The other competing bulk propylene processes include the Mitsui Hypol process and the various offshoots of the El Paso (or Rexene) process. In 2005, ExxonMobil announced that they were licensing a propylene bulk process based on the loop reactor. The front end of the ExxonMobil process is similar to the Spheripol process with a single or double loop, but a fluidized-bed gas-phase reactor is used for impact copolymer instead of the stirred-bed gas-phase reactor in a typical Spheripol process.

The new commercially available technologies concern the removal of sulfur with a minimum lost of octane rating. SCANfming and Prime G+ are the process technologies licensed by ExxonMobil and IFP, respectively. In SCANfining (Fig. 4), the complete naphtha (full range naphtha) is treated, with a proprietary catalyst. 

Some other processes are based on a severe hydrotreatment followed by a stage for octane recovery. Octgain from ExxonMobil [57] and ISAL from UOP-Intevep [58], Deep desulfurization is achieved by an increase in severity, causing lost in octane by olefins saturation. In the first case, in a second reactor octane number is recovered by a combination of cracking and isomerization reactions. In the latter case, the catalyst employed during desulfurization possess isomerization capabilities inhibiting an excessive octane lost. Other mentioned functionalities of the catalyst include dealkylation and conversion.

Mountain states), Chevron (Standard of California), Exxon (from Standard of New Jersey), Sohio (Standard of Ohio), Marathon (covering western Ohio and other parts of Ohio not covered by Sohio), and Mobil (Standard of New York). These companies, derived from the Standard Oil Co., formed an original oil industry map in US, but that map no longer exist, rather the merging and acquisition processes reduced all them into four of the seven majors (ExxonMobil, ChevronTexaco, ConocoPhillips, and BP America).

The catalysts for xylene isomerization with EB dealkylahon are dominated by MFI zeolite. The de-ethylation reaction is particularly facile over this zeolite. There have been several generations of catalyst technology developed by Mobil, now ExxonMobil [84]. The features in their patents include selectivation and two-catalyst systems in which the catalysts have been optimized separately for deethylation of EB and xylene isomerization [85-87]. The crystallite size used for de-ethylation is significantly larger than in the second catalyst used for xylene isomerization. Advanced MHAI is one example. The Isolene process is offered by Toray and their catalyst also appears to be MFI zeoUte-based, though some patents claim the use of mordenite [88, 89]. The metal function favored in their patents appears to be rhenium [90]. Bimetallic platinum catalysts have also been claimed on a variety of ZSM-type zeolites [91]. There are also EB dealkylation catalysts for the UOP Isomar process [92]. The zeolite claimed in UOP patents is MFI in combination with aluminophosphate binder [93]. 

The catalyst used in the TransPlus process jointly developed by ExxonMobil and CPC uses a proprietary zeolite [76]. From the literature, the SK Energy ATA-11 catalyst appears to be based on either mordenite or beta zeolite using attenuated noble metals. The UOP TAC9 process was developed by UOP and Toray and is licensed by UOP (outside Japan and Korea). The UOP Tatoray process is based on a bi-functional catalyst with long catalyst life, minimal ring loss and hydrogen consumption in comparison with noble metal catalyst systems.

The highly esteemed management professor Peter Drucker once said, Success is more likely to result from the systematic pursuit of opportunities than from a flash of genius. I will discuss the systematic pursuit of innovation used at ExxonMobil Chemical Company to increase the yield from basic science to commercialization. Although innovation is thought of as an inherently fuzzy process, my role in the last 5 to 10 years of my 35-year career has been to add a fair amount of structure and discipline to the process of innovation. Some of our best practices will be shared. 

Allen Clamen, ExxonMobil (retired) I agree with Michael that collaboration has many different forms. I am intrigued by the way needs and solutions find each other. I think the challenge we have at the very early stages in the idea management process is to find information within or even outside the organization that could make immature ideas more robust and attractive, which will persuade others that the ideas are worth pursuing.
