- This program is a continuation of the Liquid Phase Methanation/Shift Program (EX-76-C-01-2036) which was completed on November 30, 1978. One of its primary goals is to study the rates of carbon formation during methanation over a wide range of process conditions and determine the effect of the carbon deposition on catalyst activity and selectivity. The second goal is to perform an engineering design of a hydrodynamic cold-flow unit of scale equivalent to the LPM/S pilot plant reactor for evaluation of the 3-phase reaction system hydrodynamics. Work to date has concentrated on the first task - Rates of Carbon Formation. The existing reaction units and analytical system have been refurbished and calibrated. Five nickel-based methanation catalysts were chosen as representative of the types available commercially. Carrier materials for the catalysts are alumina, kieselguhr and calcium aluminate. Nickel contents vary from 35 to 60% Ni. The first experimental scan, 100 hours - without steam, has been successfully completed. The second scan is in progress, 300 hours - without steam. Samples of both spent and virgin reduced catalysts have been sent out for analysis.
