Selectivity support

The integrity of pipelines depends upon conect design, including materials selection, support and protection from mechanical damage. Depending upon tlie gas, routine inspection and maintenance may be supplemented by the provision of gas detection and alarm systems. Other considerations are exemplified by the safety-related controls on the transportation of domestic gas via pipeline systems summarized in Table 15.17.

All of these problems are related to the performances of the catalysts used in coal liquefaction. Very active, durable, recoverable, and regenerable catalysts are most wanted in the primary liquefaction stage, where catalyst poisons from asphaltenes and minerals are most severe. Multifunctional catalysts should be designed by selecting supports with specific functions, such as strong but favorable interactions with catalytic species, resistance to poisons, and improved properties to allow easy recovery, while maintaining high activity. 

An evaluation of some selected supports (22) as to splitting of gas oil at atmospheric pressure gave results shown in a qualitative way in Table IX. The supports are arranged in order of increasing splitting activity. 

The racemic inhibitor thiorphan 46) 25 inhibits enkephalinase and selectively supports the analgesic effect of enkephalins. 

There is no doubt that the initial selectivity is governed by the characteristics of the oxygen at the surface. The subsequent reactions also influence the overall selectivity support acid sites catalyze the isomerization of EO giving acetaldehyde, which is very reactive towards complete combustion. The beneficial influence of alkali promoters is due to the poisoning of the acid sites at the catalyst support.
