An atomizing gas, such as steam, and a hot fluid comprising a hot liquid to be atomized, are passed under pressure, through separate fluid conduits in a heat exchange means, in which the hot liquid heats the steam to a superheat temperature, by indirect heat exchange. The superheated steam is then injected into the hot fluid, which comprises a two-phase fluid comprising steam and the hot liquid, subsequent to the superheated steam injection. The two-phase fluid is passed through an atomizing means, such as an orifice, into a lower pressure atomizing zone, which causes the steam to expand and atomize the liquid into a spray of liquid droplets. The two-phase fluid is formed before or as a consequence of the superheated steam injection and is preferably steam-continuous when passed through the atomizing means. This process is useful for atomizing a hot feed oil for a fluid cat cracking (FCC) process.

A process for reforming a naphtha feed at low severities with tin modified platinum-iridium catalysts. In particular, both high selectivity, and high activity are manifested by such catalysts in reforming a naphtha feed at low severities in the lead reactor, or reactors, of a series of reactors; i. e. , within the dehydrogenation and ring isomerization zone, or zones, of a reforming unit. The lead reactors of the series are charged with a tin-containing platinum-iridium catalyst, and the naphtha feed reformed to produce a low RON clear C. sub. 5 + liquid reformate. The low octane product of the lead reactors may be transferred to a mogas pool, into blending components, or all or some part of the product further reformed. Preferably, the product is further reformed in a tail reactor, and preferably the tail reactor is charged with a non-tin containing platinum, or platinum-iridium catalyst.

A process for producing polymers from olefins selectively produced by a two stage process for selectively producing C. sub. 2 to C. sub. 4 olefins from a gas oil or resid is disclosed herein. The gas oil or resid is reacted in a first stage comprising a fluid catalytic cracking unit wherein it is converted in the presence of conventional large pore zeolitic catalyst to reaction products, including a naphtha boiling range stream. The naphtha boiling range stream is introduced into a second stage comprising a process unit containing a reaction zone, a stripping zone, a catalyst regeneration zone, and a fractionation zone. The naphtha feed is contacted in the reaction zone with a catalyst containing from about 10 to 50 wt. % of a crystalline zeolite having an average pore diameter less than about 0. 7 nanometers at reaction conditions which include temperatures ranging from about 500 to 650. degree. C.

A process wherein, in a series of reforming zones, or reactors, each of which contains a bed, or beds of catalyst, the catalyst in the leading reforming zones is constituted of supported platinum and a relatively low concentration of rhenium, and the catalyst in the last reforming zone, or reactor of the series, is constituted of platinum and a relatively high concentration of rhenium. The amount of rhenium relative to the platinum in the last reforming zone, or reactor is present in an atomic or weight ratio of rhenium:platinum of at least about 1. 5:1; preferably at least about 2:1, and more preferably ranges from about 2:1 to about 3:1. The beds of catalyst are contacted with a hydrocarbon or naphtha feed, and hydrogen, at reforming conditions to produce a hydrocarbon, or naphtha product of improved octane, and the product is withdrawn.

The propylene production of a fluid catalytic cracking unit employing a large pore zeolite cracking catalyst, produces more propylene by adding a naphtha cracking riser and a medium pore zeolite catalytic component to the unit, and recycling at least a portion of the naphtha crackate to the naphtha riser. The large pore size zeolite preferably comprises a USY zeolite and the medium pore size is preferably ZSM-5. Propylene production per unit of naphtha feed to the naphtha riser is maximized, by using the 60-300° F. naphtha crackate as the feed.

This invention relates to a short contact time (SCT) fluid catalytic cracking (FCC) process for improving the yield of distillates and gasoline. An SCT FCC process combines staging the FCC conversion process with interstage molecular separation of multi-ring aromatic species wherein separation of cat bottoms and recycling the separated stream containing saturates and 1- and 2-ring aromatics to the FCC unit results in improved yields of gasoline and other distillates while decreasing bottoms yields.

A FCC process in which spent catalyst is stripped of hydrocarbon in a stripping zone prior to entering the regenerator. In order to maximize the amount of strippable hydrocarbon removed in the stripping zone with minimal use of stripping gas, a sample of spent catalyst is removed prior to entering the regenerator. The spent catalyst is analyzed for strippable hydrocarbon by conducting the sample to a heated catalyst collection vessel, evacuating the catalyst, collecting the gases from the collection vessel and analyzing the gases for amount of strippable hydrocarbon on the spent catalyst.
