A high acidity extent, as a result of the activation process bleaching earth, is major drawback in production bleached-palm oil. The earth generates problems for equipment well product, which are economically disadvantageous. Addressing this pivotal issue manufacture, more environmentally friendly and efficient using thermal evaluated. Two types bentonite-bleaching collected from two different ...

The aim of this study was to search vegetable oil bleaching abilities 30 different adsorbent materials placed into four groups (natural clay, acid-activated natural synthetic adsorbent, metal-organic frames). After treatment against control sample, color (L, a*, b* values), weight loss (%), free fatty acidity (FFA), peroxide value (PV), and the specific extinctions K232 K270 were measured. Base...

High free fatty acids in waste cooking oil can interfere with the re-use of oil. Therefore, absorption technique is one way that reduce contained Aim: The purpose this study to find out ability Reactivated Spent Bleaching Earth (RSBE) adsorb be biodiesel products. In study, was collected from fried food sellers Bekasi, while spent bleaching earth (SBE)-one solid wastes produced by refinery palm...

In this laboratory scale study, impregnated almond shell activated carbon was used as adsorbent to investigate its feasibility for nitrate adsorption from aqueous medium. The effects of activated carbon dosage and contact time have been examined in batch experiments. Experimental data show that impregnated activated carbons by Fe0, Fe2 (SO4)3, and FeSO4 were more effective than virgin almond ac...

In the present study, activated bleaching earth was used as clay adsorbent for an investigation of the adsorbability and adsorption kinetics of acid dyes (i.e., acid orange 51, acid blue 9, and acid orange 10) with three different molecular sizes from aqueous solution at 25 degrees C in a batch adsorber. The rate of adsorption has been investigated under the most important process parameters (i...

Vegetable oil is one of the basic food items which is consumed by almost every human being in this universe. Therefore quality of vegetable oil should be good enough so that it accounts for healthy life. In vegetable oil manufacturing there are four major steps involved which are neutralization, degumming, bleaching and deodorization. Among these steps bleaching is the very important and critic...
