ammonia synthesis at low pressure

अमोनिया एक अमोनिया चयनात्मक शोषक के उपयोग से कम दबाव में संश्लेषित किया जा सकता है । प्रक्रिया पवन ऊर्जा के साथ संचालित किया जा सकता है, सिंथेटिक उर्वरक के लिए अमोनिया की आवश्यकता क्षेत्रों में स्थानीय रूप से उपलब्ध है । इस तरह की पवन ऊर्जा अक्सर कहा जाता है "असहाय," क्योंकि यह केवल जनसंख्या केंद्रों जहां यह सीधे इस्तेमाल किया जा सकता से दूर उपलब्ध है ।
प्रस्तावित कम दबाव की प्रक्रिया में, नाइट्रोजन हवा से दबाव स्विंग अवशोषण का उपयोग कर बनाया है, और हाइड्रोजन पानी की इलेक्ट्रोलिसिस द्वारा उत्पादित है । जबकि इन गैसों लगभग ४०० डिग्री सेल्सियस पर एक पदोंनत पारंपरिक उत्प्रेरक की उपस्थिति में प्रतिक्रिया कर सकते हैं, रूपांतरण अक्सर रिवर्स प्रतिक्रिया है, जो इस प्रतिक्रिया केवल उच्च दबाव में व्यवहार्य बनाता द्वारा सीमित है । यह सीमा एक ammine कैल्शियम या मैग्नीशियम क्लोराइड की तरह पर अवशोषण द्वारा हटाया जा सकता है । इस तरह क्षारीय धातु halides प्रभावी रूप से अमोनिया को दूर कर सकते हैं, इस प्रकार प्रतिक्रिया के संतुलन की कमी को दबा । प्रस्तावित अवशोषण-बढ़ाया अमोनिया संश्लेषण प्रक्रिया में, प्रतिक्रिया की दर तो रासायनिक कैनेटीक्स और न ही अवशोषण की दर से नियंत्रित किया जा सकता है, लेकिन unactioned गैसों के रीसायकल की दर से । परिणाम एक पारंपरिक छोटे पैमाने Haber-बॉश प्रक्रिया से बने अमोनिया के साथ अनुकूल तुलना करें ।
