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

The effect of the particle size and chemical state of chromium in Cr/SiO 2 catalysts with different chromium contents (2–10%) prepared under different conditions upon the properties in the conversion reaction of liquefied petroleum gas (LPG) in the absence and presence of water vapor was studied. It was shown that the degree of conversion of LPG decreases in the presence of water vapor and the selectivity for C 2 –C 4 olefins increases over the Cr/SiO 2 catalysts with a chromium content of 5–7%.
