Process for the production of phenylalkanes using a hydrocarbon fraction that is obtained from the Fischer-Tropsch process

A process for the production of phenylalkanes comprising a reaction for alkylation of at least one aromatic compound by at least one hydrocarbon fraction that is directly obtained from the Fischer-Tropsch process comprising linear olefins that have 9 to 16 carbon atoms per molecule and oxygenated compounds is described. Said alkylation reaction is carried out in a catalytic reactor that contains at least one reaction zone that comprises at least one acidic solid catalyst, and said hydrocarbon fraction does not undergo any purification treatment prior to its introduction into said reaction zone.

Relationship of structure to properties of some anionic surfactants as collectors in the flotation process. 1. Effect of chain length

The surface and thermodynamic properties of some synthetic surfactants, as well as their efficiency as collectors in the flotation of petroleum coke, are studied. These surfactants are monoisomeric alkylbenzenesulfonate of different alkyl chains (C12 to C14). The results show that the length of the hydrocarbon chain of these surfactants plays a major role in determining their surface and thermodynamic properties. The values of surface excess concentration (Γmax) and Gibbs energy of micellization (ΔG°mic) are found to increase with increasing number of carbon atoms in the chain while the values of critical micelle concentration (cmc) are decreased. The results indicate, also, that there is a good relationship between effectiveness of adsorption of a surfactant and its efficiency as a collector. A surfactant of higher Γmax produces a concentrate of lower ash content and higher flotation yield. Thus, the surfactant with longer alkyl chain (C14) and highest Γmax value is more selective, as a collector, than others of shorter carbon chain.
