Abstract
<PICT:0590007/III/1> In a process for carrying out chemical reactions, especially the catalytic conversion of hydrocarbon oils, wherein contact particles are circulated between a reaction zone 10 and a regeneration zone 77, maintained at widely separated temperatures, spent particles from the reaction zone are passed through a heat-exchanging zone 63 in indirect heat exchange with hot regenerated particles. Oil introduced at 16 is mixed with regenerated particles from pipe 18, and passes to the reaction zone wherein the particles are maintained in a dense fluidized condition. Spent particles are withdrawn through stripping zone 42 and standpipe 48, and pass to the heat-exchanging zone mixed with regenerating gas from 62. The heated particles then pass through line 72 to the regenerator, when again a dense fluidized bed is maintained. Regenerated particles are withdrawn via trough 92 and standpipe 96 to the heat-exchanging zone and thence via line 106 to be mixed with fresh oil. The reaction temperature may be 800 DEG F. or below, the regeneration temperature 1000 DEG F. or above, and the solid/oil ratio 4/1 or higher. In the catalytic treatment of gasoline to improve the octane number, reaction is carried out at 750 DEG F., regeneration at 1150 DEG F., and the catalyst/oil ratio is about 10. 5/1 . Reference is also made to the catalytic cracking of light gas oil to form aviation gasoline.ALSO:<PICT:0590007/IV/1> In a process for carrying out chemical reactions, e.g. the treatment of gasolines to improve the octane number, wherein contact particles are circulated between a reaction zone 10 and a regeneration zone 77, maintained at widely separated temperatures, spent particles from the reaction zone are passed through a heat-exchanging zone 63 in indirect heat exchange with hot regenerated particles.
