication Standard), higher catalytic activity, water solubility, recyclability, lower cost, and serving as a salt template for micropore development. − Meanwhile, K 2 CO 3 is suitable for both impregnation and solid-mixing methods to be introduced into carbon precursors.

The current work systematically studied the technical feasibility of potassium-looping activation of biochar using K 2 CO 3 for the coproduction of highly microporous carbon and syngas. Compared with the solid mixing method, the impregnation method showed a higher biochar activation efficiency and produced a higher quality of activated carbon. By the impregnation method, a high yield of activated carbon (60 wt %, per biochar mass) was achieved under the optimal conditions, such as an activation temperature of 800 °C, a mass ratio of biochar to K 2 CO 3 (1:1), and a retention time of 3 h. The activated carbon with a high specific surface area (1091 m 2 /g) and a high microporosity (98%) was obtained. Besides, during the biochar activation process, syngas (CO/H 2 molar ratio of 1.0−1.5 and yield of ∼23 wt %) was generated. The yield and surface area of activated carbon were not obviously reduced after water leaching within three cycles. The potassium-looping system was evaluated to recover and reuse biochar activation agent within subsequent cycles.

As it is now established that global warming and climate change are a reality, international investments are pouring in and rightfully so for climate change mitigation. Carbon capture and separation (CCS) is therefore gaining paramount importance as it is considered one of the powerful solutions for global warming. Sorption on porous materials is a promising alternative to traditional carbon dioxide (CO2) capture technologies. Owing to their sustainable availability, economic viability, and important recyclability, natural products‐derived porous carbons have emerged as favorable and competitive materials for CO2 sorption. Furthermore, the fabrication of high‐quality value‐added functional porous carbon‐based materials using renewable precursors and waste materials is an environmentally friendly approach. This review provides crucial insights and analyses to enhance the understanding of the application of porous carbons in CO2 capture. Various methods for the synthesis of porous carbon, their structural characterization, and parameters that influence their sorption properties are discussed. The review also delves into the utilization of molecular dynamics (MD), Monte Carlo (MC), density functional theory (DFT), and machine learning techniques for simulating adsorption and validating experimental results. Lastly, the review provides future outlook and research directions for progressing the use of natural products‐derived porous carbons for CO2 capture.
