标 题 :Transition metallohalopolymers
发明人：KOLOSKI TIMOTHY S; VARGO TERRENCE G

摘要:Novel metallohalopolymers comprising an oxyhalopolymer and a transition metal covalently bonded to an oxygen site on the oxyhalopolymer possess desirable properties of inertness, stability, hydrophobicity and high electronegativity like fluoropolymers such as PTFE. The metallohalopolymers also possess unusual superacidic properties making oxygen-containing sites on the polymeric backbone highly nucleophilic and reactive with transition metals for synthesis of stable metallized polymers without requiring exposure to destructive calcining temperatures or intermediate chelating organosilane linking agents. The transition metals can be covalently bonded directly to the polymeric support to form metallohalopolymers for use as catalysts in the synthesis of chemicals, biocides and useful articles of manufacture, such as filtration devices containing the biocidally active metallohalopolymers.

摘要:The present invention provides a process for decreasing or eliminating unwanted hydrocarbon and oxygenate products caused by FTS reactions in a syngas treatment unit by utilizing heat exchangers and optionally associated pipes that are substantially fabricated of a metal material selected from the group consisting of iron, nickel, cobalt, carbon steel or stainless steel and having deposited on the metal surfaces that will come in contact with the coldbox overhead gas stream an inert coating selected from the group consisting of silicon based materials, zinc based materials, tin based materials, chromium based materials, polymers, ceramics and mixtures thereof for heating up gas streams having a mixture of hydrogen and carbon monoxide and obtained from a front end purification unit/cold box unit.
