How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Isomerization of n-hexane was carried out in the presence of hydrogen over Pt- and Pt-Re- supported on the matrix of complex composition (natural klinoptilolite clay, alumina-silica gel) and alumina. Pt- catalysts on the compost containing clinoptilolite clay, alumina-silica-gel, decationed and exchanged zeolite (HCeY) showed the isomers selectivity at a wide range of temperature interval (350-450 oC ). It was shown that the high activity and selectivity of studied catalysts correlated with the concentration of strong and medium acid sites on the surface of catalysts.
