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

Based on the thermodynamic calculations of the equilibrium composition of the gasification products of shale from the Kendyrlyk deposit (Republic of Kazakhstan) (air blast coefficient α = 0.3; pressure, 0.1 MPa) with consideration for the chemical composition of the ash of mineral components (SiO 2 , Al 2 O 3 , Fe 2 O 3 , CaO, MgO, K 2 O, and Na 2 O) and the concentrations of trace elements (Cu, Sr, Zn, Cr, Ti, Mn, and Ni) in it, the constituents of a gas phase (the most probable of 500 substances) were determined depending on the process temperature. The equilibrium compositions of gas and condensed phases at a temperature of 1185.65 K were calculated using the HSC Chemistry software.
