CATALYTIC ISOMERIZATION OF PARAFFIN BASE HYDROCARBONS WITH DUAL FUNCTION METAL CATALYSTS IN THE FIELD OF DIESEL AND JET FUELS

Abstract

Isomerization and hydrocracking in the field were made with a soft paraffin wax to obtain products with properties similar to diesel and jet fuels. The catalyst used was 0,1 wt.% Pd on alumina-boria (4:1), as it gave the best isomerization results with n-hexane as starting material. Difficulties were encountered in the analysis of the reaction products. The analytical tool gas chromatography in combination with mass spectrometry was used. Experimental runs with nonane were conducted both in batch and continuous operations. The maximum yield of C-9 isomers was obtained for batch operations at a reaction temperature of 375 C and at a reaction time of 20 hr and for continuous operations at 425 C and 10 sec reaction time. The greater portion of C-9 isomers consisted of monomethyl isomers; the 2-, 3- and 4-methyloctanes were identified. From the dialkyl-isomers, the presence of 2, 3 dimethyl-, 2,5-dimethylheptane and 2-methyl 3-ethylhexane was confirmed.
