But the below definition of the mass fraction is also applicable to the other types. In chemistry, most mixtures are solutions, homogeneous mixture of a solute and a solvent. 23–26.Figure 1: Types of Mixtures: Solutions (salt and water), Suspensions (soil and water), and Colloids (milk) (from left to right) National Meet., San Francisco, CA, 1997, pp. Rahimi, P., Dettman, H., Nowlan, V., and DelBianco, A., Prepr.

The conversion of the >500°С fraction in the presence of the catalyst decreases this is probably due to saturation and neutralization with active hydrogen of primary radicals that are generated in the course of thermal degradation, initiate the chain reaction of thermal cracking, and favor its propagation.Īlshareef, A.H., Energy Fuels, 2020, vol. With an increase in the МoS 2 content of the dispersed catalyst, its activity in inhibition of chain reactions of thermal cracking, yielding resins, asphaltenes, and coke, increases. Catalyst particles with different ratios of the Mo sulfide and oxide phases were prepared ex situ. Experiments were performed in a flow-through reactor under the conditions of hydroconversion with the addition of a sulfur donor to the feed. The vacuum residue from petroleum distillation and heavy crude were used as the feedstock. Suspensions of catalyst particles were prepared from inverse emulsions of aqueous solutions of the precursor, ammonium paramolybdate, directly in the feed in the course of hydroconversion ( in situ), or the catalyst suspension was synthesized in advance ( ex situ) and then was added to the feed. The influence of the phase composition of the dispersed molybdenum catalyst on the transformation of high-molecular-mass components (resins and asphaltenes) in the course of hydroconversion of heavy petroleum feedstock was studied.
