Catalytic pressure refining of hydrocarbons of low boiling point in the presence of a mixture of co and hydrogen

Claim 1

AN IMPROVED PROCESS FOR THE REMOVAL OF SUCH IMPURITIES AS SULFUR. OXYGEN AND NITROGEN COMPOUNDS BY THE CATALYTIC PRESSURE REFINING OF LOW BOILING POINT HYDROCARBONS AS INITIAL MATERIAL SELECTED FROM THE GROUP CONSISTING OF CRUDE BENZENES. CRUDE GASOLINES, CRUDE KEROSENES AND CRUDE GAS OILS WITH HYDROGEN CONTAINING CARBON MONOXIDE SUCH THAT THE PRODUCT OF SAID REFINING HAS SUBSTANTIALLY THE SAME BOILING RANGE AS THE INITIAL MATERIAL, WHICH COMPRISES CARRYING OUT THE REFINING WITH 0.2 TO 2.5 CUBIC METRES PER KILOGRAM OF INITIAL MATERIAL OF A HYDROGEN CONTAINING CARBON MONOXIDE GAS HAVING A CARBON MONOXIDE CONTENT FROM 4 TO 20% AT A HYDROGEN PARTIAL PRESSURE OF 10 TO 60 ATMOSPHERES, A THROUGHPUT OF 0.3 TO 2.5 KILOGRAMS OF CRUDE MATERIAL PER LITRE OF CATALYST VOLUME PER HOUR AND AN ADMISSION TEMPERATURE INTO THE REACTION ZONE OF 280*C. TO 450*C. IN SUCH MANNER THAT DURING THE REFINING SUCH AN AMOUNT OF CARBON MONOXIDE REACTS WITH HYDROGEN THAT A RISE IN TEMPERATURE OF AT LEAST 10*C. AND AT MOST 50*C. TAKES PLACE IN THE REACTION ZONE.
