An invention patent was granted by the United States Patent and Trademark Office


Recently, an invention “Process for hydrolysed reforming of liquous cellulose biomass to produce bio-gasoline” was granted to Guangzhou Institute of Energy Conversion CAS by the United States Patent and Trademark Office. This patent was invented by Professor Longlong Ma and his work team. This invention was applied as PCT patent in 2010, and was applied in the United States and European Union in 2012. In the same year, this patent was authorized by the State Intellectual Property Office of the PRC. This is the first granted United States patent obtained by Guangzhou Institute of Energy Conversion.

This invention discloses a process for the production of bio-gasoline from hydrolyzed ligneous cellulose biomass, which directly transfers the hydrolyzed-material liquid obtained from ligneous cellulose biomass through hydrolyzing into aqueous catalytic reforming system, the feed subjects to aqueous catalytic reforming reaction in low-temperature reforming reactor and in high-temperature reforming reactor in turn. The soluble carbohydrates contained in hydrolysate are converted into bio-gasoline, which can be easily phase-separated from aqueous phase through phase-separator. Bio-gasoline is obtained in the upper layer of the phase-separator. The invention creates a new process for producing high-quality liquid fuel oil using biomass as feedstock, which can automatically layer and separate, omitting the step of rectifying and purifying product. The feedstock is cheap and broadly available. The product can directly used in the present vehicle-carried engine system, and have prosperous market prospect.
