Process for the conversion of gas produced by pressure gasification

Claim 1

PROCESS FOR REPRODUCING LONG-DISTANCE FUEL GAS, WHICH COMPRISES COOLING HOT CRUDE FUEL GAS HIGH IN CARBON MONOXIDE AND ATTENDANT IMPURITIES OBTAINED BY PRESSURE GASIFICATION OF SOLID CARBON-CONTAINING FUELS WITH STEAM AND OXYGEN TO A TEMPERATURE OF 190 TO 210*C. BY CONTACTING THE SAME UNDER PRESSURE WITH A MEMBER SELECTED FROM THE GROUP CONSISTING OF STEAM, OIL TAR, AND MIXTURES THEREOF, WHEREBY THE HIGH BOILING PRODUCTS, REACTIVE ASPHALTIC MATERIALS, RESIN-FORMING IMPURITIES, WATER, TARS, PITCHES, AND LIKE MATERIALS FORM A CONDENSATE, CONDUCTING THE CRUDE GAS AFTER SEPARATION THEREFROM OF SAID CONDENSATE AT THE CONVERSION TEMPERATURE AND AT SUBSTANTIALLY THE SAME PRESSURE AS THE PRESSURE OF THE STARTING HOT CRUDE GAS OVER A CONVERSION CATALYST TO THEREBY CONVERT THE HIGH CONTENT OF CARBON OMNOXIDE AND STEAM UNUSED IN THE PRESSURE GASIFICATION CONTAINED IN SAID CRUDE GAS TO CARBON DIOXIDE AND HYDROGEN, RECOVERING THE LOW CARBON MONOXIDE CONTENT FUEL GAS, THEREAFTER COOLING AND SCRUBBING THE CONVERTED GAS TO REMOVE THEREFROM FURTHER IMPURITIES SSUCH AS HYDROGEN SULFIDE, ORGANIC SULFUR COMPOUNDS, AMMONIA, HYDROCYANIC ACID AND NITRIC ACID, ADMIXING SAID PURIFIED GAS WITH GASES HAVING HIGHER CALORIFIC VALUES THAN SUCH PURIFIED GAS TO THEREBY FORM A LONG-DISTANCE FUEL GAS HAVING A CONDENSATE BELOW THAT OF COKE OVEN GAS.
