- GAS-TO-LIQUID REACTOR AND METHOD OF USING
-
A device and a process to propagate molecular growth of hydrocarbons, either straight or branched chain structures, that naturally occur in the gas phase to a molecular size sufficient to shift the natural occurring phase to a liquid or solid state is provided. According to one embodiment, the device includes a grounded reactor vessel having a gas inlet, a liquid outlet, and an electrode within the vessel; a power supply coupled to the electrode for creating an elecirostatic field within the vessel for converting the gas to a liquid and or solid state.

- Paraffin alkylation
-
A liquid acid process is disclosed in which a hydrocarbon component containing an olefin, an olefin precursor or mixture and an isoalkane and a liquid acid catalyst is fed to a downflow reaction zone containing a disperser, under conditions to induce pulse flow at or near the outlet to react the isoalkane and olefin to produce a reaction product and feeding the reaction product to a vaporization zone containing a disperser under conditions to induce pulse flow at or near the outlet of the vaporization zone. A pressure drop across the disperser in the vaporization zone causes partial vaporization of the hydrocarbon which quench es the heat reaction and cooling the unvaporized portion of said reaction product, which is recovered and allowed to separate into an acid phase and hydrocarbon phase containing the alkylate. The acid catalyst and hydrocarbons may be fractally fed to the reaction zone.

- Mecanisme de l'alkylation de l'isobutane par le propene sur zeolithe. I. Etudes preliminaires de la selectivite de la reaction
-
Alkylation of isobutane by propylene has been studied at 70 and 80 deg C and 10 atm. of pressure over a cerium exchanged Y zeolite.Under these conditions large amounts of olefin are converted into adsorbed residues and C5-C9 isoalkanes (alkylate) are formed.Maximum alkylate yields are observed after 12 hours and become negligible after 24 hours.The main products result from alkylation, dimerization, self-alkylation and cracking reactions followed by hydride transfer.Catalyst poisonning is explained by the decrease of the zeolite cracking activity and dehydrogenation of the adsorbed species.
