    Abstract: A peaking process is disclosed for preparing aldehydes or carboxylic acids from a mixture of alpha olefins. The alpha olefins are separated into at least two fractions consisting of a low molecular weight fraction and a high molecular weight fraction. The high molecular weight fraction is isomerized and the two fractions oxidized. The low molecular weight fraction will oxidize to Cn 1 product and C1 product. The high molecular weight fraction will cleave at the double bond giving products containing the number of carbon atoms of the groups on either side of the double bond. The procedure has great versatility by varying the number of fractions and isomerizations. With alpha olefins prepared from metal alkyl growth product, M-values also have an influence on the final product.

    Abstract translation: 公开了从α-烯烃的混合物制备醛或羧酸的峰值过程。 将α-烯烃分成由低分子量级分和高分子量级分组成的至少两个级分。 高分子量级分异构化，两部分被氧化。 低分子量馏分将氧化成Cn-1产物和C1产物。 高分子量级分将在双键处裂解，得到含有双键两侧基团碳原子数的产物。 该程序通过改变分数和异构化的数量具有很大的通用性。 使用由金属烷基生长产物制备的α-烯烃，M值也对最终产物有影响。

    Abstract: A METHOD IS DISCLOSED FOR THE OXYGENATION OF LIQUID HYDROCARBON COMPOUNDS TO FATTY ACIDS AND OTHER OXYGENATED COMPOUNDS BY ATOMIZING A PREHEATED AND PRESSURIZED MIXTURE OF THE HYDROCARBON STEAM, AND AIR TO A VAPORFOAM, AND PASSING SUCH VAPOR-FOAM MIXTURE THROUGH A CATALYTIC BED AT A TEMPERATURE ABOVE ATMOSPHERIC TEMPERATURE BUT BELOW THE BOILING POINT OF THE HYDROCARBON. THE VAPOR-FOAM IS USAUALLY A COMBINATION OF VAPOR AND FOAM BUT MAY BE ALL FOAM OR SUBSTANTIALLY ALL VAPOR. SEVERAL FORMS OF APPARATUS ARE DISCLOSED. IN EACH FORM DISCLOSED A REACTION VESSEL IS PROVIDED HAVING A CATALYTIC BED THEREIN AND AN ATOMIZER IS PROVIDED WITHIN THE VESSEL IN ORDER TO FORM THE LIQUID INTO A VAPOR-FOAM PRIOR TO PASSAGE THROUGH THE CATALYTIC BED. IN TWO OF THE APPARATUS, THE HYDROCARBON MATERIAL, STEAM, AND AIR ENTER THE REACTION VESSEL, AND ARE ATOMIZED NEAR THE TOP THEREOF AND THEN PASS THROUGH THE CATALYTIC BED AND MOVE OUT OF THE REACTION VESSEL AT THE BOTTOM, GOING FROM THERE TO AN ACCUMULATOR WHERE THE PRODUCT IS SETTLED AND SEPARATED. IN ONE ARRANGEMENT, THE FLOW IS REVERSED SO THAT THE MATERIALS MOVE UPWARD THROUGH THE REACTION VESSEL. SEVERAL TYPES OF HEAT EXCHANGERS ARE SHOWN FOR PREHEATING THE MATERIALS TO BE REACTED EITHER UTILIZING THE HEAT FROM THE REACTION (WHICH IS NORMALLY EXOTHERMIC) OR UTILIZING HOT WATER OR STEAM.
