Gas detection in well logging

Claim 1

THE METHOD OF DETECTING METHANE IN AN AIR-GAS MIXTURE SUBJECT TO CONTAINING METHANE, HIGHER HYDROCARBONS, AND HYDROGEN WHICH COMPRISES: MAINTAINING A PERMEABLE BED OF A CATALYST CONSISTING ESSENTIALLY OF PELLETS OF ALUMINA WHICH HAVE BEEN HEATED TO WITHIN A RANGE OF 250*F. TO 350*F. FOR AT LEAST TWO HOURS AND IMMEDIATELY THEREAFTER QUENCHED WITH A DILUTE AQUEOUS SOLUTION OF CHLORIDES CHOSEN FROM THE GROUP CONSISTING OF PLATINUM AND RUTHENIUM CHLORIDES AND THEREAFTER HEATED TO WITHIN A RANGE OF 250*F. TO 350*F. FOR AT LEAST THREE HOURS, AT A CATALYST BED TEMPERATURE SUFFICIENTLY HIGH TO COMPLETELY COMBUST HYDROGEN AND HIGHER HYDROCARBONS BUT SUFFICIENTLY LOW AS TO COMPLETELY FAIL TO COMBUST METHANE, PERMEATING SAID AIR-GAS MIXTURE THROUGH SAID CATALYST BED, WHILE MAINTAINED WITHIN SAID TEMPERATURE RANGE, SO AS TO COMPLETELY COMBUST THE HYDROGEN AND HIGHER HYDROCARBONS IN SAID MIXTURE AND THEREAFTER ANALYZING SAID PERMEATED AIR-GAS MIXTURE FOR METHANE.

Claim 2

THE METHOD OF DETECTING METHANE IN AN AIR-GAS MIXTURE SUBJECT TO CONTAINING METHANE, HIGHER HYDROCARBONS, AND HYDROGEN WHICH COMPRISES: MAINTAINING A PERMEABLE BED OF A CATALYST CONSISTING ESSENTIALLY OF PELLETS OF ALUMINA WHICH HAVE BEEN HEATED TO WITHIN A RANGE OF 250*F. TO 350*F. FOR AT LEAST TWO HOURS AND IMMEDIATELY THEREAFTER QUENCHED WITH A DILUTE AQUEOUS SOLUTION OF CHLORIDES CHOSEN FROM THE GROUP CONSISTING OF PLATINUM AND RUTHENIUM CHLORIDES AND THEREAFTER HEATED TO WITHIN A RANGE OF 250*F. TO 350*F. FOR AT LEAST THREE HOURS, AT A CATALYST BED TEMPERATURE SUFFICIENTLY HIGH TO COMPLETELY COMBUST HYDROGEN AND HIGHER HYDROCARBONS BUT SUFFICIENTLY LOW AS TO COMPLETELY FAIL TO COMBUST METHANE, PERMEATING SAID AIR-GAS MIXTURE THROUGH SAID CATALYST BED, WHILE MAINTAINED WITHIN SAID TEMPERATURE RANGE, SO AS TO COMPLETELY COMBUST THE HYDROGEN AND HIGHER HYDROCARBONS IN SAID MIXTURE AND THEREAFTER ANALYZING SAID PERMEATED AIR-GAS MIXTURE FOR METHANE.
