بوزدایی از fuel oil deodorization of fuel oil
مطالعات و بررسی های انجام گرفته نشان می دهد ترکیبات بودار موجود در fuel oil عمدتا ترکیبات سولفوردار سخت مثل تیوفن، دی متیل بنزوتیوفن و ... بوده و روشهای بوزدایی همچون استخراج با حلالهای اسیدی و بازی ، رقیق کاری با گازولین ، ماسکینگ با بوتیل استات نتایج چندان مطلوبی در بوزدایی از آن نشان نمی دهند.همچنین روش جذب سطحی برای بوزدایی fuel oil تنها با استفاده از جاذب هایی همچون بنتونیت و توفیت...
15 صفحه اولWater Management in the Cathode Side of a PEM Fuel Cell
A one dimensional isothermal mathematical modeling of cathode side of a Proton Exchange Membrane (PEM) fuel cell is developed for the water management problem. Water transport is investigated in both cathode Gas Diffusion Layer (GDL) and membrane through solving appropriate equations for fluid flow and mass transport in GDL and water transport within the membrane. The gaseous mixture flowing in...
متن کاملWater-balance Assessment in a Reformer/Fuel-cell System
Abstract. In PEM fuel cells pure hydrogen is used as a fuel. Due to its low density, the density of its stored energy is low, too. One of the possible solutions to the problem is production of hydrogen from the energy-reach material, e.g. methanol. Conversion of methanol to hydrogen is made with reformer in a steam reforming process in which besides methanol there is also water needed. On the o...
متن کاملWater dynamics and proton transfer in nafion fuel cell membranes.
The dynamics of water and its effect on proton transport kinetics in Nafion membranes are compared at several hydration levels. Nafion is the most widely used polyelectrolyte membrane in fuel cells. Ultrafast infrared spectroscopy of the O-D stretch of dilute HOD in H2O provides a probe of the local environment and hydrogen bond network dynamics of water confined in the hydrophilic regions of N...
