Abstract: Desulfurisation of 1-dodecanethiol was performed by adsorption process on MgO adsorbent. The adsorbant was characterized by determining the adsorption isotherms, specific surface area, pore volume and average pore diameter. Adsorption experiments were performed in continuous system at 300-450�C, 5 atm and volume hourly space velocities of 1�2 h-1. Conversion of 1-dodecanetol increases with increasing temperature and decreasing volume hourly space velocities. It was identified the stage determinant of the proce… Show more

Metaldehyde is a toxic molluscicide that has the potential to contaminate water supplies and damage aquatic life. Existing water treatment methods are ineffective at removing it from water bodies. In this study, oil palm kernel biochar (OPKB) and rice husk biochar (RHB) were utilized to assess metaldehyde adsorption. Using a batch adsorption approach, the physicochemical parameters of biochar and their metaldehyde adsorption capacities were investigated. The results indicated that the metaldehyde adsorption capacities of both varieties of biochar are significant. Considering the initial concentration of metaldehyde, contact time, and adsorbent dosages, OPKB demonstrated a higher metaldehyde adsorption capacity than RHB. The study examined metaldehyde’s effects on OPKB and RHB using Langmuir and Freundlich isotherms. Both models provided a good fit, with the Freundlich model slightly better fitting. The study also used pseudo-first and second order kinetic models, revealing that the adsorption process follows pseudo-second-order kinetics for both biochar. This information can aid in developing efficient and successful metaldehyde removal technologies from contaminated water sources. This study showed that oil palm biochar has the potential to be an effective adsorbent for removing metaldehyde from contaminated water.

Producing an eco-friendly fuel with the least amount of sulfur compounds has been an ongoing issue for petroleum refineries. In this study, bentonite (which is a cheap material and is locally available in abundance) is employed to prepare a nano-silica catalyst with a high surface area to be used for the oxidative desulfurization of kerosene. Two composite catalysts of Fe/silica were supported on CAT-1 (0% HY-zeolite and 100% nano-silica) and CAT-2 (20% HY-zeolite and 80% nano-silica). The activity of the catalysts was evaluated in a batch ODS (oxidative desulfurization) process at temperatures of 30, 60, 90, and 120 °C, a pressure of 1 atm, and a reaction time of 30, 60, 90, and 120 min using 120 L/h of air as the oxidant. The results revealed that the highest total sulfur removal efficiency was 50% and 87.88% for 100% nano-silica (CAT-1) and 80% nano-silica (CAT-2), respectively. The experimental data were then used to construct and validate an accurate mathematical model of the process. The operational parameters for eliminating more than 99% of sulfur and producing eco-friendly fuel were then achieved by using the model. The testing methods for these characterizing materials included X-ray diffraction (XRD), thermal gravimetric examination (TGA), X-ray fluorescence (XRF), and surface area (BET). The outcomes indicated that the addition of HY-zeolite increased the activity of the catalyst (CAT-2 > CAT-1).
