Preparation and Characterization of Biodiesel Produced from Recycled Canola Oil
The purpose of this paper is to evaluate the feasibility of using recycled canola oil as raw material to produce ASTM standard biodiesel. Two-step reaction, acid-catalyzed esterification followed by alkali-catalyzed transesterification, was performed. The high level of free fatty acids ( FFA) in the recycled canola oil was reduced to less than 1% by acidcatalyzed esterification with 40/1 molar ...
متن کاملRecycled palm oil is better than soy oil in maintaining bone properties in a menopausal syndrome model of ovariectomized rat.
Palm oil is shown to have antioxidant, anticancer and cholesterol lowering effects. It is resistant to oxidation when heated compared to other frying oils such as soy oil. When a frying oil is heated repeatedly, it forms toxic degradation products, such as aldehydes which when consumed, may be absorbed into the systemic circulation. We have studied the effects of taking soy or palm oil that wer...
متن کاملCarbon/Attapulgite Composites as Recycled Palm Oil-Decoloring and Dye Adsorbents
Activated clay minerals have been widely used in the edible oil refining industry for decolorization of crude oil by adsorption, and so far many methods have been used to improve their decolorization efficiency. Herein, we successfully prepared a series of carbon/attapulgite (C/APT) composite adsorbents by a one-step in-situ carbonization process with natural starch (St) as the carbon source. I...
متن کاملDwarfs Recycled Galaxies ?
Although cluster dwarf galaxies are often neglected due to their faintness, recent observations demonstrate that they are critical for understanding the physical processes behind galaxy and cluster formation. Dwarfs are the most common galaxy type and are particularly abundant in clusters. Recent observational results suggest that dwarfs in dense environments do not all form early in the univer...
متن کاملA3782 Using recycled wallboard
Much of this material is not reusable and is usually deposited in a landfill. A study conducted in Wisconsin estimated that construction of a typical single family home in 1992 encumbered waste disposal expenses of over $700.2 The study estimated that between 77,000 and 102,000 cubic yards of construction waste was generated in Dane County alone, at a disposal cost of between $1,000,000 and $1,...
