Abstract:
A divided wall column can allow for fractionation of multiple streams while maintaining separate product qualities. Effluents from multiple stages of a reaction system can be processed in a single divided wall column. The divided wall column can produce multiple cuts from each separated area, as well as at least one output from a common area. At least one reaction stage can advantageously have a continuous liquid phase environment.
Abstract:
Hydrocarbon feeds can be hydrotreated in a continuous gas-phase environment and then dewaxed in a liquid-continuous reactor. The liquid-continuous reactor can advantageously be operated in a manner that avoids the need for a hydrogen recycle loop. A contaminant gas can be added to the hydrogen input for the liquid-continuous reactor to modify the hydrogen consumption in the reactor.
Abstract:
An integrated process for producing naphtha fuel, diesel fuel and/or lubricant base oils from feedstocks under sour conditions is provided. The ability to process feedstocks under higher sulfur and/or nitrogen conditions allows for reduced cost processing and increases the flexibility in selecting a suitable feedstock. The sour feed can be delivered to a catalytic dewaxing step without any separation of sulfur and nitrogen contaminants. The integrated process includes an initial dewaxing of a feed under sour conditions, optional hydrocracking of the dewaxed feed, and a separation to form a first diesel product and a bottoms fraction. The bottoms fraction is then exposed to additional hydrocracking and dewaxing to form a second diesel product and optionally a lubricant base oil product. Alternatively, a feedstock can be hydrotreated, fractionated, dewaxed, and then hydrocracked to form a diesel fuel and a dewaxed, hydrocracked bottoms fraction that is optionally suitable for use as a lubricant base oil.

The gasoline composition contains (a) a major amount of a mixture of hydrocarbons in the gasoline boiling range and (b) a minor amount of at least one hydrocarbon having 5 to 12 carbon atoms and containing at least one cyclopropyl group and at least one acetylenic group.
Abstract:
The invention provides a hydrocarbon composition for use in CI engines, said composition comprising a blend of hydrocarbons derived from a LTFT and from a HTFT process, said LTFT derived hydrocarbon being blended with said HTFT derived hydrocarbon in a volumetric ratio of from 1:20 to 20:1. The invention further provides a process for the production of the hydrocarbon composition and a the fuel composition including, in addition to the hydrocarbon composition, one or more component selected from the group including a crude oil derived diesel fuel, a crude oil derived naphtha, a lubricant or light cycle oil (LCO).
Abstract:
The process described by this invention involves the hydroconversion of vegetable oils appropriately selected for the production of N-paraffins, through hydrotreatment of a stream of vegetable hydrocarbon oils in and/or natural fats that may be used in a pure state or in a mixture with mineral hydrocarbon oil. This mixture flow is submitted to the process of hydrotreatment, obtaining as a result, a product flow with an elevated content of N-paraffins in the range of C10-C-13. This process provides an alternative to the usual process that uses a mineral hydrocarbon oil load (petroleum kerosene of paraffin base) to produce C10-C13 N-paraffins that are raw materials for the production of detergents (LAB), being, therefore, especially advantageous for use in situations where kerosene is a limiting factor for producing N-paraffins, resulting in a product of good quality with a reasonable gain in the production of N-paraffins.
