Selective production and reaction of p-Disubstituted aromatics over zeolite ZSM-48

Abstract: Para-Disubstituted aromatics are produced in the presence of a catalyst comprising zeolite ZSM-48 Selective cracking of para-isomers may also be accomplished to produce mixtures rich in meta-isomers

Use of dilute aqueous solutions of alkali polysulfides to remove trace amounts of mercury from liquid hydrocarbons

Abstract: Disclosed is a method of removing mercury from contaminated liquid hydrocarbons (natural gas condensate) by contacting them with a dilute aqueous solution of alkali metal sulfide salt and recovering the treated liquid hydrocarbon. The addition of alkali metal hydroxide enhances the phase separation of hydrocarbon and aqueous solution.

Valveless shut-off and transfer device

Abstract: A valveless gas shut-off and transfer device has a looped conduit with a solder-like material in the loop. This eutectic material solidifies below its critical temperature to block the conduit and is liquefied above its critical temperature to allow passage of gas through the conduit. Baffles on the outlet retain the liquefied solder when gas is passing through the device. The liquid solder flows back to the loop when pressures at the inlet and outlet are equalized. When the solder solidifies, the device is again blocked.

Thermoplastic bag, bag pack and method of making the same

Abstract: A thermoplastic bag structure comprising a front and rear bag wall, a bottom and an open mouth top portion, said open mouth portion being characterized by having two pairs of single film handle loops each of which are located at opposite ends of said open mouth portion, the handles of each pair being side-by-side and each handle is an integral single film loop extension of said front and rear bag walls The bag structures can be unitized by providing a detachable tab at the bag mouth opening and unitizing the bag structures through this tab The method of forming said bags involves providing an end sealed collapsed thermoplastic film tube and removing plastic to form a bag mouth opening and handles at one end thereof The resulting bag is an ungussetted bag which can be unitized into a pack by providing a detachable, unitizing tab at the bag mouth opening

Stability of Aqueous Wetting Films in Athabasca Tar Sands

Abstract: The existence of thin films of water that completely wet the sand grains has long been regarded as an important feature of the Athabasca oil sands deposit Direct microscopic evidence, however, cannot be relied on to establish whether such films are present The existence and stability of such films, therefore, must be inferred from the relevant surface chemical forces for the oil/brine/rock system A detailed analysis of these forces shows that the stability of these thin wetting films is critically dependent on whether the zeta potentials (and charge densities) for the two electrical double layers bounding the film are of like sign The zeta potential and charge density for the rock/brine interface will in almost all cases be negative in sign Therefore, a requirement for the stability of a wetting film will be that these quantities are also negative at the brine/oil interface New measurements of the electrophoretic mobility of small particles of Athabasca bitumen suspended in an aqueous phase are reported These data show that the zeta potential at the bitumen/water interface is strongly negative Consequently, these results support the hypothesis that wetting films will be stable in this instance
