Hindered diffusion of asphaltenes at evaluated temperature and pressure: Semiannual technical report, September 20, 1996-March 20, 1997

PDF Version Also Available for Download.

Description

During this time period, the high temperature/high pressure autoclave, received from Parr Instrument Company, has been set up and checked out. A detailed autoclave operation procedure was developed and implemented. The system reproducibility was verified by performing several runs for the uptake of quinoline in mineral oil onto Al{sub 2}0{sub 3} indicating that the system is reproducible, with an error of less than 10%. The effect of external mass transfer was studied by the uptake of quinoline in mineral oil onto Al{sub 2}0{sub 3} at different stirring speeds, varying from 100 rpm to 800 rpm. The results showed that when ... continued below

Description

During this time period, the high temperature/high pressure autoclave, received from Parr Instrument Company, has been set up and checked out. A detailed autoclave operation procedure was developed and implemented. The system reproducibility was verified by performing several runs for the uptake of quinoline in mineral oil onto Al{sub 2}0{sub 3} indicating that the system is reproducible, with an error of less than 10%. The effect of external mass transfer was studied by the uptake of quinoline in mineral oil onto Al{sub 2}0{sub 3} at different stirring speeds, varying from 100 rpm to 800 rpm. The results showed that when the stirring speed was greater than 100 rpm, the effect of external mass transfer was negligible. Objectives 1. To investigate the hindered diffusion of coal and petroleum asphaltenes in the pores of catalyst particles at elevated temperature and pressures. 2. To examine the effects of concentration, temperature, solvent type, and pressure on the intraparticle diffusivity of asphaltenes.
