Ethanol is a renewable energy resource derived from the domestic resources like the waste tissue paper, corn, wheat straw, algae, food and newspaper waste mixture and also from paper waste. Present study deals with the Production of Ethanol from the waste tissue paper by the simultaneous ...
The process of ethanol production from distilled grain waste based on concentrated H 2 SO 4 saccharification was then studied. The process mainly consisted of concentrated H 2 SO 4 saccharification, solid–liquid separation, decoloration, sugar–acid separation, oligosaccharide hydrolysis, and continuous...
Ethanol production from the hydrogenation of acetic acid requires energy to drive the hydrogenation reaction and the purification of the crude ethanol product. Heat integration process to recover heat from one part of the production process to be used within the process improves efficiencies and reduces...
The invention relates to the production of ethanol by fermentation according to the process consisting in separating the wine obtained by fermentation into a yeast-enriched stream, which is recycled into the fermenter, and a stream practically free of yeast cells, at least part of which is sent ...
The process of the present invention is performed with grains of cereals like maize, sorghum or any starchy cereal or a mixture thereof for producing high performance ethanol, the process comprising the following steps: steam flaking cereal grains, dry-milling the flakes, liquefying the flour with...
1. A process for the production of ethanol comprising the steps: (a) contacting an ethene-ethane mixture and water with a hydration catalyst in a reaction zone under conditions which result in the production of a gaseous product containing ethanol, unreacted ethene and ethane; ...
2,2,2 - Trifluoroethanol is prepared by reacting hydrogen with 2,2,2-trifluoroethyl trifluoroacetate in the vapour phase at a temperature of 200 DEG to 400 DEG C. in the presence as catalyst of (1) a mixture of chromium oxide and a second hydrogenating metal oxide of (2) a noble met...
Lignocellulosic biomass is pre-treated to provide crude monosaccharides and crude polysaccharides, which are then hydrolysed in the presence of at least one enzyme to provide crude
