Abstract: Metal oxides-silica composite materials are synthesized by a co-precipitation method to serve as modified catalysts for converting ethanol into four-carbon hydrocarbons. The method includes mixing a liquid-phase silicon source and a metal precursor at different ratios so as to change the acid-base composition of the composite materials and thereby increase selectivity with respect to the four-carbon products.

Abstract: Disclosed is a modified carbonaceous material, which includes hexagonal carbon networks in a layered stacking structure and acidic functional groups bonded to the hexagonal carbon networks and mainly existing at edges of the layered carbonaceous structure. Accordingly, the close proximity of acid moiety at the edges can resemble the center of hydrolysis enzymes, resulting in enhancement of hydrolytic efficiency. Additionally, the acid-functionalized carbonaceous material can also be applied in the capture and storage of carbon dioxide due to its unexpectedly higher capacity for CO2 molecular.

Abstract: This invention relates to a novel molten salt system in chemical transformation of saccharides and a method as well as an apparatus for multi carbon production by the molten salt system. It is found that an eutectic molten salt composition is advantageous for multi-carbon productions through chemical transformation under mild conditions. This invention further provides a method and an apparatus for preparing 5-hydroxymethylfurfural (HMF) and HMF-derived chemicals from saccharides by the said molten salt system.
