Abstract:
PROCESS FOR THE MANUFACTURE OF FURAN COMPOUNDS The present invention relates to a process for the manufacture of furan compounds by the direct oxidation of conjugated diolefins with air or oxygen in the liquid phase in the presence of a transition metal catalyst system.
Abstract:
Cyclic carbonates are manufactured from oxiranes, such as methyl oxirane (propylene oxide), and heterocumulenes, such as carbon dioxide, in the presence of a catalytic system. The catalytic system is a combination of a Group IVB or VB transition metal complex and a Lewis base, such as a bromide ion.
Abstract:
HYDROTREATING HYDROCARBON FEEDS USING AMPHORA SHAPED CATALYSTS Catalysts having a substantially spherical shape, a void center and a hole in the external surface communicating to the void center, have been found to give superior results in known hydrotreating reactions where sulfur, nitrogen and/or oxygen is removed from a hydrocarbon feed stock.
