چکیده

Many contaminants, such as phosphatides, mucins, free fatty acids, dyes, and compounds that impact the color odor, are present in crude fats oils variable concentrations. The standard chemical refining process removes these contaminants at numerous stages, including activation, carbonization, filtration, absorption, degumming, neutralization, bleaching. While degumming is done to remove phosphatides so hydratable can be precipitated by adding water oil, non-hydrated must eliminated activation open up pore structure of activated carbon. Additionally, acids through neutralization with alkali hydroxides, producing soaps eliminated, undesirable colored impurities bleaching an adsorptive reagent. Subsequently, unwanted adsorbed along adsorbent filtration. Then, get rid unwelcome volatile odiferous elements because antioxidants. equilibrium concentration, values for Ce/qc, b, slopes soybean oil goya olive were calculated using Langmuir isotherm equation. Ce/Qc = 1.Ce/Qo + 1/bQo, Ce Qc percent 1/Qo slope, Qo adsorption capacity, b constant. results % absorption obtained soyabean follows; 86.90, 85.90, 79.70, 78.40 29.60 while 86.10, 84.10, 82.90, 81.80, 77.70, 77.50 respectively. Based on their near range capacities, it was concluded coal successful both oil. However, had a little higher capacity than soya bean

The Effect of Different Concentrations of Activated Carbon with Bleaching Earth During Bleaching Process on Physicochemical Properties of Soybean Oil

Considering the importance of bleaching earth with activated carbon in reduction of impurities in vegetable oils, this study was conducted to investigate the effects of bleaching process on physicochemical properties of the bleached soybean oil. The bleaching process was carried out with bleaching earth (1 % w/w) containing different concentrations of activated carbon (0.1 % up to 0.5 % w/w). T...

Modeling studies for adsorption of phenol and co-pollutants onto granular activated carbon prepared from olive oil industrial waste

Granular activated carbon (OSAC) which was derived from olive oil industrial solid waste was chemically activated with different concentrations of phosphoric acid. OSAC-materials were evaluated for their ability to remove phenol from aqueous solution in a batch technique. Adsorption isotherms were determined and modeled with five linear Langmuir forms, namely the Freundlich, Elovich, Temkin, Ki...

Investigating the Effect of Using Oil, Natural Gas and Coal on Economic Growth of Iran

The purpose of this study is to investigate the role of oil, natural gas and coal consumption in Iran’s economic growth during the periods from 1980 to 2012. The stationary analysis is performed by using ADF and Phillips-Perron unit root test and Auto-Regressive Distributed Lag (ARDL) approach was used to test for co-integration between the variables. The findings show that the variables are co...
