13. A process according to claim 7 wherein said crackable high boiling compounds are removed from said second vaporisation stage by stripping in the presence of an inert gas. Description: The present invention relates to the production of phenol and in particular to a process for recovering phen...
phase-diagram structureseparatric manifoldseparation concept— In the large-scale production of phenol by the cumene method, an important constituent is the separation of multicomponent mixtures containing the target products and various impurities. The potential of distillation processes of a specific ...
A laboratory-packed bed column was used for this study. A glass column of 30 cm high and an internal diameter of 30 mm were used. Figure1gives the schematic diagram of the column adsorption process. The adsorbent was separately packed in the column with glass wool at the bottom of the co...

other cleanup methods. The key players in bioremediation are microorganisms that are existing everywhere and ideally suited to the task of contaminant destruction and the production of extracellular hydrolytic enzymes that allow them to use environmental contaminants to sustain growth and vital processes1,...
Phenolic compounds, including phenol and its derivatives, are widely used as key raw materials in chemical production across various fields integral to human life (He et al., 2023; Kim et al., 2023). However, due to their high toxicity, environmental persistence, and bioaccumulative properties,...
The 95% level of confidence interval was chosen for the uncertainty in figure values for gas production and phenol conversion. The flow diagram of this work was the same as the study done by Abdullah et al. [34] and is shown in Figure 1. As a result of the products variation, the ...
When using adsorption processes instead, the cost of production increases significantly due to the low adsorption capacity exhibited for these kinds of pollutants (in addition to being limited by the range of the pH of industrial effluents) [7,8,9] and low reusability, as the cost of the ...
(5)–(8)) in which the Fe(III) functions as electron acceptor and the •OH2/•O2− species generated in the first step is decisive for the production of 1O2 species. The powerful interaction between Fe3O4 nanoparticles and GO sheets facilitates electron transfer. It was also ...
