  • Patent number: 8323477
    Abstract: A process for mixing regenerated and carbonized catalyst involves obstructing upward flow of catalyst by one or more baffles between a catalyst inlet and a feed distributor. Each catalyst stream may be passed to opposite sides of a riser. Baffles obstruct upward flow to effect mixing of regenerated and carbonized catalyst to obtain a more uniform temperature and catalyst mixture before contacting the feed.

  • Patent number: 8231775
    Abstract: A process and apparatus is disclosed for converting heavy hydrocarbon feed into lighter hydrocarbon products. The heavy hydrocarbon feed is slurried with a particulate solid material to form a heavy hydrocarbon slurry and hydrocracked in a slurry hydrocracking unit to produce vacuum gas oil (VGO) and pitch. A first vacuum column separates VGO from pitch, and a second vacuum column further separates VGO from pitch. As much as 15 wt-% of VGO can be recovered by the second vacuum column and recycled to the slurry hydrocracking unit. A pitch composition is obtained which can be made into particles and transported without sticking together.

  • Patent number: 8231847
    Abstract: An apparatus is disclosed for recovering product from catalytically converted product streams. Gaseous unstabilized naphtha from an overhead receiver from a main fractionation column is compressed in a compressor. Liquid unstabilized naphtha from the overhead receiver and liquid naphtha fraction from the compressor are sent to a naphtha splitter column upstream of a primary absorber. Consequently, less naphtha is circulated in the gas recovery system.

  • Patent number: 8231778
    Abstract: Methods are disclosed for hydrocracking processes that convert a significant portion of a heavy hydrocarbon feedstock such as vacuum gas oil (VGO) to lower molecular weight, lower boiling hydrocarbons. In addition to molecular weight reduction, the processes also substantially reduce the pour point of a recovered higher boiling fraction or unconverted oil, all or a portion of which may be used as a lube base stock, optionally after one or more further treatment steps such as hydrofinishing. The ability to reduce the pour point, through hydroisomerization, of the higher boiling fraction greatly improves the quality of this fraction, or unconverted oil, for use in lube base stock preparation. Advantageously, separate, conventional hydroisomerization and/or dewaxing steps, often requiring a noble metal catalyst, may be avoided in particular embodiments disclosed herein.

  • Patent number: 8197677
    Abstract: One exemplary embodiment can be a system for separating a plurality of naphtha components. The system can include a column, an overhead condenser, and a side condenser. Generally, the column includes a dividing imperforate wall with one surface facing a feed and another surface facing at least one side stream. Typically, the wall extends a significant portion of the column height to divide the portion into at least two substantially vertical, parallel contacting sections. Typically, the overhead condenser receives an overhead stream including a light naphtha from the column. Usually, a side condenser receives a process stream from the column and returns the stream to the column to facilitate separation. A cooling stream may pass through the overhead condenser and then the side condenser.
