Abstract

A process for producing microfibrillated cellulose comprises providing a slurry comprising cellulosic fibers, treating the slurry with an enzyme, mechanically treating the slurry so that the fibers are disintegrated wherein the mechanical treatment and the treatment with the enzyme is performed simultaneously in a single treatment step. In this way it is possible to produce microfibrillated cellulose (MFC) in an improved and energy efficient way. A microfibrillated cellulose is produced according to the process.

A microfibrillated cellulose is produced according to the process.Patent family as of 4.4.2022AU2010269896 AA 20120209 AU20100269896 20100623 AU2010269896 BB 20150917 AU20100269896 20100623 AU2010269912 AA 20120209 AU20100269912 20100702 AU2010269912 BB 20160114 AU20100269912 20100702 BR112012000142 A2 20201027 BR20121100142 20100702 BR112012000142 A8 20201124 BR20121100142 20100702 BR112012000142 B1 20210518 BR20121100142 20100702 BR112012000143 A2 20161101 BR20121100143 20100623 BR112012000143 B1 20190806 BR20121100143 20100623 CA2767290 AA 20110113 CA20102767290 20100702 CA2767290 C 20170124 CA20102767290 20100702 CA2767304 AA 20110113 CA20102767304 20100623 CA2767304 C 20170110 CA20102767304 20100623 CL2012000040 A1 20120713 CL20120000040 20120106 CL52943 B 20160829 CL20120000040 20120106 CL2012000053 A1 20120713 CL20120000053 20120106 CN102472014 A 20120523 CN201080030879 20100623 CN102472013 A 20120523 CN201080030882 20100702 CN102472013 B 20180406 CN201080030882 20100702 CN105755884 A 20160713 CN201610122522 20100623 DE602010035440 D1 20160922 DE201060035440T 20100623 DE602010036272 D1 20161020 DE201060036272T 20100702 EP2452014 A1 20120516 EP20100796795 20100623 EP2452014 A4 20131120 EP20100796795 20100623 EP2452014 B1 20160810 EP20100796795 20100623 EP2452013 A1 20120516 EP20100796796 20100702 EP2452013 A4 20131120 EP20100796796 20100702 EP2452013 B1 20160907 EP20100796796 20100702 IN05254KN2011 A 20160826 IN2011KN05254 20111230 IN05257KN2011 A 20160826 IN2011KN05257 20111230 JP2012533000 T2 20121220 JP20120519087T 20100623 JP5719359 B2 20150520 JP20120519087T 20100623 JP2012532952 T2 20121220 JP20120519095T 20100702 KR101715428 B1 20170310 KR20127002536 20100702 KR20120093144 A 20120822 KR20127002536 20100702 KR20120098994 A 20120906 KR20127002537 20100623 PL2452014 T3 20170428 PL20100796795T 20100623 PL2452013 T3 20170228 PL20100796796T 20100702 RU2012103990 A 20130820 RU20120103990 20100702 RU2530022 C2 20141010 RU20120103990 20100702 RU2012104000 A 20130820 RU20120104000 20100623 RU2528394 C2 20140920 RU20120104000 20100623 SE200950534 A1 20101012 SE20090050534 20090707 SE533510 C2 20101012 SE20090050534 20090707 US2012160433 AA 20120628 US20100382573 20100702 US8778134 BB 20140715 US20100382573 20100702 US2012136146 AA 20120531 US20100382662 20100623 WO11004284 A1 20110113 WO2010IB52850 20100623 WO11004300 A1 20110113 WO2010IB53043 20100702 ZA201200327 A 20120926 ZA20120000327 20120116 ZA201200329 A 20120926 ZA20120000329 20120116 Link to current patent family on right
