The most common oxide of vanadium, vanadium pentoxide V 2 O 5, is used as a catalyst in manufacturing sulfuric acid by the contact process and as an oxidizer in maleic anhydride production.
22.
Because light does not pass any significant distance through the air or through lenses in going from the negative to the print, the contact process ideally preserves all the detail that is present in the negative.
23.
The hydrogen sulfide removed and recovered by the amine gas treating unit is subsequently converted to elemental sulfur in a Claus process unit or to sulfuric acid in a wet sulfuric acid process or in the conventional Contact Process.
24.
The formation and constitution ( physique ) of plastic zones around penetrating objects are arguably a prerequisite and the main factor for excessive material transfer, lump growth, and galling build-up even in the initial contact process.
25.
The material to be heated ( a non-metal ) can therefore simply be placed in the path of the waves, and heating takes place in a non-contact process which does not require capacitative conductive plates.
26.
For any \ scriptstyle d, \ mathcal { N } and \ scriptstyle T, if the threshold contact process with \ scriptstyle \ lambda = 1 has a nontrivial invariant measure, then the threshold voter model coexists.
27.
:The contact process is so called because it involves the " contact " of the heated sulphur dioxide and oxygen with Vanadium ( V ) oxide ( a catalyst ) to form sulphur trioxide far more efficiently than any earlier processes.
28.
It is thus a contact process or near-contact process, since it usually sandwiches the material to be heated ( usually a non-metal ) between metal plates taking the place of the dielectric in what is effectively a very large capacitor.

The combustion gases are cooled to the converter inlet temperature of about 420 440 �C . To process these wet gases in a conventional cold-gas contact process ( DCDA ) plant would necessitate cooling and drying of the gas to remove all moisture.
