Evaluation of thermodynamic data and phase equilibria in the system Ca–Cr–Cu–Fe–Mg–Mn–S part I: Binary and quasi-binary subsystems

Internal differentiation and volatile budget of Mercury inferred from the partitioning of heat-producing elements at highly reduced conditions

“…1d), the only sulfide phase is pure MgS, which occurred as 30-40 μm in width blobs with smooth and irregular contours. MgS was likely a solid phase, because the experiment was performed well below (1520 • C) their very high melting temperature (~2200 • C, Jantzen et al, 2017). In several experiments, the silicate glass contains micro-globules (<1 μm) of metal comparable to those described in previous studies (Fig.…”

Gibbs Energy Modeling of the Cu-S Liquid Phase: Completion of the Thermodynamic Calculation of the Cu-S System

“…Within a critical assessment and thermodynamic modeling of the Cu-O and Cu-O-S systems, Shishin and Decterov [11] described the Gibbs energy of the Cu-S liquid solution phase on the basis of the optimization by Waldner and Pelton. [9] Jantzen et al [12] took copper sulfide Cu 2 S as the liquid solution constituent into account for their calculation of the Cu-S phase diagram.…”

The bioliq® Entrained‐Flow Gasifier – A Model for the German Energiewende

“…Accompanying research into the bioliq entrained-flow gasifier is being carried out within the Energy Efficiency, Materials, and Resources (EMR) energy research program of the HGF and the Helmholtz Virtual Institute Gasification Technology (HVIGas-Tech) joint research cooperation [9]. This is where the following subprocesses are being studied: (i) atomization of high-viscosity suspensions under pressure [10], (ii) heterogeneous reaction kinetics of coke particles [11], (iii) heat transport of particles and gas at high pressure [12], and (iv) slag production and factors influencing slag flow [13]. Moreover, measuring techniques are being developed for application in high-pressure Operation of the bioliq pilot-scale gasifier, on the one hand, serves to accumulate experience in plant operation with different feedstocks and to optimize the operating process and plant technology and, on the other, to supply process data both for modeling the subprocesses in the gasifier and for validating the simulation tool.…”
