Study of effect of parameters on separation of cresol isomers
2017年10月1日 · In the current work, a detailed experimental study has been carried out to establish the feasibility of stripping crystallization process for separating out para - and meta - cresols from their mixture. Gas Chromatography has been used to determine the purity of the distinct cresols obtained from the experiments.
CoAPO systems. Recycling of the catalysts at sufficiently low cobalt over p-cresol ratios indicates that the CoAPO catalysts are not stable under reaction conditions; cobalt is released from the partially dissolved CoAPO molecular sieve. The observed catalytic activity mainly stems from this dissolved cobalt.
