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 work aims to create a formalized scheme of the hydrocarbons transformation in the catalytic cracking with the participation of high-molecular hydrocarbons of vacuum distillate in order to predict the gasoline group composition and the gases individual composition. Thermodynamic parameters of the most probable reactions of cracking gases formation under technological conditions of the process using the reference data and Density Functional Theory are determined; the features of the mechanism of hydrocarbon transformations on acid catalysts determining the high content of isoalkanes, alkenes, aromatic hydrocarbons in cracking products are taken into account.
