However, in our experiments, the solution after photodegradation is colorless, and no clear absorption peaks corresponding to aromatic intermediates and ring cleavage products are detected in the spectra, as shown in Figure 9, which indicates that there is little photodegradation intermediates produced in the photodegradation of phenol process
and the good photocatalytic performance of our samples.
The plant is to utilise UOP C3 Oleflex process technology to convert propane to propylene, a substance used in the production of materials including films and packaging, and the UOP Q-Max and UOP Phenol process
technologies will be integrated to convert cumene to phenol, a building block for materials like plastic and nylon.
The calculated [R.sub.L] values at different initial phenol concentration, shown in Table 3, were all in the range of 0-1, which confirms the favourable adsorption of the phenol process
in the studied concentration range.
