1,3-butadiene (BD) is an important intermediate used for synthetic rubber, elastomers and polymeric resins manufacture[1]. BD is mainly obtained as a by-product of steam cracking of naphtha and gas oil for ethylene production. However, inrecent years this way of production of ethylene has been partly replace by lighter raw materials coming from shale gasand consequently the butadiene from non-renewable resources has decreased. Therefore, it is highly desirable to find analternative route starting from renewable feedstock. Between the alternative routes proposed, the dehydration of 1,3butanediol (1,3BDOL) using acid catalysts is becoming attractive for bio-BD production with high yields [2]. However, themain drawback is the formation of carbonaceous deposits that deactivate the catalysts. Therefore, the objective of thiswork was to study the coke formed during the 1,3-BDOL dehydration and how this affect the catalytic performance.
