Claim 1
Independent Claim
96 words
A PROCESS FOR MAKING AN ETHANE-RICH GAS WHICH COMPRISES HYDROGENATING A FOSSIL FUEL TAKEN FROM THE GROUP CONSISTING OF OIL SHALES, TORBANITES, CANNEL COALS AND ASPHALTITES IN A REACTION VESSEL IN THE PRESENCE OF AT LEAST 50% OF THE STOICHIOMETRIC QUANITY OF HYDROGEN REQUIRED TO CONVERT ALL OF THE ORGANIC CARBON AND HYDROGEN IN THE FOSSIL FUEL TO METHANE AT A REACTION TEMPERATURE OF 1100* TO 1300*F. AND A PRESSURE OF OVER 1000 POUNDS PER SQUARE INCH GAUGE, REMOVING THE PRODUCT GAS FROM THE VESSEL UPON ATTAINING REACTION TEMPERATURE, AND SEPARATING ETHANE FROM THE PRODUCT GAS.
