Data confidence 70 medium

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

Abstract Experimental results on the kinetics of hydrogenation of a wide fraction of coal tar (bp 230–300°C) in the presence of a Fe3O4 nanocatalyst are presented. The rate constants, overall rate constants, and activation energies were calculated. It was established that the conversion of preasphaltenes into asphaltenes is the rate-limiting stage of the conversion of a wide fraction (230–300°C) of coal tar into reaction products. The process of converting the wide fraction (230–300°C) into products takes place in the kinetic region of a heterogeneous process.
