  • Metallocene Polyalpha Olefins (Mpaos) Process Economics Program Report 296
    ` IHS CHEMICAL Metallocene Polyalpha Olefins (mPAOs) Process Economics Program Report 296 December 2016 ihs.com PEP Report 296 Metallocene Polyalpha Olefins (mPAOs) Gajendra Kumar Principal Analyst Tony Pavone Sr. Principal Analyst Downloaded 20 December 2016 10:10 AM UTC by Ellen Blue, IHS INC ([email protected]) IHS Chemical | PEP Report 296 Metallocene Polyalpha Olefins (mPAOs) PEP Report 296 Metallocene Polyalpha Olefins (mPAOs) Gajendra Kumar, Principal Analyst Tony Pavone, Sr. Principal Analyst Abstract Polyalpha olefins (PAOs) represent a family of primarily decene-1 oligomers (mostly trimers) that have found wide use as a fully synthetic lubricant base oil component. PAOs provide superior lubricant properties in viscosity, viscosity index, cold cranking capability, emulsion resistance, lower pour point, lubricity, friction reduction, low volatility in use, higher flash temperature, and thermal and oxidative stability. The downside is lower solvency and biodegradation, poorer seal swell, and higher cost. The American Petroleum Institute (API) designates PAO components as Group-4 fully synthetic basestock. Periodic shortages in decene-1 LAO (linear alpha olefin) feedstock availability have forced PAO producers to occasionally blend C10 with both lighter (C8) and heavier (C12) LAO feedstocks to produce PAO with adequate physical and performance properties. The oligomerization process is not very selective, and produces a reactor product containing LAO dimers, trimers, tetramers, and pentamers, plus unreacted feedstock. While originally developed to produce fully synthetic basestock for conventional motor oil requiring 4 centistoke (cSt) viscosity, additional product grades with different viscosities have been supplemented with newer PAO components of much higher viscosity (100+ cSt) that have found widespread use as blend stock components in heavy duty gear boxes, transfer cases, and transmissions, such as those found in wind turbine generators.

The effect of the synthesis temperature of alumina precursors on the dehydration of 1-octadecanol (C18H38O) was examined based on the textural properties and Lewis acid–base properties of the catalysts. Amorphous alumina synthesized at 325 ◦C showed the highest surface area (233.07 m2/g) and total pore volume (1.237 cm3/g) among the catalysts and the best dehydration results: 93% conversion, 62% selectivity of 1-octadecene (C18H36), and 89% LAO purity. This was attributed to the increased Al/O ratio and atomic concentration of surface O in alumina, which were important factors in the catalytic dehydration of 1-octadecanol through the synergistic catalysis of acid–base pairs. The produced bio-based LAO can be key intermediates for synthesis of oxo alcohols and poly-alpha-olefins, as alternatives to petroleum-based LAO to achieve carbon neutrality in chemical industry.
