The metal in the second stage may be on a carrier having an intimate surface above 50 m.2/g.  The catalysts may be treated with sulphur-containing gases and then with hydrogen before they are used. The metal is preferably palladium, and the hydrocarbon is preferably free from hydrogen sulphide and readily decomposable organic sulphur compounds.  Preferred carriers are:-alumina, alumina-silica, alumina-chromia, low-silica bauxites, preferably thermally treated, magnesia, baria, calcium oxide, alkaline-earth metal carbonates, titania, zirconia or thoria.

Title: Radio navigation beacon

Filed: 1975-12-02
Abstract: 1496365 VOR system INTERNATIONAL STANDARD ELECTRIC CORP 2 Dec 1975 [11 Dec 1974] 49410/75 Heading H4D In a VOR system, false response of a receiver, tuned to one channel, to image frequencies arising from modulation harmonics of an adjacent channel is prevented by applying to the VHF carrier of a VOR ground station a characteristic amplitudemodulation additional to the usual modulations, thereby ensuring actuation of interference-rejecting circuitry in the receiver. The Fig. 4 embodiment of a ground station comprises a goniometer 4 and antennµ 5 and 6 for producing a cardioid VHF radiation pattern rotating at 30 Hz, plus an omni-directional pattern carrying speech modulation and a 30 Hz reference signal in the form of amplitude-modulation by a 9À96 kHz subcarrier itself frequency-modulated at 30 Hz. Part of the VHF signal is tapped off by a directional coupler 41, limited at 42 to remove the modulation, then amplitude-modulated at 43 by an FM signal centred on 50 kHz from a VCO 44. After gain adjustment at 46, 47 the resulting AM signal is fed to the antenna via coupler 41. Assuming a VOR channel spacing of 50 kHz, image frequencies may arise in one channel, corresponding to the 4th, 5th and 6th harmonics of the 9À96 kHz subcarrier of the adjacent channel. However, the FM signal centred on 50 kHz will also appear in that one channel and will be interpreted by the receiver's interference-rejection circuitry as a spurious signal, causing actuation of an alarm. In a modification of this embodiment (Fig. 5, not shown) the FM signal centred on 50 kHz is replaced by an FM signal centred on 47 kHz which is caused, by a phase-locked loop, to track the 30 Hz reference signal. A difference in frequency of #3 kHz thus occurs between the 47 kHz signal and the subcarrier 5th harmonic, so that an audible warning can be given of adjacentchannel interference.
