Described is a method for making a composition comprising alkanes. The composition is suitable for use as a liquid transportation fuel in general, and jet fuel in particular. The method includes dehydrating a feedstock solution comprising a carbohydrate, in the presence of an acid catalyst, to yield at least one furan derivative compound, in a reaction vessel containing a biphasic reaction medium: an aqueous reaction solution and a substantially immiscible organic extraction solution. The furan derivative compound is then subjected to a self-aldol condensation reaction or a crossed-aldol condensation reaction with another carbonyl compound to yield a beta-hydroxy carbonyl compound and/or an alpha-beta unsaturated carbonyl compound. The beta-hydroxy carbonyl and/or alpha-beta unsaturated compounds are then hydrogenated to yield a saturated or partially saturated compound, followed by hydrodeoxygenation (e.g., dehydrating and hydrogenating) of the saturated or partially saturated compound to yield a composition of matter comprising alkanes.

A drier apparatus for removing water from various materials includes a drying chamber, a regenerator system, a drying fluid system, and a heating fluid recirculation system and a method for use of the apparatus. The material to be dried flows concurrently through the drier with a heating fluid that is segregated from the material but in heat transfer relationship with the material. A drying fluid flows countercurrent through the chamber so as to become heated and at least partially saturated from moisture released by the material. The drying fluid is then used to preheat recycled heating fluid which is further heated by a makeup heater. In some embodiments, the drying fluid is also recycled to the chamber after passing through a chiller.

A method and apparatus for separating arsenic from an aqueous solution containing arsenic. The method includes the steps of contacting an arsenic-containing solution with a first portion of fixing agent to remove at least a portion of the arsenic. An arsenic-laden fixing agent is separated from the solution and the partially depleted solution is contacted with a second portion of fixing agent. The fixing agent can include a high surface area insoluble compound containing one or more of cerium, lanthanum, or praseodymium. Following removal of the arsenic, the arsenic-depleted solution can be further processed to separate a recoverable metal through metal refining. The arsenic-laden fixing agent can be filtered to recover and recycle a filtrate to the solution for additional treatment, as well as using a partially saturated fixing agent to remove arsenic from fresh solution. An arsenic-containing solution can be formed from arsenic-containing solids such as contaminated soils, industrial byproducts and waste materials.
