20120100367 | CELLULOSE MICROFIBRILS AS AIR RELEASE AGENT - The present invention relates to the use of microfibrillated cellulose (MFC) as an air release agent in viscous compositions that are subjected to a hardening step. The air release agent according to the invention is added prior to or during said hardening step, in particular drying, cooling and/or curing process. The present invention also relates to such viscous compositions in an article comprising the MFC as further specified in the description as an air release agent. | 04-26-2012 |
20120090192 | METHOD FOR DRYING MICROFIBRILLATED CELLULOSE - The invention relates to a method for drying microfibrillated cellulose, comprising at least the following steps: (i) applying a composition comprising microfibrillated cellulose and a liquid onto a cold surface; (H) removing the frozen composition formed in step (i) from said surface to form frozen particles; (iii) optionally increasing the size of the frozen particles formed in step (ii); (iv) drying the frozen particles formed in step (iii) comprising: subjecting said particles to a cold moving gas thus removing liquid by means comprising sublimation and optionally (v) isolating the microfibrillated cellulose formed in step (iv). The invention also relates to a device for carrying out the method of the invention. | 04-19-2012 |
20110250638 | LIGNOCELLULOSIC BIOMASS CONVERSION - The present invention relates to a process for the production of second generation biofuels and/or sugar based chemicals—for example ethanol, butanol etc—and/or materials—for example plastics, single cell proteins etc.—together with sulfonated lignin from lignocellulosic biomass, in particular from lignocellulosic biomass comprising, among others, annual plants, agricultural waste, or wood. In particular, the present invention relates to a process for the production of sugar based chemicals, biofuels or materials together with sulfonated lignin from lignocellulosic biomass comprising the pretreatment of a lignocellulosic biomass in a sulfite cooking step. | 10-13-2011 |
20110006264 | CORROSION INHIBITOR - It has surprisingly been discovered that simple diols and triols work as corrosion inhibitors in concentrated organic and inorganic acids, e.g. used as additives in metallic equipment in factories and plants. These corrosion inhibitors are cheap and readily available in large quantities. The diol and triol also reduces evaporation of the acid, and thus improves the working environment. | 01-13-2011 |
