LTFT syncrude has significant chemicals potential in the field of linear paraffins and waxes, with some potential for olefin and oxygenate chemicals too. It is also well suited for the production of lubrication oils by catalytic dewaxing. 

Catalytic Dewaxing Also called CDW. A hydiocracking process for removing waxes (linear aliphatic hydrocarbons) from petroleum streams by converting them to lower molecular weight hydrocarbons. The catalyst is a synthetic mordenite. Developed by BP two units were operating in 1988. 

Iso-CDW [Isomerization and catalytic dewaxing] A general term for dewaxing processes which include these two processes. Exemplified by Isodewaxing, MSDW. 

Isodewaxing A catalytic dewaxing process developed by Chevron Research Technology. It incorporates catalysts that achieve both wax isomerization and shape-selective cracking. 

MSDW [Mobil selective dewaxing] A catalytic dewaxing process which uses a catalyst containing a shape-selective molecular sieve and a noble metal. 

Catalytic dewaxing, in which straight-chain paraffin hydrocarbons are selectively cracked on zeolite-type catalysts, and the lower-boiling reaction products are separated from the dewaxed lubricating oil by fractionation.

The state of the art, today, is based on an all catalytic lube plant, which does not rely on solvent processing. An example of such a plant is Mobil s Jurong plant located in Singapore (11). The configuration of the plant relies on the use of a lube hydrocracker, coupled with a selective catalytic dewaxing unit (Fig. 8.2).

Catalyst performance is determinedby activity, selectivity andstability. Whereas activity is indispensable, selectivity is often of prime importance (e.g. lube base oil yield in catalytic dewaxing), particularly if an improved selectivity can break a bottleneck in a unit (e.g. by lower gas makes which break up the gas train bottleneck a in a hydrocracking unit). Catalyst life is determined both by the start of run activity and deactivation rate. With high activity catalysts in low severity duty (e.g. naphtha hydrotreating), catalyst life can be very long (e.g. 5-10 years), and in some cases the...
