Process for the production of rich fuel to replace natural gas by means of catalytic hydrogasification under pressure of fluid hydrocarbons
Abstract
Abstract A MIXTURE OF METHANE AND HYDROGEN WHICH IS INTERCHANGEABLE WITH NATURAL GAS, IS OBTAINED FROM LIQUID HYDROCARBONS BY MEANS OF A TWO-STEP CATALYTIC HYDROGENATION PROCESS UNDER PRESSURE. IN THE FIRST STEP A COMPLETE GASIFICATION, BUT NOT A COMPLETE HYDROGENATION, IS EFFECTED BY CONTACTING THE LIQUID HYDROCARBONS WITH A MILDHYDROGENATING CATALYST IN SUCH A CONTROLLED CONDITION OF TEMPERATURE, PRESSURE, HYDROGEN-TO-CARBON RATIO AS TO OBTAIN A GAS CONTAINING 10-60% BY VOLUME OF FREE HYDROGEN. IN THE SECOND STEP THE GAS OBTAINED IN THE FIRST STEP IS PRACTICALLY COMPLETELY HYDROGENATED TO METHANE ON A CATALYST HAVING HIGH HYDROGENATING AND METHANATING ACTIVITY. THE RESULTANT PRODUCT IS ESSENTIALLY METHANE WITH UP TO 12 VOLUME PERCENT HYDROGEN.
