The present study explores the viability of microwave irradiation for the preparation of activated carbon (OPAC) from oil palm fiber, abundantly available from the oil palm processing industries. The activation process was performed at the microwave power of 360W and irradiation time of 5 min. The BET surface area, pore volume and average pore size of OPAC were 707.79 m(2)/g, 0.3805 m(3)/g and 22.11 angstrom, respectively. The monolayer adsorption capacity of OPAC for methylene blue was 312.5 mg/g. The finding provides a strong evidence to support the potential use of microwave heating as an alternative activation technique. (C) 2010 Elsevier B.V. All rights reserved.

Intermediate Pyrolysis of Desert Date Shell for Conversion to High-Quality Biomaterial Resources

Garba Kabir, Isah Yakub Mohammed, Yousif Abdalla Abakr, Bassim H. Hameed

Summary: This study conducted intermediate pyrolysis on desert date shells for the first time and demonstrated their potential as a biomass feedstock for producing high-quality bio-oil and biochar. Fourier transform infrared spectroscopy (FTIR), elemental analysis, and gas chromatography-mass spectrometry (GC-MS) were used to analyze the composition of the bio-oil. The results showed that the bio-oil had a diverse composition rich in oxygenated compounds such as acids, phenolics, and benzene derivatives. The ultimate analysis revealed a higher carbon content and lower oxygen content in the bio-oil compared to the desert date shell. The findings suggest that desert date shells can be an attractive feedstock for producing valuable biomaterials.

Conversion of a mixture of date palm wastes to mesoporous activated carbon for efficient dye adsorption

Hattan A. Alharbi, Bassim H. Hameed, Khaled D. Alotaibi, Saud S. Al-Oud, Abdullah S. Al-Modaihsh

Summary: In this study, mixture activated carbon (MAC) was developed from a mixture of date palm wastes through hydrothermal carbonization and microwave-assisted H3PO4 activation. MAC showed mesoporous structure and negatively charged surface with various functional groups. The adsorption capacity of MAC for removing RBBR increased with initial concentration and achieved the maximum at pH 3 and 30 degrees C. Langmuir isotherm and pseudo-first-order kinetic models were the best fit for describing the RBBR-MAC adsorption system. The adsorption process was exothermic, increased randomness at the liquid-solid interface, and controlled by physisorption.

Prediction of phosphate adsorption amount, capacity and kinetics via machine learning: A generally physical-based process and proposed strategy of using descriptive text messages to enrich datasets

Baiqin Zhou, Huiping Li, Ziyu Wang, Hui Huang, Yujun Wang, Ruichun Yang, Ranran Huo, Xiaoyan Xu, Ting Zhou, Xiaochen Dong

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
