High purity microporous vanadosilicate (EVS-10/AM-6) has been hydrothermally synthesized by a simple template-free, reducing agent-free method in the absence of titanosilicate ETS-10 seeds. Direct comparison between EVS-10 and ETS-10 showed successful isomorphous substitution of titanium with...
Athabasca oil sands contain 8 to 14% bitumen and are recovered using surface mining or steam assisted gravity drainage (SAGD). During primary upgrading of bitumen, the vacuum residuum from the distillation column is sent to the solvent de-asphalting unit where a paraffinic solvent is used to...
Impact of petroleum coke characteristics on the adsorption of the organic fractions from oil sands process-affected water
Most crude oils contain traces of vanadyl porphyrins within their asphaltene fraction. Although these metals are only present in trace quantities, they have a significant detrimental impact on crude oil processing units; therefore, their selective removal is highly desirable. The current work...
The most prevalent oxidation states of vanadium in nature are V(IV) and V(V). Toxicity of vanadium increases with increasing oxidation state. A high-performance-liquid-chromatography inductively-coupled-plasma mass-spectrometry method was optimized for the speciation of V(IV) and V(V). It was...
