Investigators at National Academy of Sciences Detail Findings in Alkanes

May 23, 2014

By a News Reporter-Staff News Editor at Science Letter -- Current study results on Alkanes have been published. According to news reporting originating from Yerevan, Armenia, by NewsRx correspondents, research stated, "The nanopowders of Ni and Co metals and their alloy were prepared by plasma-assisted milling, and the activity of catalysts on their basis was studied in the carbon dioxide reforming of methane (CDRM) at atmospheric pressure. It was found that the catalytic activity of Ni nanopowder rapidly decreased because of the blocking of its surface by coking products."

Our news editors obtained a quote from the research from the National Academy of Sciences, "Co powder exhibited lower but stable activity, which gradually decreased as a result of coking only 300 h after the onset of reaction. A Ni-Co alloy (1: 1, by weight) is an active and selective catalyst for CDRM."

According to the news editors, the research concluded: "Its catalytic activity appeared at 400A degrees C; at 870A degrees C, conversion reached 90% and remained unchanged for 500 h. The initial activity was restored by the regeneration of a catalyst based on the Ni-Co alloy with molecular hydrogen for several hours at 400A degrees C."
