OSTI ID:6338682
Raney Nickel, a commercially available powdered nickel-aluminum catalyst, has been flame-sprayed onto various stainless steel shapes used in methanation reactors for the purpose of developing a process to make synthetic natural gas (methane, CH/sub 4/) from 3:1 synthesis gas (3H/sub 2/ + 1CO) produced in a coal gasifier. The flame spray equipment used is commercially available and the spray parameters selected are essentially conventional, but some equipment modifications and variations in spray techniques have been made to produce acceptable coated reactor surfaces. Examination of the coatings shows that a multi-phase structure of Ni/sub 2/Al/sub 3/, NiAl/sub 3/ and a eutectic of Ni/sub 2/Al/sub 3/ and ..cap alpha..-aluminum is deposited.
