Influence of carbon chain length of fatty acid methyl ester (FAME) on product distribution in catalytic cracking process was investigated in a fixed-bed microreactor at various temperatures. Octanoic acid methyl ester (OAME)

decanoic acid methyl ester (DAME) and lauric acid methyl ester (LAME) were used as feeds

meanwhile LVR-60 was selected as catalyst. Results showed that with the increase of carbon number of fatty acid methyl ester (FAME)

the conversion of FAME increased. Moreover

the content of CO and CO2 from the deoxygenation of FAME and content of hydrocarbons in the liquid product had similar trends

while the content of oxygen-containing compound (OCC) in liquid product decreased. In addition

raising reaction temperature was beneficial for the conversion of FAME

resulting in more hydrocarbons and lower oxygen-containing compound (OCC) content in liquid product. At lower temperature

CO2 was the main product of deoxygenation

and aldehydes

esters

carboxylic acids and ketones were the main organic oxygenated compounds generated from catalytic cracking of FAME. However

at higher temperature

liquid products contained scarcely any organic oxygenated compounds

and CO was the main product of deoxygenation.
