Definitions

  • Ne-123 This invention relates to'the manufacture of articles that by their nature are subjected in use to, and must withstand the attack of, gases that attack and remove carbon
  • the invention is par- 5 ticularly applicable to-themanufacture of appsratus' and parts thereof whichareused in the destructive hydrogenation ofoil and coal, or in .the synthesis of ammonia, and; with which hydrogen or mixtures of gases containing hydrogen in come into contact at high temperatures and'pressures. It is known to make such apparatus and parts thereof from so-called alloy steels containing chromium,'tungsten, molybdenum, or vanadium, andin somecases nickelalso.
  • the present in vention is not concerned with the apparatus or parts thereof used in cracking processes but with regard to the treatment of oil andicoal only with apparatus in which 011 and, coal are brought into reaction with hydrogen and the operation is carried on at high hydrogen partial pressures.
  • Tubes of external dlameterof 30 mm. and internal diameter of 12 mm. were made fromstee alloys ofthe following composition:- asi, 0.50% Mn, 0.0% Cr, 0.4 M6 and 0.50%
  • titanium content at least four times as great as the carbon contentso that the whole of the carbon is bound tothe titanium as titanium carbide: However, if smaller titanium contents are used there is still a substantialincrease in the resistance to hydrogen.
  • the steel alloys may contain besides titanium one or more ofthe elements silicon, manganese, nickel, cobalt, chromium. tungsten, molybdenum and vanadium, and the total content of these elements may amount to In general, however, atotal content of not more than 15% is found desirable. Even when these additional elements are present the titanium remains theprincipal factor in imparting resistance to loss of carbon, d this is particularly the case when the titanium content is at least four times as great asthe carbon content.
  • I5 1 It has been found particularly suitable to make vuse of steel alloys which contain carbon in an amount not exceeding 0.4%, titanium in an amount not exceeding 2%, and molybdenum'or vanadium or both in a total amount not exceeding 3%, with or without chromium in-an amount not exceeding 10%.
  • steel alloys For apparatus for' the. destructive hydrogenation of oil and coal as well as for'the synthesis of ammonia the following steel alloys may, for example, be used:-'
