Process for producing alcohols by acid treating olefinic mineral oils

Claim 1

FOR THE TREATMENT OF CRACKED HYDROCARBON DISTILLATES CONTAINING IMPURITIES (1) OF THE CLASS CONSISTING OF WATER SOLUBLE ALIPHATIC ACIDS AND NITROGENOUS COMPOUNDS, (2) SULFUR COMPOUNDS, ORGANIC ACIDS AND PHENOLIC COMPOUNDS, (3) LOWER MOLECULAR WEIGHT OLEFINS AND DIOLEFINS SULFATABLE BY DILUTE ACID AND HYDROLYZABLE TO FORM CORRESPONDINGLY LOWER MOLECULAR WEIGHT ALCOHOLS, AND (4) HIGHER MOLECULAR WEIGHT OLEFINS SULFATABLE BY CONCENTRATED ACID TO FORM CORRESPONDINGLY HIGH MOLECULAR WEIGHT ALCOHOLS, THE PROCESS THAT INCLUDES FIRST WATER WASHING SAID DISTILLATE TO REMOVE THEREFROM WATER SOLUBLE IMPURITIES INCLUDING SAID ALIPHATIC ACIDS AND NITROGENOUS COMPOUNDS, SEPARATING THE WASH WATER FROM THE DISTILLATE, THEN IN A SECOND STAGE REMOVING SULFUR COMPOUNDS, ORGANIC ACID AND PHENOLIC IMPURITIOES FROM THE WASHED DISTILLATE, CONTACTING THE DISTILLATE WITH A WATER SOLUTIOIN OF BETWEEN 1% TO 50% SULFURIC ACID TO SULFATE LOWER MOLECULAR WEIGHT OLEFINS AND DIOLEFINS IN THE DISTILLATES AND FORM LOWER MOLECULAR WEIGHT ALCOHOLS BY HYDROLYSIS OF THE SULFATED COMPOUNDS, CONTACTING THE RESULTING DISTILLATE WITH SOLID ADSORBENT TO SELECTIVELY ADSORB THEREON THE ALCOHOLS FORMED, SEPARATING THE DISTILLATE FROM THE ADSORBENT, RECOVERING THE ALCOHOLS FROM THE ADSORBENT, TREATING THE DISTILLATE IN A FINAL TREATING STAGE WITH CONCENTRATED SULFURIC ACID SOLUTION TO REMOVE THEREFROM SULFUR COMPOUNDS AND FORM SULFATED OLEFIN, AND SEPARATING THE RESULTING ACID LIQUOR FROM THE DISTILLATE.
