Abstract

Waste oily sludge (OS) was transformed into energy-rich carbonaceous material by a thermochemical conversion process using a microwave-induced process. The aims of this research were to ride the environment of side effect products waste oily sludge, solid fuel production via microwave process of oily sludge. OS samples were collected from North Refineries Company (NRC) Baiji. The microwave process was employed using different ranges of micro-power at different residence time to produce chars under nitrogen atmosphere and the process showed that solid production increased gradually as power increased. Raw and char products materials were characterized using proximate, CHNS-O and HHV analyses and the results exhibited that the chars have high energy values with 18.35 MJ/kg as the maximum calorific value. It was concluded that the collected oily sludge waste was rich in carbon and high-value petroleum materials and the char yield has a higher-heating value which is expected to be used as solid carbon fuel.

Abstract

Manganese dioxide was laden hooked on biochar sourced from chicken feather to obtain a biochar-supported manganese dioxide (BSM) composite. In order to reduce the costs of acquisition and minimise the disposal of adsorbents, prepared BSM composite were employed in the sequestration of Levofloxacin (LEVO) from aqueous environment. The physico-chemical features and the adsorption mechanisms of prepared BSM, prior and after the adsorption of LEVO molecules were revealed by Scanning Electron Microscopy and Fourier Transform Infrared spectroscopy techniques. The influence of adsorption parameters including BSM dose, initial concentration, temperature and residence time were studied. The removal of LEVO was significantly influenced by all parameters. Equilibrium data has its fitness in the following order: Redlich-Peterson > Langmuir > Freundlich models. The maximum adsorption capacity of BSM for LEVO was 104.13 mg/g. The kinetic analysis indicates best fittings for pseudo-second- order model suggesting chemisorption as controlled mechanism. Besides, liquid film and intra-particle diffusion had a vital influence on the LEVO sequestration process. Exothermic and spontaneous nature of LEVO uptake by BSM was revealed by thermodynamic analysis. The findings suggested that prepared BSM show high sorption capacity, and recyclability potential towards separation of LEVO from contaminated pharmaceutical wastewater. [ABSTRACT FROM AUTHOR]
