标题:Vapor phase cracking of dicyclopentadiene and synthesis of 2,3-dihydroxycyclopentadiene and cyclopentene

摘要:Improved process for vapor phase cracking of dicyclopentadiene and synthesis of 2,3-dihydrodicyclopentadiene therefrom. Initially, a feedstock consisting essentially of dicyclopentadiene and cyclopentene is subjected to thermocracking in the vapor phase, resulting in the conversion of dicyclopentadiene to monomeric cyclopentadiene. The presence of cyclopentene in the feed stock is believed to minimize coke formation on the interior walls of the cracking chamber. Subsequent selective catalytic hydrogenation of the resulting mixture converts substantially all of the monomeric cyclopentadiene to cyclopentene. The cyclopentene, prepared in the above manner, can be combined with additional quantitie;s of dicyclopentadiene and the resultant mixture subjected to dimerization in the liquid phase at elevated temperatures, thereby forming the monomer, 2,3-dihydrodicyclopentadiene.

标题:Method of synthesizing hydrocarbons and alcohols

权利人:UNIV SOUTH CAROLINA
摘要:Improved economies are achieved in the synthesis of hydrocarbons and alcohols from hydrogen/carbon monoxide mixtures by adding steam to a hydrogen-lean synthesis gas derived, e.g., from the gasification of a liquid or solid fossil fuel and carrying out the synthesis in the presence of a catalyst comprising hydrided titanium supported on a metal or inter-metallic compound capable of forming an unstable hydride.

摘要:Filled carbon nanotubes (CNTs) and methods of synthesizing the same are provided. An in situ chemical vapor deposition technique can be used to synthesize CNTs filled with metal sulfide nanowires. The CNTs can be completely and continuously filled with the metal sulfide fillers up to several micrometers in length. The filled CNTs can be easily collected from the substrates used for synthesis using a simple ultrasonication method.
