摘要:
A process for removing Hg 2+ ions from a liquid stream is disclosed. The process involves contacting the liquid stream with specified UOP Zeolitic Materials. These molecular sieves are particularly effective in removing Hg 2+ ions from aqueous streams even in the presence of Mg 2+ and Ca 2+ ions. The effective molecular sieves have an intermediate range of Si/Al ratios between 2 and 20 and preferably between 3 and 10.
摘要:
A new family of crystalline microporous metallophosphates designated AlPO-57 has been synthesized. These metallophosphates are represented by the empirical formula R + r M m n+ EP x Si y O z where R is an organoammonium cation such as the DEDMA + , M is a divalent framework metal such as an alkaline earth or transition metal, and E is a framework element such as aluminum or gallium. The microporous AlPO-57 compositions are characterized by a new unique ABC-6 net structure and have catalytic properties for carrying out various hydrocarbon conversion processes and separation properties for separating at least one component.

A new family of crystalline microporous metallophosphates designated MAPSO-64 has been synthesized. These metallophosphates are represented by the empirical formula R+rMmn+EPxSiyOz where R is an organoammonium cation such as ETMA+ or DEDMA+, M is a divalent metal such as an alkaline earth or transition metal, and E is a framework element such as aluminum or gallium. The microporous MAPSO-64 compositions BPH topology and have catalytic properties for carrying out various hydrocarbon conversion processes and separation properties for separating at least one component.
摘要:
A new family of crystalline microporous metallophosphates designated AlPO-67 has been synthesized. These metallophosphates are represented by the empirical formula R+ rMm 2+EPxSiyOz where R is an organoammonium cation such as the ETMA+ or DEDMA+, M is a framework metal alkaline earth or transition metal of valence 2+, and E is a trivalent framework element such as aluminum or gallium. The AlPO-67 compositions exhibit the LEV framework topology and have catalytic properties for carrying out various hydrocarbon conversion processes and separation properties for separating at least one component. The materials may be used as a catalytic composite for hydrocarbon conversions or may be used to separate at least one component from a mixture.
