Conventional steam activation for conversion of oil palm kernel shell biomass into activated carbon via biochar product
Conventional steam activation pyrolysis of waste materials such as oil palm kernel shell for production of biochar was investigated using central composite design. Conventional steam activation was carried out via an initial carbonization of oil palm kernel shell to obtain biochar and thereafter steam activation of the biochar using the conventional heating to produce activated carbon. Addition...
متن کاملIn Vitro Antioxidative Evaluation of α- and β-Carotene, Isolated from Crude Palm Oil
The present work describes the isolation of α - and β -carotene from crude palm oil and their antioxidant potential in an in vitro model. Pure product was isolated by the method adopted. Antioxidant activities of the isolated α - and β -carotene were analyzed in five different concentrations of 0.001, 0.005, 0.01, 0.05, and 0.1% (w/v). From the several assays conducted, an observation was made ...
متن کاملSupercritical Fluid Extraction of β-Carotene from Crude Palm Oil Using CO2 in a Bubbler Extractor: Mass Transfer Study
In this study, the diffusivity and volumetric mass transfer coefficients for the extraction of β-carotene from crude palm oil using CO2 solvent in supercritical fluid were determined in the pressure range of 7.5-17.5 MPa and temperature range of 80-120 ºC. For this purpose, a statistical method was applied in order to minimize the number of experiments required. The volumetric ma...
متن کاملPreparation of vesicle drug carrier from palm oil- and palm kernel oil-based glycosides.
A new mixture of alkyl glycosides derived from palm oil (PO) or palm kernel oil (PKO) was synthesised. This mixture contains glycosylated disaccharide of either maltose or lactose with aliphatic chain that varies according to the PO or PKO fatty acids composition. The synthesis method produced no polymerised sugar unlike the production of the commercial glycosides (APG). The mixture only contai...
متن کاملAdsorption of aqueous Cd(II) and Pb(II) on activated carbon nanopores prepared by chemical activation of doum palm shell
Non-uniformly sized activated carbons were derived from doum palm shell, a new precursor, by carbonization in air and activation using KOH, NaOH and ZnCl2. The activated carbon fibres were characterised by X-ray diffraction, N2 adsorption-desorption, scanning electron microscopy, particle size analysis and evaluated for Cd(II) and Pb(II) removal. The 40-50 nm size, less graphitic, mesoporous Na...
