Independently selecting heat variables of 40 °C, 50 °C, 60 °C, 70 °C, and 80 °C, the temperature profiles, drying curves, thermal efficiency and effectiveness, and energy and exergy were analyzed to meet the standardized moisture content of the product as well as other features (color, vitamin C content, and β-carotene content). It was found that the drying rate decreased when the temperature rose, while the drying chamber efficiency and drying effectiveness were inversely proportional to the duration. The collector became the most efficient at 40 °C. The drying air temperature is directly proportional to utility, energy efficiency, exergy input, exergy ouput, exergy loss, exergetic efficiency, and development potential while inversely proportional to the energy utilization ratio. Drying red pepper with a hybrid solar dryer at all observed temperatures was deemed a...

In addition, this type of FAS is a biodegradable surfactant. Surfactant is the basic ingredient of some cleaning products such as bath soap, facial wash soap, and liquid soap. There are two methods commonly used to produce higher alcohol than commercial ones: high-pressure hydrogenation and reduction with sodium metal.
