Abstract: IN A PROCESS FOR CRACKING A PETROLEUM DERIVED NAPHTHA HAVING A BOLING RANGE OF 90 TO 400*F. AND A SPECIFIC GRAVITY OF 0.65 TO 0.78 TO ALKENES AND ALKANES; THE INSTANT INVENTION RELATES TO AN IMPROVEMENT COMPRISING ADMIXING ABOUT 1.0 TO 35 PARTS BY WEIGHT OF H2S (OR AN AMOUNT OF A COMPOUND WHICH YIELDS AN SH RADICAL IN HE CRACKING ENVIRONMENT SUFFICIENT TO YIELD THAT AMOUNT OF H2S) PER 100 PARTS BY WEIGHT OF ALKANE AND H2S (OR A PRECURSOR THEREOF) IN THE MIXTURE CONSISTING ESSENTIALLY OF H2S (OR THE PRECURSOR THERETO) AND THE NAPHTHA TO BE CRACKED, AND THEN PASSING THE RESULING MIXTURE THROUGH A REACTOR MAINTAINED AT A TEMPERATURE O ABOUT 1100* F. TO ABOUT 2000*F. WITH A RESIDENCE TIME OF ABOUT 0.25 TO ABOUT 2.0 SECONDS AND A PRESSURE OF ABOUT 0 TO ABOUT 65 P.S.I.G. STEAM IS ALSO EMPLOYED.

Abstract: A method of reducing the shear degradation when pumping through conduits, such as well tubing during hydraulic fracturing operations and pipelines, a liquid containing a friction loss reducing additive comprising adding to the liquid the friction loss reducing additive at least partially in chunk or granular form so that the additive is present at least partially in chunk or granular form when the mixture is passed through the pump.
