New Reaction Technologies

As stated earlier, an increased interest is currently being concentrated on smaller-scale hydrogen production for fuel cell applications ranging from industrial to residential and mobile implementations. An especially important emphasis has been placed on the design of on-board fuel processors capable of generating the hydrogen necessary to power vehicles. Another application of the mobile fuel processor under development is the portable processor/fuel cell system capable of powering electronic devices with liquid hydrocarbon fuels, as replacement for batteries.24 26

As previously indicated, a sample of over two kilograms in size of perfluoro [15]crown-5 has been made by new technology at Exfluor Research Corporation in Austin, Texas (27J. With new reaction technology the yields are on this substance are in the high ninety percent range and large quantities are possible. This opens the possibility of preparing any of the materials in this manuscript on a commercial scale. 

UK [15] and Japan [16]. Tert-butanol/iso-buntene/IUO was proposed for lower quality waste thermal energy recovery [17] at less than 60 °C as an organic reaction type. This history says that development of new reaction and material technologies creates new possibility of thermochemical energy technologies. 

It is envisioned that this new LAB technology would be most readily applicable industrially as a retrofit to existing LAB commercial units, possibly as a slip-stream reactor.19,20 The manufacturer would then have the flexibility to tailor the 2-phenyl content of their LAB and LAS products according to the customer s specific needs. Alternative solid acid reactor configurations have been presented at an earlier Organic Reactions Catalysis Meeting.21... 

In general, the area of C02 utilisation for carbon storage is relatively new and less well known compared to other storage approaches, such as geologic storage. Thus, more exploratory technological investigations are needed to discover new applications and new reactions. 

Whereas in the last decade microwave irradiation was mainly applied to accelerate and optimize well-known and established reactions, current trends are indicative of the future use of microwave technology for the development of completely new reaction pathways in organic synthesis. Limited by vessel and cavity size, microwave-assisted synthesis has hitherto been focused predominantly on reaction optimiza-... 

Modeling has become an important tool in developing new battery technology as well as for improving the performance of existing commercial systems. Models based on engineering principles of current distribution and fundamental electrochemical reaction parameters can predict the behavior of porous... 

Another example is butene dimerization catalyzed by nickel complexes in acidic chloroaluminates 14). This reaction has been performed on a continuous basis on the pilot scale by IFF (Difasol process). Relative to the industrial process involving homogeneous catalysis (Dimersol process), the overall yield in dimers is increased. Similarly, selective hydrogenation of diene can be performed in ionic liquids, because the solubility of dienes is higher than that of monoene, which is higher than that of paraffins. In the case of the Difasol process, a reduction of the volume of the reaction section by a factor of up to 40 can be achieved. This new Difasol technology enables lower dimer (e.g., octenes) production costs 14).
