摘要： 1. A PROCESS FOR THERMALLY CRACKING A HYDROCARBON FEEDSTOCK TO CONVERT IT INTO LOWER MOLECULAR WEIGHT PRODUCTS CONTAINING LARGE PROPORTIONS OF OLEFINS COMPRISING CONDUCTING SAID PROCESS IN A HEATED REACTOR UNDER SUPERATMOSPHERIC PRESSURES, RANGING FROM ABOUT 10 BARS TO ABOUT 70 BARS READ AT THE REACTOR OUTLET, IN THE PRESENCE OF HYDROGEN USED IN SUCH AMOUNTS THAT ITS MOLAR CONCENTRATION IN THE EFFLUENT FROM THE CRACKING SECTION BE NOTLOWER THAN 20%, AT REACTOR OUTLET TEMPERATURES HIGHER THAN ABOUT 625*C. TO ABOUT 1100*C. AND WITHIN RESIDENCE TIME WITHIN THE REACTION SECTION SHORTER THAN ABOUT 0.5 SECOND DOWN TO ABOUT 0.005 SECOND, ADJUSTING SAID RESIDENCE TIME IN A DECREASING MANNER WITH AN INCREASE OF THE CRACKING TEMPERATURE, AND PROVIDING AN EFFICIENT MEANS TO CONTROL THE EXTEND OF THE DESTRUCTIVE AND HYDROGENATING ACTION OF HYDROGEN UNDER PRESSURE AS WELL AS THE CORRELATED HEAT EFFECT, SO THAT COKING AND USELESS OVER-HYDROGENATION OF PRIMARY CRACKING PRODUCTS INTO PARAFFINS ARE AVOIDED, WHILE OBTAINING CONTROLLED HEAT RELEASE CAPABLE OF SUBSTANTIALLY REDUCING THE OVER-ALL HEAT REQUIREMENTS OF THE CRACKING PROCESS.
