The enzyme biorefinery platform for advanced biofuels production

Engineering aspects of hydrothermal pretreatment: From batch to continuous operation, scale-up and pilot reactor under biorefinery concept

“…In our biorefinery research group (www.biorefinerygroup.com), the design and operation of a pilot-scale tubular steam explosion batch reactor has been developed for the fractionation of biomass in terms of biorefinery (Singh et al 2019). The design of the SE reactor was developed in three main stages: 1) The conceptual engineering design consisted mainly on the initial study of feasibility and the definition of the bioreactor basic requirements; 2) Basic engineering design consisted on the definition of the definitive requirements of the reactor, including all the basic specifications, such as, needed components, operational strategies, technical and even economical evaluation of the equipment; 3) the detailed engineering design consisted on the verification of the reactor performance to confirm compliance with the purpose of its design.…”

Bioenergy from biofuel residues and waste

“…They also concluded because of the scale of its domestic bioethanol and biodiesel production, Brazil can now be thought of as one of the global leaders in sustainable biofuel production. Singh et al (2019) focused on the recent development of numerous processes involving enhanced enzymatic hydrolysis and enzyme production for more efficient and cost-effective biorefinery processing. It was found that hydrothermal pretreatment made cellulose more accessible to enzymes which resulted in enhanced enzymatic hydrolysis where submerged fermentation and coculturing processes enhanced enzyme's production in addition to its efficiency in a more Eco-friendly and cost-effective way.…”

Hot Compressed Water Pretreatment and Surfactant Effect on Enzymatic Hydrolysis Using Agave Bagasse

“…Lately, bioethanol has been considered a key alternative to overcome fossil fuels dependence. However, bioethanol commercialization is still unfeasible due to high production costs related mainly to enzymatic hydrolysis of the cellulose contained in the cell wall of the plants into soluble sugars for subsequent fermentation [3,4]. Many factors preclude cellulosic enzymatic hydrolysis for large-scale bioethanol production from lignocellulosic materials [5].…”
