Hydrogenation of soybean oil and cottonseed oil with nickel catalyst in the presence of catalyst poisons was investigated. Catalyst poisons (carbon monoxide, non-sulfur contained amino acids and sulfur contained amino acids) greatly affected the activity of the catalyst. Though carbon monoxide deactivated the catalyst below 180°C, it did not deactivate the catalyst over 220°C. It was found that trans isomer slightly increased when carbon monoxide was introduced. Non-sulfur contained amino acids deactivated the catalyst weaker than sulfur contained amino acid did and affected no increase of trans isomer. Sulfur contained amino acid deactivated the catalyst intensively and affected increase of trans isomer. Selectivities (S<SUB>31</SUB>, S<SUB>21</SUB>) during hydrogenation by nickel catalyst with carbon monoxide or sulfur contained amino acid were substantially equal to those by nickel catalyst without catalyst poison.
