Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
118 words
IN THE PROCESS FOR THE OXCHLORINATION OF HYDROCARBONS SELECTED FROM THE GROUP CONSISTING OF OLEFINIC HYDROCARBONS AND SATURATED HYDROCARBONS BY REACTION OF THE HYDROCARBON, OXYGEN AND HYDROGEN CHLORIDE AT ELEVATED TEMPERATURE WITHIN THE RANGE OF 250-550*C. AND IN THE PRESENCE OF A DEACON TYPE CATALYST, THE STEPS OF PASSING THE HYDROGEN CHLORIDE, OXYGEN AND HYDROCARBON IN ADMIXTURE THROUGH A FLUID BED OF CATALYST TO ACHIEVE 40-80 PERCENT CONVERSION IN A FIRST PHASE AND THEN DIRECTLY PASSING THE EFFLUENT FROM THE FIRST PHASE THROUGH A STATIONARY CATALYTIC BED AT A REACTION TEMPERATURE HIGHER THAN THE REACTION TEMPERATURE IN THE FIRST PHASE AND WHEREIN THE CONVERSION REACTION IS CONTINUED TOWARDS COMPLETION TO PRODUCE THE DESIRED OXYCHLORINATED HYDROCARBON AS A PRODUCT.
