Title: Method of synthesis of ammonia
Inventor: JAKOBSEN KLAUS I KH
IPC: C01C1/04
Filed: 1999-07-01
Granted: 2002-09-20
Abstract: FIELD: chemical technology. SUBSTANCE: invention relates to a method of synthesis of ammonia by catalytic conversion of gas-synthesis. Method of synthesis of ammonia involves interaction of gas-synthesis consisting of hydrogen and nitrogen that is passed through a layer of catalyst for ammonia synthesis placed in an immobile layer where an immobile layer comprises catalyst particles for ammonia synthesis of size in the range from less 1.5 mm to 0.2 mm or above taken in the mass ratio = (40-70):(10-40):(10-30), respectively. The catalyst volume density is increased in using catalyst particles of size in the range less 1.5 and to 0.2 mm or above and in their content in layer in the claimed mass ratio at least wt.% that results to high pressure drop over the catalyst layer and improved distribution of gas-synthesis flow in the layer. EFFECT: improved method of synthesis. 3 cl, 1 tbl
