The main obstacle to the widespread use of hydrothermal liquefaction (HTL) for waste and wet biomass recycling is formation a significant amount highly polluted wastewaters. This paper presents an analysis chemical composition toxicity aqueous phase from HTL (HTL-AP) primary secondary sludge. It was shown that HTL-AP has high level organic pollution (total carbon (TOC) = 4.2–9.6 g/dm3, oxygen d...
The effective parameters that influence in situ cast ferroTic composites were investigated. Centrifugal casting of specimens was carried out using ceramic & metallic molds. OM, SEM and XRD techniques were used to examine the existence of flows in the specimens. Results show that the control of chemical composition, processing, cooling rate and heat treatment has a promising effect on the qual...
Compositions of Al2O3+Si, SiO2+Al and Al+Si systems were prepared to study the effect of reaction bonding process on the mullite formation. The composition of each system was adopted according to mullite stoichiometery and sintered in 700-1600°C range. Results showed that the formation of reaction bonded mullite starting from Al2O3+Si mixtures, proceeded in two partially overlapping steps, the ...
Abstract: Thermodynamic computational packages MTDATA and FactSage have been used to carry out calculations on the variation with temperature of the phases precipitated on cooling in both oxidising and reducing conditions of a typical ladle slag composition, in the temperature range 1700 - 900°C. The current coverage of the databases associated with the computational packages is discussed i...
