Improved Configuration and Process for Shift Conversion


The inventors discovered that a significant portion of steam in hydrogen production from syngas (and other gases with relatively high CO to H2 ratio) is utilized for temperature control in the shift reactors. Therefore, it is contemplated that the overall steam demand can be significantly lowered by splitting the feed stream in a first and […]

Polycarbosilane Adhesion Promoters for Low Dielectric Constant Polymetric Materials


The adhesion of low k poly(arylene ether) dielectric coating compositions is effectively enhanced by a polycarbosilane promoter additive or primer. A coating composition is prepared by (a) providing a poly(arylene ether) composition; and (b) adding to said composition a small effective adhesion promoting amount of certain polycarbosilanes. The adhesion enhanced coating compositions are cured by […]
