摘要： A multistage process for producing isoalkyl ethers from lower aliphatic oxygenate feedstock, such as methanol. Feedstock is catalytically converted in a primary catalyst stage at elevated temperature in contact with zeolite catalyst to predominantly C.sub.2 -C.sub.7 lower olefins comprising isobutylene and isoamylene, by-product water and a minor amount of C.sub.8.sup.+ hydrocarbons, followed by fractionation of the C.sub.2 -C.sub.7 olefins to recover a C.sub.2 -C.sub.3 -rich recycle stream for further catalytic conversion in the primary stage. C.sub.4 -C.sub.7 olefins are passed to a second catalytic etherification stage for reaction of isoalkenes with methanol to produce methyl tertiary-butyl ether, methyl isoamylether and higher isoalkyl ethers. The second stage effluent may be fractionated to recover an ether product, C.sub.5.sup.+ hydrocarbon liquid product, and unreacted butenes. Advantageously, the unreacted butenes are further reacted with isoparaffin in a third catalytic stage under acid catalysis alkylation conditions, and fractionated to recover C.sub.6.sup.+ alkylate liquid, liquid hydrocarbon product. The ethers may be blended with at least one C.sub.6.sup.+ hydrocarbon to produce high octane gasoline.

摘要： A fluid catalytic cracking (FCC) apparatus and process comprising a reactor riser zone, a primary and a secondary cyclones, connected in series to the riser zone, and a stripping zone. The riser zone, the primary and the secondary cyclones, and the stripping zone, are placed within a single reactor vessel. The primary cyclone is connected to the reactor riser zone by an enclosed conduit which prevents random post-riser thermal cracking of the hydrocarbons after they exit the reactor riser zone. The conduit contains a trickle valve, or other means, to accommodate sudden increased surges of flow of the hydrocarbons and catalyst mixture.

摘要： A component mapper is provided in connection with a process wherein a fluid stream having multiple physical components is modeled as a plurality of pseudo-components. Each physical component has a boiling point, and each pseudo-component has a pre-defined boiling point and includes all physical components from the fluid stream having approximately the pre-defined boiling point. Each pseudo-component in the model of the fluid stream has a varying pre-defined property and a varying amount. A plurality of sub-pseudo-components are defined for each pseudo-component such that the pseudo-component is replaceable therewith. Each sub-pseudo component has the pre-defined boiling point of the pseudo-component, a pre-defined value for the pre-defined property, and a varying amount. For each pseudo-component, a current value of the pre-defined property and a current amount of the pseudo-component are obtained, and a current amount for each sub-pseudo-component of the pseudo-component is then calculated. The pre-defined value of the pre-defined property and the calculated current amount for each sub-pseudo-component of each pseudo-component are then utilized in a real-time optimization process. In one embodiment of the present invention, the pre-defined property is density, and the amount is percentage weight and percentage volume.

摘要： A process has been discovered for the conversion of C.sub.5 -C.sub.7 olefinic hydrocarbons, such as those contained in FCC light naphtha, to iso-butene-rich and isoamylene-rich streams in an integrated process for the production of MTBE and TAME. The process involves the initial separation of the isoamylene-rich C.sub.5 -fraction of the feedstream which is converted to TAME. The C.sub.6 -C.sub.7 fraction plus unreacted C.sub.5 's are converted by olefin interconversion with medium pore zeolite catalyst into an isobutylene and isoamylene-rich stream which is then used as feedstream for etherification to MTBE and TAME.

摘要： An FCC catalyst regeneration technique in which the catalyst is regenerated in a dense bed regenerator. Regeneration effluent gases are collected from different parts of the regenerator vessel in a common collection zone and passed through the catalyst separation cyclones from the common collection zone. The cyclones may be arranged with their inlet horns adjacent one another in the common collection zone or a cyclone inlet manifold with a common inlet may be connected to the cyclone inlets. The inlet port to the manifold may be extended to form an elongated vertical duct through which regeneration effluent gases and entrained catalyst pass from the dilute phase of the dense bed to the cyclone so that mixing of the effluent gases is promoted to ensure combustion in residual quantities of oxygen present in the effluent gases before the gases enter the cyclones. Improved operating flexibility is obtained together with a reduced likelihood of cyclone damage as a result of localized high temperature excursions. In addition, the NO.sub.x level of the regenerator stack gases is reduced.
