摘要： The creation of novel halloysite-based compositions is disclosed. In one embodiment, the hollow clay nanotubes of halloysite are loaded with nanoscale zerovalent iron particles. The resulting composition provides an effective manner of remediating chlorinated hydrocarbons. In another embodiment, the hollow clay nanotubes of halloysite are imbibed with dispersants such as DOSS and Tween 80 surfactants. The resulting composition stabilizes oil-in-water emulsions and subsequently releases the surfactants, thereby reducing interfacial tension significantly, which allows much smaller droplets to form and thus provides for more effective oil remediation.

摘要： The present invention relates to a method for conversion of biomass to biochar in subcritical water at 230-350° C. and 500-3000 psi. Under subcritical water conditions, biomass readily converts into biochar, biocrude, and some gases. In this invention, yield of biochar is significantly improved by recycling of biocrude. The process can produce hydrophobic biochar that has at least 70 wt % (dry basis) carbon as opposed to ˜25 wt % carbon in hydrophilic biomass, and has a heating value of about 29 MJ/kg (HHV-dry basis) which is comparable to good quality coals. More than 90% energy of biomass is retained in the biochar. The invention provides an effective means to convert biomass into a high energy density fuel for use in a variety of applications.

摘要： It has been now surprisingly discovered after extensive research that 2-halo-4,6-bisaryl-1,3,5-triazine can be prepared with unprecedented selectivity, efficiency, mild conditions, and in high yield by the reaction of cyanuric halide with aromatics in the presence of at least one Lewis acid and at least one reaction promoter. This reaction is also unprecedently general as a variety of aromatics can be used to produce a wide selection of 2-halo-4,6-bisaryl-1,3,5-triazines. The novel approach includes the use of the reaction promoters in combination with at least one Lewis acid under certain reaction conditions to promote the formation of 2-halo-4,6-bisaryl-1,3,5-triazine compounds from cyanuric halide. Preferably, the Lewis acids and reaction promoters are combined to form a complex. 2-Halo-4,6-bisaryl-1,3,5-triazines are key intermediates for making 2-(2-oxyaryl)-4,6-bisaryl-1,3,5-triazine class of UV absorbers.
