Title: Process for the catalytic pressure refining of crude benzene
IPC: C07C7/163
Filed: 1957-06-20
Abstract: In the refining of crude benzene under elevated temperature and pressure in the presence of an oxide or sulphide of a Group V, VI or VIII metal with a hydrogen-containing gas, the preheated mixture of hydrocarbon vapour and hydrogen-containing gas is subjected to a sudden change in the direction and a reduction in the velocity of flow and the cokelike dust thereby separated is carried away by a small proportion of the mixture.  The refining process may be effected at 15-100 atmospheres <PICT:0862214/IV (b)/1> and 200-420 DEG  C.  The preheated reaction mixture enters the catalyst chamber 1 by inlet 4 and separating chamber 5.  The gas enters the chamber 5 through slots 6 where the direction of flow is abruptly changed and the flow velocity is reduced.  The gases enter the catalyst chamber through holes 7.  A small proportion of the gases may be removed by pipe 9 from time to time, regulated by valve 14.  The component passes through holes 12 in the jacket 10 surrounding pipe 9 and is directed upwardly into pipe 9 by passages 13, thereby entraining coke dust from the bottom of the separator.  Coke may be separated from the gas stream which is then recycled.
