In this study, the degradation and mineralization of petrochemical wastewater containing phenol and nitrophenol with chemical oxygen demand (COD) at 260 mg/L and total organic carbon (TOC) at 100 mg/L, were investigated by Sono–photo-Fenton process. The full factorial design of experiment was used to explore the influence of operational variables such as pH, initial concentration of hydrogen […]
Biomass-derived adsorbents have been intensively studied due to their competence in reducing pollutants with conventional methods. Flowers are used as source in medicine, cosmetics and even as adsorbents for pollutant abatement. In this study, the microparticles from Chrysanthemum indicum were used as adsorbent for reducing the Congo red dye concentration from synthetic solution. Batch trials […]
Laboratory experiments conducted for long time on stream (TOS: 14,350 h) provide information on Fischer–Tropsch synthesis (FTS) that is representative of time scales of industrial operations. Operation conditions that deliver desirable conversion and product distribution were investigated. Low gas hourly space velocity (GHSV) gave the highest conversion of 20.97% with the highest C5+ selectivity achieved was […]
In this paper, the effect of chemical treatments on date palm fibers (DPFs) properties was studied; DPFs were first treated with a 5 wt% NaOH aqueous solution for 1 h and then modified using two types of silane coupling agents (3-Mercaptopropyltrimethoxysilane and 3-Aminopropyltrimethoxysilane) with various concentrations (0.1, 0.5, 1 and 2 wt%) to improve the interfacial properties of […]
The literature relatively lacks results and data related to the direct influence of physical aging on the properties of polypropylene and natural rubber blend; so, the objective of this research was to study the influence of thermal and ultraviolet (UV) aging on a natural rubber (NR) SMR-ω and polypropylene (PP) blend. This toughened blend is […]
Industrial steady-flow chemical processes are generally organised as a sequence of individually optimised operations. However, this may not achieve overall optimization since material (as recycle), heat and work transfers overall may not be well balanced. We introduce the idea of a preliminary overall thermodynamic balance to produce a reversible process, with the objective of minimising, […]
The present work reports the application of polyethylene glycol (PEG) cross-linked chitosan (Cht-PEG) as a green corrosion inhibitor. This is the first study reporting the application of Cht-PEG as corrosion inhibitor for mild steel in 1 M sulphamic acid solution. The results of gravimetric measurements, electrochemical study and surface analysis (SEM) are presented in this […]
In the quest for eco-friendly and cost-effective adsorbents for the removal of phenol from aqueous systems, garlic peel has been identified as a potential candidate in our earlier study. In the current investigations, we have studied the performance of garlic peel powder in packed fixed-bed column, to assess its potential for real-time deployment for remediation […]
