  • Patent number: 3979366
    Abstract: An improved process for the suspension polymerization of vinyl chloride homopolymers is accomplished by the addition of small amount of chain extending agent to the polymerization formula allowing the polymerization to be run at a higher temperature thus making better use of the reactor's heat removal capability. More efficient use of initiator is also accomplished while producing polyvinyl chloride having the desired molecular weight dependent physical properties. The process also allows a faster rate of polymerization.

  • Patent number: 3979466
    Abstract: A process for producing higher molecular weight alcohols by forming a reaction mixture of at least one lower molecular weight primary or secondary alkanol having a methylene group adjacent the hydroxylated carbon atom, an alkali catalyst and a palladium (II) compound, said palladium compound being mixed with the alkanol prior to dissolution of the alkali catalyst therein, and heating the reaction mixture to effect condensation of the alkanol while simultaneously removing water as it forms.

  • Patent number: 3977843
    Abstract: An improved method for removing sulfur compounds during coal gas methanation comprising removing essentially all carbon dioxide and hydrogen sulfide from synthesis gas, then adding carbon dioxide containing lower levels of sulfur back to the gas stream before feeding the mixture to a desulfurization reactor. Carbon dioxide, at levels above about 12 percent, will prevent high temperature methanation runaways in the hydrodesulfurization reactor, where a stream consisting essentially of hydrogen sulfide and methanation materials is produced, the lower level of hydrogen sulfide produced being removed by conventional methods before proceeding to methanation units. The carbon dioxide can be supplied either from an outside source or can be obtained from the synthetic natural gas after methanation.

  • Patent number: 3941820
    Abstract: Predominantly aliphatic hydrocarbon materials may be obtained from carbonaceous solids by a sequence of steps comprising gasifying the carbonaceous solids, combining the gasification product stream with an internal recycle stream, separating certain impurities from the combined stream followed by cooling to liquefy and separate the hydrocarbon materials while directly reacting the remaining carbon monoxide and hydrogen in the presence of a catalyst to produce the internal recycle stream.
