Binary interaction parameters from reacting mixture data. Supercritical biodiesel process with CO2 as cosolvent
(2019-01-01)
Article
Open AccessA method is presented for the calculation of binary interaction parameters from reacting mixture data. The process studied is the supercritical methanol transesterification of triolein with CO2 as cosolvent. The reaction ... -
Biodiesel production using supercritical methanol/carbon dioxide mixtures in a continuous reactor
(Elsevier Science Ltd., 2011-03-01)
Article
Restricted access - publisher's policyFatty acid methyl esters (biodiesel) were produced by the transesterification of triglycerides with compressed methanol (critical point at 240 C and 81 bar) in the presence of solid acids as heterogeneous catalyst (SAC-13). ... -

Effect of reactor type on trans fatty acid and stearate formation in fat hydrogenation in SCF solvent
(2008-01-02)
Article
Restricted access - publisher's policyHydrogenation of vegetable fats is an important biomolecule modification process, traditionally carried out in a slurry reactor at low pressure (2–6 bar). Here, the hydrogenation of sunflower oil in supercritical propane ... -
Extraction of solid lanoline from raw wool with near-critical ethanol-modified CO2 —A mass transfer model
(2019-03-01)
Article
Open AccessThis study deals with the modeling of the extraction of solid lanoline from raw wool under near-critical conditions using 5% ethanol in CO2, using our previous experimental data. A mass-transfer model is developed to explain ... -
Fatty oil hydrogenation in supercritical solvents: process design and safety issues
(2011-03-02)
Article
Restricted access - publisher's policyA simulation study of a SCF process is carried out using Aspen™ with previously available catalytic kinetics for the simulation of the reactor. Two supported catalysts were considered: a standard Pd/carbon, and an egg-shell ... -
Glycerol desorption from ion exchange and adsorbent resin using supercritical fluid technology: An optimization study
(2011-09)
Article
Restricted access - publisher's policyIn this study, glycerol desorption from Purolite® PD206 resin was investigated using conventional and supercritical fluids (SCF) techniques. Untreated biodiesel was purified by dry washing using the resin and, after ... -
Hybrid nonlinear autoregressive neural network—Weibull statistical model applied to the supercritical extraction of lanolin from raw wool
(Springer, 2020-09-09)
Article
Open AccessSupercritical extraction of lanolin from raw wool with modified CO2 (5% ethanol) at temperatures above the melting point of lanolin (T = 36–42 ºC) is difficult to model because of the multicomponent diffusion in the liquid ... -
Mathematical modelling of supercritical fluid extraction of liquid lanoline from raw wool. Solubility and mass transfer rate parameters
(2020-12-01)
Article
Open AccessA new mathematical model is presented for the supercritical fluid extraction of lanoline from wool using near-critical ethanol-modified CO2, using our previous experimental data. The model is intended to account for the ... -
