چکیده
Global demand for both clean energy carriers and agricultural nutrients continues to grow rapidly, alongside increasing quantities of waste globally, interlinked challenges that may be addressed with solutions. We report on the potential efficiency Greenhouse Gas (GHG) intensity several configurations a new, sustainability-driven ammonia (NH 3 ) production processes determine whether waste-based process designed first around carbon dioxide (CO 2 capture can compete other available NH technologies. This is assessed via different scenarios: Two hydrogen generating options are paired four CO fates. For either an anaerobic digestion-centered or two-stage dark fermentation coupled digestion process, resultant captured injected, sold marketplace, released directly in atmosphere, converted urea order produce green substitute synthetic . Modeled yields range from 47 t when captured, 3.8 76.5 system no unutilized Among technologies assessed, where digestion-only most efficient GHG emissions water consumption, while requires less fertilizer-N basis. approximately 8% lower than two-stage. The best proposed technology consumes about 41% electrolysis Haber-Bosch 27% Steam Methane Reforming (SMR) per kg

Butanol production from food waste: a novel process for producing sustainable energy and reducing environmental pollution
BACKGROUND Waste is currently a major problem in the world, both in the developing and the developed countries. Efficient utilization of food waste for fuel and chemical production can positively influence both the energy and environmental sustainability. This study investigated using food waste to produce acetone, butanol, and ethanol (ABE) by Clostridium beijerinckii P260. RESULTS In contro...
متن کاملa study on the design of bio-ethanol process from date wastes of sistan and baluchistan province
اتانول کاربردهای متنوعی در صنایع لاستیک سازی، رنگسازی، حلالها ومکمل سوخت خودرو دارد. اتانول برخلاف نفت از جمله مواد تجدیدپذیر محسوب می شود که مشکلات زیست محیطی و آلودگی نیز ایجاد نمی کند. استفاده از اتانول به عنوان مکمل سوختخودروها از جمله مهمترین مصارف صنعتی این ماده بشمار می رود. با توجه به این موضوع تحقیق و توسعه در زمینه تولید اتانول با درجه خلوص بالا در سطح جهان، و نه تنها در کشور های پیشر...
simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
wuthering heights and the concept of marality/a sociological study of the novel
to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...
