    摘要: A process for catalytic production of olefins comprises contacting a first hydrocarbon stream and a first stream of fluid catalyst in a first riser to produce a first cracked product stream and a spent catalyst stream. The first cracked product stream is separated in a main column. An overhead stream from the main column is separated into a second hydrocarbon stream. The second hydrocarbon stream is contacted with a second stream of fluid catalyst in a second riser to produce a second cracked product stream and a first stream of cool catalyst. A third hydrocarbon stream is obtained from the overhead stream and/or from the second cracked product stream. The third hydrocarbon stream is contacted with a third stream of fluid catalyst in a third riser to produce a third cracked product stream and a second stream of cool catalyst.

    摘要: The present invention relates to a device that installs in-line in the fuel supply line of fuel usage equipment such as a HVAC system or a large commercial natural gas or diesel generator. The device is suitable for use with liquid or gas hydrocarbon fuels such as gasoline, diesel, propane, or natural gas. The device consists of a hollow cylinder with male ends and that contains a tightly packed copper wire core. The copper wire serves as a catalyst to crack the fuel's carbon chain molecules as the fuel flows through the device. The resulting fuel contains more and shorter fuel molecules, has a higher vapor pressure and burns more efficiently in the vehicle's engine. The copper wire is held in place by perforated copper keepers and the keepers are secured within the cylinder by snap rings that engage circumferential grooves provided internally at the ends of the cylinder.

    摘要: The present invention discloses a process optimizing the yield of ethylene and propylene from a fluid catalytic cracking unit. The method combines a first catalytic reactor, a fractionation zone, a separation unit and a second catalytic reactor. The separation unit produces a first separate stream comprising C4 olefins and a second separate stream comprising C5 olefins. The separate streams may be combined and are passed to a second catalytic reactor for additional conversion to ethylene and propylene.

    摘要: Methods and systems. For producing diesel arc provided. The method for producing diesel can include cracking a first hydrocarbon feed in a first riser under first cracking conditions to provide a first effluent containing a first light cycle oil, a heavy cycle oil, and a first bottoms and Fractionating at least a portion of the first effluent to separate the first bottoms and the heavy cycle oil from the first light cycle oil. The method can include cracking the separated first bottoms in a second riser under second cracking conditions to produce a second effluent containing a second light cycle oil and a second bottoms. The method can also include cracking the separated heavy cycle oil in the first riser under third cracking conditions to provide a third effluent and mixing the third effluent with the first hydrocarbon feed to provide the first cracking conditions.

    摘要: A process and catalyst for improving the yield of propylene from residual oil feedstock includes obtaining residual oil feedstock from a vacuum distillation tower. The residual oil feedstock has contaminant metals such as sodium or vanadium. The residual oil feedstock is contacted with a cracking catalyst in a catalytic cracking zone to make products. A ZSM-5 zeolite, a binder, a filler and a metal trap are components of the cracking catalyst. The metal trap has a trapping agent in an outer shell of the catalyst, a trapping agent in the ZSM-5 binder or combinations thereof. After reacting, the cracking catalyst is separated from the products in a separator zone, then regenerated by combusting coke deposited on a surface of the cracking catalyst in an oxygen-containing environment. The cracking catalyst is returned to the catalytic cracking zone. The catalyst with the metal trap is also disclosed.
