    摘要： Methods and apparatuses are provided for cracking a hydrocarbon. The method includes contacting a first hydrocarbon stream with a first cracking catalyst at a first cracking temperature in a first riser to produce a first riser effluent and a first spent catalyst. A second hydrocarbon stream is contacted with a second cracking catalyst at a second cracking temperature in a second riser to produce a second riser effluent and a second spent catalyst, where the second cracking temperature is less than the first cracking temperature. The first riser effluent and the second riser effluent are combined to produce a mixed riser effluent, and the mixed riser effluent is fractionated in a fractionation zone to produce a light cycle oil. The first spent catalyst and the second spent catalyst are combined in a reactor to produce a mixed spent catalyst.

    摘要： A hydrocarbon feed is passed to a first zone of a vaporization unit to separate a first vapor stream and a first liquid stream. The first liquid stream is passed to a second zone of the vaporization unit and contacted with a counter-current steam to produce a second vapor stream and a second liquid stream. The first vapor stream and the second vapor stream are cracked in the radiant section of the steam cracker to produce a cracked effluent. The second liquid stream is catalytically cracked to produce a cracked product. The cracked product is distilled to produce an overhead stream, a light cycle oil, and a heavy cycle oil. The light cycle oil is reacted with hydrogen in the presence of a catalyst to produce a hydrotreated light cycle oil. The hydrotreated light cycle oil and the overhead stream are fed to the vaporization unit.

    摘要： A process is described for maximizing the FCC middle distillates comprising the use of two different converters, operating in a coordinated manner that seeks to maximize the production of LCO for diesel, generating a specified gasoline and reducing fuel oil production. Converter “A” operates with a low contact time in the riser, of 0.2 to 1.5 sec. (preferably from 0.5 to 1.0 sec.) making a higher reaction temperature possible even at low severity, from 510° C. to 560° C. (preferably from 530° C. to 550° C.) and with a catalyst suitable to the maximization of LCO. Converter “B” possesses a high activity catalytic system, suited to cracking naphtha and DO generated in the first converter. Preferably, converter “B” has two separate risers, allowing the reaction temperatures of each to be adjusted independently according to the range most recommended for maximizing the cracking of each of the streams: 530° C. to 560° C. for the DO riser and 540° C. to 600° C. for the naphtha riser. The high-quality LCO stream generated by cracking at low severity in converter “A” is not contaminated by the poorer quality LCO generated by re-cracking the DO in converter “B,” since each converter has its own fractionating tower. The use of low contact time as a route for reducing severity in converter “A” geared towards the production of better quality LCO allows it to operate with a higher reaction temperature for the same LCO conversion and quality level, entailing greater operating reliability for the unit, and providing benefits for the heat balance of the converter. In existing units, the improvement in the heat balance provides leeway to the air blower via increased batch temperature, and makes room for processing more residual batches.

    摘要翻译： 描述了一种最大化FCC中间馏分的方法，其包括使用两种不同的转化器，以协调的方式运行，其寻求最大化柴油的LCO生产，产生特定的汽油和减少燃料油的生产。 转换器“A”在提升管中的接触时间低，为0.2至1.5秒。 （优选为0.5至1.0秒），甚至在较低的苛刻度下也可以使用更高的反应温度，从510℃至560℃（优选530℃至550℃）和适合于 LCO最大化。 转化器“B”具有高活性催化系统，适用于在第一转化器中产生的石脑油和DO。 优选地，转化器“B”具有两个单独的提升管，允许每个反应温度根据最适合使每个流的最大化的范围独立地调节：对于DO提升管为530℃至560℃ 对于石脑油提升管为540℃至600℃。 由于每个转换器都有自己的分馏塔，所以在转换器“A”中以低严重程度开裂产生的高质量LCO流不会被转换器“B”中的DO重新开裂所产生的较差的质量LCO所污染。 使用低接触时间作为降低转换器“A”的严重性的路线，用于生产更好质量的LCO，使其能够在相同的LCO转换和质量水平下以更高的反应温度运行，从而为该单元提供更高的运行可靠性 ，并为转换器的热平衡提供益处。 在现有单元中，热平衡的改善通过增加批量温度为鼓风机提供了余地，并且为处理更多的剩余批次提供了空间。
