A process for forming a carrier material

Abstract: A support containing methylaluminoxane and derivatives thereof is formed by an incipient impregnation of a silica support so that the solution of the aluminoxane fills the pores in the support with no solution left out. The supported aluminoxane eliminates the problem of fluid bed reactor fouling during gas phase polymerization of olefins in the presence of added metallocenes. The fluid bed reactor (10) is a vertical enclosure with a reaction zone (12), comprising a bed of growing polymer particles and a minor amount of catalyst particles fluidized by the continuous flow of polymerizable and modifying gaseous components, a velocity reduction zone (14), where entrained particles are given opportunity to drop back into the fluidized bed, and a distributor plate (20). The unreacted gas passes through a cyclone separator (22), a filter (24), a compressor (25) and a heat exchanger (26). The distribution plate (20) serves the purpose of diffusing recycle gas through the bed at a rate sufficient to maintain fluidization.

Sweep Improvement in CO2 Flooding by Use of Foaming Agents

Abstract: Les agents moussants, qui sont des sels d'ammonium d'alcool sulfate et ethoxyle, sont selectionnes en fonction de leur stabilite, testee en laboratoire. L'influence de ces agents sur les performances de la recuperation assistee par injection de dioxyde de carbone est etudiee sur des carottes

Pulsed Nmr study of the temperature hysteresis in the agar-water system

Abstract: A large temperature hysteresis is observed in the nmr relaxation times of the water and agar hydrogen nuclei which corresponds to that of the sol-gel transition. Self-diffusion measurements of the water in the gel state indicate that the motions of the great majority of the water molecules are essentially unaffected by the presence of the agar molecules. These results indicate that the major portion of the water molecules in the agar-water system is not in an “icelike” or modified state.
