20130137907 | PROCESS FOR THE PRODUCTION OF MIDDLE DISTILLATE FROM A CONVENTIONAL HEAVY FEEDSTOCK INCLUDING A STEP FOR SELECTIVE HYDROGENATION OF THE EX FCC HCO CUT - The present invention describes a process for the conversion of a heavy feedstock for improving the production and selectivity for middle distillate, said process using a catalytic cracking unit followed by a unit for selective hydrogenation of the heavy distillate cut (HCO) or any other cut rich in triaromatic compounds before recycling it to the FCC reaction zone in order to maximize the middle distillate cut. | 05-30-2013 |
20130152791 | PROCESS FOR CATALYTIC CRACKING ASSOCIATED WITH AN AMINE TREATMENT UNIT WITH IMPROVED CO2 BALANCE - The present invention describes a process for catalytic cracking associated with a unit for amine treatment of regeneration fumes from the catalytic cracking unit, which process uses at least one counter-pressure turbine to operate the cracked gas compressor and/or the regenerative air blower which can be used to improve the CO | 06-20-2013 |
20130211161 | PROCESS FOR CONVERTING A HEAVY FEED USING A CATALYTIC CRACKING UNIT AND A STEP FOR SELECTIVE HYDROGENATION OF THE GASOLINE OBTAINED FROM CATALYTIC CRACKING - The present invention describes a process for converting a heavy feed which is flexible for the production of propylene, gasoline and middle distillate. | 08-15-2013 |
20130281749 | PROCESS FOR CONVERTING A HEAVY FEED INTO MIDDLE DISTILLATE - The present invention describes a process for the conversion of a heavy feed which can be used to improve the selectivity for middle distillate. The process employs a catalytic cracking unit followed by one or more units for the oligomerization of C2 to C9 olefins which can preferentially produce an additional cut termed the middle distillate. The light portion of the oligomerate produced which cannot be incorporated into the middle distillate cut is recycled to the FCC unit for cracking into light olefins which are returned to the oligomerization units as a supplement to the olefins of the feed in order to preferentially form heavy oligomerates which can be incorporated into the middle distillate cut. | 10-24-2013 |
