An oxadiazole dye for use as an organic photosensitizer. The oxadiazole dye comprising donor-&#x3c0;-spacer-acceptor type portions in which at least one of an oxadiazole isomer acts as a &#x3c0;-conjugated bridge (spacer), a biphenyl unit acts as an electron-donating unit, a carboxyl group act as an electron acceptor group, and a cyano group acts as an anchor group. An optional thiophene group acts as part of the &#x3c0;-conjugated bridge (spacer). The dye for use as organic photosensitizers in a dye-sensitized solar cell and in photodynamic therapies. Computational DFT and time dependent DFT (TD-DFT) modeling techniques showing Light Harvesting Efficiency (LHE), Free Energy for Electron Injection (&#x394;G), Excitation Energies, and Frontier Molecular Orbitals (FMOs) indicate that the series of dye comprise a more negative &#x394;Gand a higher LHE value; resulting in a higher incident photon to current efficiency (IPCE).

A catalyst system and a process for methanol to light olefin conversion with enhanced selectivity towards propylene. The catalyst system comprises a honeycomb monolith catalyst support coated with aluminosilicate nanozeolite catalysts on the edges and inside the channels of the support structure. The aluminosilicate nanozeolite catalysts have not been pre-modified with a promoter metal. The catalyst system gives higher hydrothermal stability to the catalyst compared to randomly packed pellet catalysts and allows methanol to be converted to predominantly propylene at a low temperature, with decreased selectivity towards C, higher olefins and paraffinic hydrocarbons.

Method for forming light olefins from methanol

A convectively heated steam/methane reformer having a shell and tube reforming reactor for hydrogen production. A reactor core containing the reactants is convectively heated by hot air flowing through the shell or annulus of the reactor. Heated air is supplied to the reactor through several fluid inlets on the shell side of the reformer.
