Brazil and US partner on bioethanol production

Brazilian company CTBE will use US technology to increase bioethanol yield from sugarcane

Sugarcane biomass will be used to produce cellulosic ethanol

A Brazilian laboratory has chosen a US technology for a biomass research and development in an attempt to raise the production of bioethanol. The technology could raise yield of the biofuel by as much as 40 per cent.

Brazilian Bioethanol Science and Technology Laboratory, CTBE, selected Ohio’s firm AdvanceBio Systems’ SuPR2G Laboratory Scale Pretreatment Reactor for the R&D biomass project that should extend the output of bioethanol from sugarcane.

The US reactor produces fermentable sugars, biofuels and chemicals from lignocellulose rich biomass feedstocks. “The equipment will be used for research, development and demonstration of technology related to the production of biomass-based fuels and chemicals from lignocellulosic feedstocks in our Pilot Plant for Process Development,” according to Carlos Eduardo Vaz Rossell, industrial program director at CTBE.

“By partnering with CTBE, we are contributing to the development of technology to produce cellulosic ethanol from sugarcane biomass and increasing the bioethanol yield from sugarcane in excess of 30 to 40 per cent”, said Dale Monceaux, a principal of AdvanceBio Systems.

AdvanceBio Systems’ reactor incorporates the “zero hold-up discharger” and is able to operate in either slurry or pneumatic product removal modes.  The SuPR2G system hydrolyses a range of agricultural feedstocks such as sugarcane, bagasse, corn stover and switchgrass.

“CTBE and AdvanceBio Systems intend to collaborate in CTBE’s R&D effort, not only in pretreatment, but also with other interrelated technologies,” said Rossell.
