Claim 1
Independent Claim
124 words
A PROCESS OF PRODUCING AN IMPROVED DIESEL FUEL COMPONENT FROM A MIXTURE CONTAINING NONOXYGENATED AND OXYGENATED HYDROCARBON COMPOUNDS CONTAINING REACTIVE OXYGEN MEASURABLE IN TERMS OF THE OXYGEN FACTOR TEST AND EXHIBITING A CORRESPONDINGLY HIGH CETANE NUMBER VALUE WHICH COMPRISES SEPARATING NON-OXYGENATED HYDROCARBONS FROM SAID OXYGENATED HYDROCARBONS TO PRODUCE A CONCENTRATE OF THE LATTER, AND CONTACTING SAID CONCENTRATE WITH A STRONGLY ACIDIC REAGENT UNDER MILD CONDITIONS INCLUDING A TEMPERATURE OF BELOW 150*F. AND A RELATIVELY SHORT CONTACT TIME OF LESS THAN ABOUT 90 MINUTES TO CONVERT SAID OXYGENATED HYDROCARBONS TO MORE STABLE OXYGENATED HYDROCARBONS HAVING A HIGH CETANE NUMBER VALUE AND A REDUCED OXYGEN FACTOR, SAID STRONGLY ACIDIC REAGENT BEING SELECTED FROM THE GROUP CONSISTING OF SULFURIC ACID, NITRIC ACID, PHOSPHORIC ACID AND HYDROCHLORIC ACID.

Claim 3
Dependent Claim
107 words
A DIESEL TYPE MOTOR FUEL COMPONENT COMPRISING AS THE ACTIVE INGREDIENT A LIQUID OXYGENATED HYDROCARBON CONVERSION PRODUCT OF TREATMENT OF PARTIALLY OXYGENATED HYDROCARBONS CONTAINING CHEMICALLY COMBINED REACTIVE OXYGEN SUFFICIENT TO GIVE A RELATIVELY HIGH OXYGEN FACTOR AND HAVING A HIGH CETANE NUMBER WITH A STRONGLY ACIDIC REAGENT SELECTED FROM THE GROUP CONSISTING OF SULFURIC, NITRIC, PHOSPHORIC AND HYDROCHLORIC ACIDS UNDER MILD CONDITIONS OF A LOW TEMPERATURE BELOW ABOUT 150*F. AND A SHORT CONTACT TIME OF LESS THAN ABOUT 90 MINUTES, SAID PRODUCE BEING RELATIVELY STABLE RELATIVELY NON-CORROSIVE, SOLUBLE IN HYDROCARBONS N THE DIESEL FUEL RANGE AND HAVING A RELATIVELY LOW OXYGEN FACTOR AND A HIGH CETANE NUMBER.
