Summary: In this study, different valences of metal chlorides were used as co-catalysts in a Type II deep eutectic solvent (DES) system to enhance the pretreatment of oil palm fronds (OPF). The results showed that using ChCl:CaCl2 center dot 6H(2)O/1 wt% CuCl2/30 vol% water and ChCl:CaCl2 center dot 6H(2)O/1 wt% FeCl3/20 vol% water as pretreatment conditions could achieve high xylose recovery from OPF. Additionally, these co-catalysts were effective in removing lignin, xylan, and arabinan from OPF. Therefore, using DES + co-catalyst system with additional water content can be a promising approach for OPF pretreatment in biorefinery processes.

Summary: This study utilized hot compressed water extraction (HCWE) for the extraction of crude palm oil (CPO). The quality of the extracted CPO was analyzed to evaluate possible product degradation. The results showed that the CPO extracted using HCWE had low FFA and low DAG, indicating higher quality. The fatty acid composition of the extracted CPO was similar to commercial CPO, suggesting no undesired reaction occurred during the extraction process. HCWE has the potential to replace screw press systems, but further economic analysis is needed to evaluate its prospects.

Summary: This study investigated the potential of date palm residues as a source of biomethane and bioethanol production in arid regions. Pretreatment with concentrated phosphoric acid resulted in a cellulose-rich solid fraction and a hemicellulose-rich liquor. Two scenarios were followed, with the first scenario producing methane from the pretreated solid and liquor, and the second scenario producing ethanol from the pretreated solid and methane from the liquor. The second scenario was recommended for the biorefining of date palm residues.

Summary: This study reports hydrothermal liquefaction technology carried out on local Malaysian oil palm fronds to produce solid bio-char and liquid bio-oil. Observations showed that bio-oil yield percentage increased and bio-char yield percentage decreased with higher reaction temperature and time, leading to improved combustion properties of bio-char and bio-oil. Major chemical compounds identified in bio-oil by GC-MS were phenolic compounds and their derivatives, alcohols, ketones, and esters.

Summary: In this study, the dealkylation-based visbreaking of heavy oil in a hot compressed water environment was investigated. It was found that the solubilization of water reduces the viscosity of heavy oil, leading to an increase in the reaction rate of dealkylation. The hydration reaction with solubilized water suppresses condensation and extends the reaction time window for dealkylation, resulting in higher yields and lower viscosity of the products.

Summary: Torrefaction of oil palm fronds at 300 degrees Celsius for 40 minutes significantly improves the fuel properties, increasing the net calorific value and fixed carbon content. Pellet fuels derived from torrefied biomass exhibit higher calorific values compared to raw biomass, demonstrating the effectiveness of torrefaction in elevating energy output. An optimal mass proportion of torrefied oil palm fronds and used bleaching clay was identified as 70:30, resulting in the highest calorific value recorded.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
