chemical recycling of polycarbonate waste using conventional heating and microwave assisted method
پلی کربنات یکی از پلاستیکهای مهمی است که به صورت گسترده در تولید لوحهای فشرده، قطعات رایانه، مواد ساختمانی و غیره مورد استفاده قرار می گیرد. این پلیمر بصورت عمده از تراکم مونومر بیس فنولa (bpa) و کربنیل کلرید یا دی متیل کربنات ها بدست می آید. در سالهای اخیر بازیافت شیمیایی پلی کربنات بیشتر مورد توجه بوده است. بازیافت شیمیایی پلی کربنات برای بدست آوردن مواد اولیه آن با روشهای متفاوتی مانند تجزی...
Kinetic Modeling of Mass Transfer During Roasting of Soybeans Using Combined Infrared-Hot Air Heating
ABSTRACT: Roasting is one of the widespread methods for processing of nuts and beans that significantly enhances the flavor, color, texture and appearance of the products. In this research the kinetics and modeling of soybean roasting using combined infrared-hot air system and consumption of energy were investigated. The effect of the hot air temperature (160, 180 and 200 ºC), infrared powers (...
متن کاملEnhancing Oxidative Stability of Sunflower Oil during Convective and Microwave Heating Using Grape Seed Extract
This study was performed to investigate the effectiveness of grape seed extract (GSE) compared to butylated hydroxytoluene (BHT) on retarding lipid oxidation of sunflower oil subjected to convection and microwave heating up to 240 min under simulated frying conditions. The progress of lipid oxidation was assessed in terms of peroxide value (PV), p-anisidine value (p-AV), conjugated dienes and t...
متن کاملMicrowave heating
Microwave heating is a process within a family of electroheat techniques, such as induction, radio frequency, direct resistance or infra-red heating, all of which utilise specific parts of the electromagnetic spectrum. These processes supplement, and in specific cases totally replace, conventional heating or drying systems used in industry. This is because some conventional systems are very bul...
متن کاملHeat Transfer in Surface-Cooled Objects Subject to Microwave Heating
Several investigators in microwave bioeffects research have exposed biological preparations to intense microwave fields, while at the same time cooling the sample with flowing water. We examine the heat transfer characteristics of this situation, to estimate the maximum temperature increase and thermal time constants that might be encountered in such an experiment. The sample is modeled as a un...
