发明名称 METHOD FOR THE REMOVAL OF NON-METAL AND METALLOID HYDRIDES
摘要 A method is provided for the removal of metalloid and non-metal hydrides from gas or liquid media. The improvement is provided by the use of a hightemperature carbonaceous char derived from a carbonaceous feedstock which has been exposed to nitrogen containing compounds at temperatures above 700 ~C. In the preferred embodiment of the method, the high-temperature carbonaceous char is prepared by carbonizing and oxidizing a bituminous coal at temperatures less than 700 ~C followed by exposure to urea, ammonia, or nitrogen-containing compound as the temperature is raised to above 700 ~C.
