Title: Catalyst and process for the dealkylation of aromatic hydrocarbons
Inventor: BETTS WELSLEY DONALD
IPC: C07C4/18
Filed: 1956-09-18
Abstract: Alkyl aromatic hydrocarbons are dealkylated by passing in vapour phase with hydrogen over an activated carbon catalyst at an elevated temperature.  The catalyst may also contain a metallic activator, e.g. 1-5 per cent of platinum or palladium. Temperatures of 450-700 DEG  C. may be used to above 40 atmospheres pressure with a molar ratio of hydrogen to alkyl aromatic of above 10:1.  Other hydrocarbons may be present and also sulphur-, oxygen- or nitrogen-containing impurities.  Sulphur compounds are split to hydrogen sulphide and gaseous hydrocarbons.  Naphthenic and paraffinic hydrocarbons are cracked with evolution of heat and it may therefore be preferable to remove non-aromatic hydrocarbons before treatment.  Benzene may be formed from toluene, benzene and toluene from polyalkyl benzenes and naphthalene from alkyl naphthalenes.

The reference axes X and Y are projected as an image by source 59, which image is split to form corresponding axes along the two given paths by the mirror 55. Each cell thus receives, as the mirrors rotate, two successive images, respectively of edge and axis, the three cells corresponding to the three given points, so that the three cells give signals corresponding to the three distances x 1 , x 2 , Y 1 . Positioning device circuit (Fig. 5).-The positioning of the chip is effected by three motors 71, 72, 73 controlled by the photocells 50, 51, 52 (see above). The two signals from cell 50 are passed to counter 93 so that the counter is started then stopped. The number of impulses between the two signals is a measure of x, and they are passed via pulse storage means 103 (which delays the pulses) to motor 71. Likewise, the two signals from cell 51 are passed to counter 94 and the corresponding impulses, which represent x 2 , are passed to motor 72 via pulse storage 104. Finally, the two signals from cell 52 are passed to counter 95 and then fed to motor 73 via pulse storage 105. In this way the three motors 71, 72, 72 are driven by an amount proportional to the relative measurements x 1 , x 2 , y 1  and thus displace the chip into the desired orientation.
