The reaction has been used as amethod of fixing nitrogen in countriesin which cheap electricity isavailable to make the calcium dicarbide(the cyanamide process). Calciumcyanamide can be used as afertilizer because it reacts with waterto give ammonia and calcium carbonate:CaCN2(s) + 3H2O(l)→...
The calcium looping process (CLP) is one of the clean coal technologies being developed for the production of hydrogen (H2) and electricity from coal-derived syngas. It integrates the watergas shift reaction with in situ carbon dioxide (... S Ramkumar,LS Fan - 《Energy & Fuels》 被引量:...
1. Calcium chloride is generated by the reaction of sodium chloride and calcium hydroxide, and the water is removed by dehydration treatment to obtain anhydrous calcium chloride; 2. It is prepared by concentrating and dewatering calcium chloride solution in salt lake resources....
The shell powders were heated at calcination temperatures of 550 °C, 700 °C and 900 °C for 5 h in a furnace (Nabertherm P330, Germany) to obtain the calcined powder. The chemical reaction occurring during the calcination process is shown by the chemical reaction below (1).(1)CaCO3→...
