Hindered Diffusion of Asphaltenes at Elevated Temperature and Pressure Progress Report

Description: During this time period work proceeded in two main areas, the performance and analysis of petroleum asphaltene diffusional uptake experiments at 325 C and the preparation and testing of some new carbon based catalysts. In the first area, we performed studies of the diffusion controlled uptake of petroleum asphaltenes into a porous carbon catalyst at 325 C. The experiments were performed under an inert He atmosphere using 1-methylnaphthalene as a solvent. These purpose of these experiments was t… more

Hindered Diffusion of Asphaltenes at Elevated Temperature and Pressure Progress Report

Description: During this past six months we continued our ongoing studies of the diffusion controlled uptake of coal and petroleum asphaltenes into a porous carbon catalyst. Toluene was used as the solvent for experiments at 20 C and 75 C while 1-methylnaphthalene was the solvent for the higher temperature experiments at 100 C, 150 C and 250 C. All runs were made at a pressure of 250 psi (inert He gas). Experiments were performed at 20 C and 75 C, for the petroleum asphaltene/toluene system. For the coal as… more
