[ 1 ] - Biodiesel: A Cost-effective Fuel Using Waste Materials
The main disadvantage of biodiesel is its high price. The price of biodiesel depends on various factors such as the price of oil, methanol, catalyst, and labor. Among dif-ferent economic factors, oil accounts for the largest share of input costs of biodiesel production. In this study, first, suitable heterogeneous catalysts were identified for biodiesel production. Several studies were carried ...
[ 2 ] - مدل‌سازی ترمودینامیکی تعادل فازی هیدرات گازهای تبریدی با استفاده از معادله‌حالت PRSV2
در این مقاله توانایی معادله حالت مکعبی PRSV2 برای پیش‌بینی فشار تشکیل هیدرات مبردهای کلرودی‌فلورومتان (R22)، تری‌فلورومتان (R23)، دی‌فلورومتان (R32)، پنتافلورواتان(R125)، 2،1،1،1-تترافلورواتان (R134a)، 1،1-دی‌فلورواتان (R152a) و کربن‌دی‌اکسید(R744) ...
[ 3 ] - Soybean Oil Transesterification Reactions in the Presence of Mussel Shell: Pseudo-First Order Kinetics
Calcium oxide is one of the appropriate catalysts for biodiesel production. In this study, cheap and compatible with environment catalyst has been used. Mussel shell of Persian Gulf coast is one of the sources of calcium carbonate that is converted to calcium oxide at calcination temperature up to 950°C. Transesterification reaction was carried out at optimum condition of our previous study...
