Problem statement: We have recently introduced several important improvements in the measurement of distillation curves for complex fluids. The modifications include a compositionexplicit data channel for each distillate fraction and temperature measurements that are true thermodynamic state points that can be modeled with an equation of state. The composition-explicit information is achieved w...

BACKGROUND AND OBJECTIVES: From August to October 2019, several provinces in Sumatra and Kalimantan had faced severe forest fires, causing thousands of citizens to suffer respiratory disorders. This study aims to assess waste handling in palm oil plantation manage by smallholders and the correlation palm oil plantation waste handling with the fireland in Sumatera, especially on...

Olive waste cake (OWC) is underestimated as an agricultural waste. In this work, OWC extract were obtained by ethanol. Antioxidant efficacy of ethanolic OWC extract at levels of 100, 200, 400 and 600 ppm were studied. Samples of sunflower oil mixed with OWC extract were intermittent heated at 180±5°C for 4 hr / day, for 5 consecutive days and has been assayed for stabilization of sunflower oil ...

Waste oil is an inexpensive source for biodiesel production, but the high amount of impurities present (free fatty acids, oxidation products) impedes its practical application. The aim of this work is to assess the purification efficiency of the adsorption process with eggshell and its active carbon. Carbonization of eggshell was done at 200 ºC for 4 hours. For activation of the resultant carbo...

Biodiesel waste is a by-product of the biodiesel production process that contains a large amount of crude glycerol. To reuse the crude glycerol, a novel bioconversion process using Enterococcus faecalis was developed through physiological studies. The E. faecalis strain W11 could use biodiesel waste as a carbon source, although cell growth was significantly inhibited by the oil component in the...

it is known that native oil-degrading microorganisms are ubiquitous. they can be isolated from contaminated soils. in this study, biodegradation experiments were carried out to evaluate the efficiency of pollutant removal by adding the selected microorganisms. five mixed cultures and 3 single bacteria strains, pseudomonas sp., arthrobacter sp. and mycobacterium sp. were isolated from hydrocarbo...
