An Investigation of the destruction of ion exchange resins
Ion exchange resins are used for many purposes in various areas of science and commerce. One example is the use of cation exchange resins in the nuclear industry for the clean up of radioactively contaminated water (for example the removal of 137Cs). However, during removal of radionuclides, the …

The catalytic conversion of low chain length hydrocarbons to liquid fuels using ion exchange resin
The use of ion exchange resins in the polymerization of a c 4 -mixture to liquid fuels has shown that the catalyst is highly active, deactivates at a slow rate and selectively produces mainly dimers. Macropore diffusion resistance strongly influences the overall rate of the reaction. An increase in …
