Solvent-free, integrated process for by-products from fats and lipid manufacturing |
| 초록 |
Manufacturing lipid products from natural resources normally yields significant amounts of low-value fats and oils next to the focused high valued processes. With better refining technologies these rests can be turned into value added products or at least converted into useful energy sources. Fats are possible to be converted into glycerine and fatty acid esters by alcoholysis. Fatty acid esters can be used instead of petroleum in ovens or diesel engines to provide thermal or electrical energy while glycerine is a raw material for the chemical industry. An alternative to the chemical hydrolysis process, the biochemical conversion by lipase is easy to carry out. Such a process can generate fatty acid monoglycerides next to fatty acid esters. Carried out in a supercritical carbon dioxide, enzymatic reactions can perform at higher mass transfer rates than under classical conditions. Next to this, supercritical carbon dioxide can be used to extract different products in the substrate continuously. The pressure and temperature of the supercritical fluid can be chosen in a way that only the generated fatty acid esters are withdrawn from the reaction mixture. |
