Pitt Greenville PGV Airport Overview. Pitt-Greenville Airport PGV, a small airport covering 872 acres, serves North Carolina's Pitt County, and is only two miles from the East Carolina University. PGV Airport is located outside the city of Greenville, off Route 13 (N. Carolina 903), and easily reachable by Interstate Hwys 40 & 95.
The Haber process or Haber-Bosch process is the primary industrial method used to make ammonia or fix nitrogen. The Haber process reacts nitrogen and hydrogen gas to form ammonia: N 2 + 3 H 2 â 2 NH 3 (Î´H = â92.4 kJÂ·mol â1).
Osmium is a much better catalyst for the reaction but is very expensive. This process produces an ammonia, NH 3 (g), yield of approximately 10-20%. The Haber synthesis was developed into an industrial process by Carl Bosch.The reaction between nitrogen gas and hydrogen gas to produce ammonia gas is exothermic, releasing 92.4kJ/mol of energy at 298K (25 o C).he hydrogen for the ammonia synthesis was made by the water-gas process (a Carl Bosch invention) which involves blowing steam through a bed of red hot coke resulting in the separation of hydrogen from oxygen. The nitrogen was obtained by distillation of liquid air, then by cooling and compressing air.
