Stepwise methane steam reforming: a route to CO-free hydrogen

A method for the production of clean hydrogen is demonstrated. The process consists of two steps involving the decomposition of methane to CO-free hydrogen and surface carbon in the first step followed by steam gasification of this surface carbon in the second step. This process can be operated in cycles and could be an excellent hydrogen source for fuel cells and other devices or processes req...

translating allusive devices:a survey of a portrait of the artist as a young man by james joyce

تلمیح یکی از عناصری است که تقریباً در همه ی متون ادبی یافت و باعث ایجاد شکاف های فرهنگی می شود. در این تحقیق به عنوان شکلی از بینامتنیت در ترجمه مورد توجه قرار می گیرد. تلاش شده است تا راهکارهای مترجمان برای ترجمه چهار نوع اسامی خاص و عبارات کلیدی تلمیحی (مذهبی، سیاسی، تاریخی و اسطوره ای) موجود در رمانِ چهره مرد هنرمند در جوانی به فارسی بررسی شود. این تحقیق مقایسه ای بر اساس راهکارهای ترجمه تلمیح...

CO-Free Production of Hydrogen via StepwiseSteam Reforming of Methane

CO-free hydrogen is produced by the reversible cyclic stepwise steam reforming of methane for use in fuel cells and other processes that are sensitive to CO poisoning. The process consists of two steps involving the decomposition of methane in a first step followed by steam gasification of the surface carbon in a second step. The ease of carbon removal in step II is strongly dependent on temper...
