n-Paraffin Production

The Molex process offers you an opportunity to upgrade straight-run kerosene to normal paraffins (n-paraffins). The Molex process is a commercially proven, cost-effective process that efficiently separates n-paraffins from the branched and cyclic analogs.

Normal paraffins are used primarily as a raw material to produce linear alkylbenzene, which is then used to produce surfactants. The first Molex unit began commercial operation in 1968. Today, more than 2.5 MM metric tons of n-paraffins are produced from Molex units around the world.

The Molex process uses the Sorbex simulated-moving-bed technique to recover high-purity n-paraffins by continuous adsorptive separation. This technique is similar in concept to liquid chromatography, but done on a very large commercial scale.

In an n-paraffin complex, the feed to the Molex unit is generally hydrotreated in a Unionfining unit which, along with UOP’s hydrotreating catalyst, ensures trouble-free production of top quality n-paraffins.

ADS-34 adsorbent is a high-performance molecular sieve zeolitic adsorbent which enables a Molex unit to produce 99 wt% pure n-paraffin products at more than 97 wt% recovery per pass.
