Abstract: Furnace black (I) has a hydrogen (H) content of over 4000 ppm, determined by CHN analysis, and peak integral ratio less than 1.22, determined by inelastic neutron scattering (INS) of unconjugated H atoms (1250-2000 cm ) to aromatic and graphitic H atoms (1000-1250 cm and 750-1000 cm ). An Independent claim is also included for the production of (I).

Abstract: Electrocatalyst which are formed of a carbon support, which is a carbon black with an H content of >4000 ppm and, as the catalytically active component, platinum or bi- or multi-metallically doped or alloyed platinum. The electrocatalysts are prepared by deposition of noble metals on the carbon black surface. They can be used for the production of fuel cells.

Abstract: A specific form of surface coating of Al2O3 catalysts, using additional amounts of aluminium ions and minimum amounts of platinum ions, made it possible to use Al2O3 as a catalyst for long-term operation (150 days and more) in the preparation of hydrogen cyanide from hydrocarbons and ammonia, preferably in the BMA process.

Abstract: Prodn. of HCN under the conditions of the 'HCN-CH4-NH3' process, involves reacting 1-4 C aliphatic hydrocarbons (I) with NH3 in the presence of a catalyst (II). The novel features are that : (a) reaction is carried out initially with a catalyst precursor (IIA), consisting of alumina mouldings with Al ions and very small amts. of noble metal, pref. Pt ions applied to the surface from soln.; (b) (IIA) is dried and reduced with H2 before use; (c) (IIA) is placed in the HCN reactor, which is heated to 1000-1350 deg.C and charged with the usual mixt. of NH3 and (I) for this reaction, which is initiated by (IIA); and (d) after a short time, reaction is continued with the Al nitride film formed in situ on the surface of (IIA). Pref. (I) is CH4. (II) is a pref. tubular moulding prepd. from alpha-alumina by impregnation with H2PtCl6 soln. (pref. contg. 0.5-5 wt.% Pt ions) and an AlCl3, Al(NO3)3 or Al2(SO4)3 soln., pref. using a noble metal (Pt):Al molar ratio of 0.001-0.1:1, esp. 0.01-0.1:1.
