Patent number: 9945000Abstract: Acid hydrolysis of biomass is an important step for releasing the component sugars before converting them to fuels and/or biochemicals. During such a process, a significant amount of mineral acid, such as sulfuric acid, is used. In most cases, the residual acid is neutralized with lime before the sugar conversion step. By doing so, a waste calcium sulphate stream is generated and sent to disposal. The efficient separation of acid from the sugars would allow the recycle of the acid and make the entire process more economically viable. We found that a resin bed packed with an acid retardation resin can be used to achieve an efficient separation (i.e. 98.5% recovery of the acid) of the sulfuric acid from the sugars. The resin bed can be simply regenerated with water.Type: GrantFiled: April 20, 2016Date of Patent: April 17, 2018Assignee: FPINNOVATIONSInventors: Naceur Jemaa, Michael Paleologou, Talat Mahmood

Patent number: 7008485Abstract: The invention relates to a process of separating compounds with a small molar mass from compounds having a molar mass less than 1.9 times that of the compounds with a small molar mass using nanofiltration. The compounds with a small molar mass have a typical molar mass less than 250 g/mol. In one embodiment of the invention, pentose sugars are separated from hexose sugars. The invention can be applied to the recovery of xylose from spent liquors and to the recovery of betaine from sugar beet pulp extracts, for example.Type: GrantFiled: December 28, 2001Date of Patent: March 7, 2006Assignee: Danisco Sweeteners OyInventors: Heikki Heikkila, Mika Manttari, Marianne Nystrom, Mirja Lindroos, Hannu Paananen, Outi Puuppo, Hannu Koivikko

Patent number: 6872316Abstract: The invention relates to a process of producing a xylose solution from a biomass hydrolysate by subjecting the biomass hydrolysate to nanofiltration and recovering as the nanofiltration permeate a solution enriched in xylose. The biomass hydrolysate used as starting material is typically a spent liquor obtained from a pulping process.Type: GrantFiled: December 28, 2001Date of Patent: March 29, 2005Assignee: Danisco Sweeteners OyInventors: Heikki Heikkilä , Mika Mänttäri, Mirja Lindroos, Marianne Nyström

Patent number: RE39005Abstract: In the method raw starch is treated with the amylase with the enzyme classification EC 3.21.133 below the gelatinization temperature, whereafter the maltose and the limit dextrin are recovered. The method is simple and cheap and gives rise to a maltose of high purity and to a cheap limit dextrin useable as a fat replacer in foods.Type: GrantFiled: October 13, 1994Date of Patent: March 7, 2006Assignee: Novozymes A/SInventors: Claus Christophersen, Sven Pedersen, Tommy Rex Christensen
