    Abstract: A process for improving the pour point of a feed comprising paraffins containing more than 10 carbon atoms, in which the feed to be treated is brought into contact with a catalyst comprising at least one zeolite with structure type MTT, TON or FER or any possible combination of these three, at least one hydro-dehydrogenating element selected from elements from group VIB and group VIII of the periodic table, at least one deposited promoter element (boron, silicon, phosphorous), optionally at least one group VIIA element, optionally at least one group VIIB element, at a temperature in the range 170° C. to 500° C., a pressure in the range 1 to 250 bars and at an hourly space velocity in the range 0.05 to 100 h−1, in the presence of hydrogen in an amount of 50 to 2000 l/l of feed. The oils obtained have good pour points and high viscosity indices (VI). The process is also applicable to gas oils, and other feeds requiring a reduction in pour point. The invention also relates to a catalyst containing silicon and to its use for converting hydrocarbon-containing feeds.

    Abstract: The fractional distillation performed as part of the isomerization of C5-C6 paraffins is heat integrated. A portion of a sidedraw recycle stream is employed to cool the feed to a deisohexanizer column and then returned to a lower portion of the column. This reduces the reflux demand of the column and the operating cost of the process.

    Abstract: Construction and operational costs of simulated moving bed adsorptive separation process units are reduced by recovering desorbent from both the extract and raffinate streams of the process in a single integrated fraction column. Both streams are fractionated to recover desorbent, which is removed at one end of a dividing wall column, while separate extract and raffinate products are removed from the other end of the column. A specific embodiment includes the use of the integrated fractionation column in an isomerization application.

    Abstract: Construction and operational costs of recovering the high-octane components of an isomerization raffinate product of a simulated moving bed adsorptive separation process units are reduced by employing a dividing wall column to perform the separation. The raffinate product stream is passed into the column at an intermediate point on the first side of the dividing wall, with the column delivering the low-octane raffinate components as a sidedraw from the opposite side of the dividing wall. A stream of higher octane components are removed both as an overhead stream and a bottoms stream. The sidedraw may be recycled to the isomerization zone.

    Abstract: A slurry Fischer-Tropsch hydrocarbon synthesis process for synthesizing liquid hydrocarbons from synthesis gas in a hydrocarbon synthesis reactor also hydroisomerizes the synthesized hydrocarbon liquid, which comprises the slurry liquid, in one or more downcomer reactors immersed in the slurry body in the synthesis reactor. A monolithic catalyst is preferably used for the hydroisomerization, and slurry circulation down through the downcomer reactors from the surrounding slurry body, is achieved at least in part by density-difference driven hydraulics created by removing gas bubbles from the slurry passed into the downcomers. Preferably, catalyst particles are also removed before the slurry contacts the catalyst. Hydroisomerization occurs while the synthesis reactor is producing hydrocarbons, without interfering with the hydrocarbon synthesis reaction.
