摘要:
Tissue paper products comprising a two component chemical softener composition and binder materials, either permanent or temporary wet strength binders, and/or dry strength binders are disclosed. The two component chemical softening composition comprises a quaternary ammonium compound and a polysiloxane compound. Preferred quaternary ammonium compounds include dialkyl dimethyl ammonium salts such as di(hydrogenated)tallow dimethyl ammonium chloride and/or di(hydrogenated)tallow dimethyl ammonium methyl sulfate. Preferred polysiloxanes include amino-functional polydimethyl polysiloxanes wherein less than about 10 mole percent of the side chains on the polymer contain an amino-functional group.
摘要:
An integrated plant generates syngas from biomass, where the integrated plant includes a Thermo Mechanical Pulping (TMP) process, a biomass gasifier, a methanol synthesis process, and a liquid fuel generation process. Biomass is received as a feedstock in the TMP process. The biomass is pre-treated in the TMP process for subsequent supply to the biomass gasifier by using a combination of heat, pressure, moisture, and mechanical agitation that are applied to the biomass to make the biomass into a pulp form. The TMP process breaks down a bulk structure of the received biomass, at least in part, by applying steam to degrade bonds between lignin and hemi-cellulose from cellulose fibers of the biomass. Next, the broken down particles of the biomass are reacted in a biomass gasification reaction at a temperature of greater than 700 degrees C. to create syngas components, which are fed to a methanol synthesis process.

Tissue paper products comprising a two component chemical softener composition and binder materials, either permanent or temporary wet strength binders, and/or dry strength binders are disclosed. The two component chemical softening composition comprises an ester-functional ammonium compound and a polysiloxane compound. Preferred ester-functional ammonium compounds include diester dialkyl dimethyl ammonium salts such as diester di(touch hardened)tallow dimethyl ammonium chloride and/or di(hydrogenated)tallow dimethyl ammonium chloride. Preferred polysiloxanes include amino-functional polydimethyl polysiloxanes wherein less than about 10 mole percent of the side chains on the polymer contain an amino-functional group.

摘要:
A biomass composition of matter to be used in a torrefaction process or a biomass gasification reaction is described. The biomass in a particle form is created in a pretreatment step that occurs prior to the torrefaction process or the biomass gasification reaction. A bulk structure of the biomass is 1) stripped apart to at least partially separate an outer layer of lignin in the biomass from the cellulose fibers, 2) internally blown apart to create fragments of the fiber bundle, and 3) any combination of the two in the pretreatment step. The biomass in particle form has a length to thickness aspect ratio on average of less than 300 to 1, a thickness on average of less than 100 microns thick and a length on average of less than 3000 microns.
