Abstract: The invention relates to a process for the recovery of aliphatic hydrocarbons from a liquid stream comprising aliphatic hydrocarbons, heteroatom containing organic compounds and optionally aromatic hydrocarbons, involving a) contacting said liquid stream with a stream having a pH above 7 and comprising a washing solvent, preceded and/or followed by contacting with a stream having a pH below 7 and comprising a washing solvent; b) liquid-liquid extraction of the washed stream with an extraction solvent. Further, the invention relates to a process for the recovery of aliphatic hydrocarbons from plastics comprising the above-mentioned process; and to a process for steam cracking a hydrocarbon feed comprising aliphatic hydrocarbons as recovered in one of the above-mentioned processes.

Abstract: A method for removing a contaminant from a fluid system comprises contacting the fluid system with an inversely fluidized material, for example a particulate aerogel, thereby removing at least a portion of the contaminant from the fluid system. The method can be used to remove oil or other organic materials from wastewater streams. It can be conducted in a fluidized bed, which includes nanoporous particles and a fluidizing medium, wherein the nanoporous particles have a density lower than that of the fluidizing medium.

Abstract: The invention relates to dry solid crystalline, powder, granular or amorphous forms of agave sweeteners that retain beneficial nutrients present in agave syrup and remain stable for extended periods of time. Methods for manufacture of the dry sweeteners from agave nectar are provided that employ a process comprising lyophilization. Methods for producing agave sweeteners in crystalline, powder, granular or amorphous form are provided. In addition to extended stability, manufacture using lyophilization techniques retain beneficial characteristics of the agave nectar that are lost when it is dried by other techniques.

Abstract: With the coupling of an external field and aeration (or a flow of another gas), nanoparticles can be smoothly and vigorously fluidized. A magnetic force and/or pre-treatment may be employed with the fluidizing gas and, when coupled with a fluidizing medium, provide excellent means for achieving homogenous nanofluidization. The magnetic force interacts with non-fluidizing magnetic particles and helps to break channels as well as provide enough energy to disrupt the strong interparticle forces, thereby establishing an advantageous agglomerate size distribution. Enhanced fluidization is reflected by improved performance-related attributes. The fluidized nanoparticles may be coated, surface-treated and/or surface-modified in the fluidized state. In addition, the fluidized nanoparticles may participate in a reaction, either as a reactant or a catalyst, while in the fluidized state.

Abstract: With the coupling of an external field and aeration (or a flow of another gas), nanoparticles can be smoothly and vigorously fluidized. Multiple external fields and/or pre-treatment may be employed with the fluidizing gas: sieving, magnetic assistance, vibration, acoustic/sound or rotational/centrifugal forces. Any of these forces, either alone or in combination, when coupled with a fluidizing medium, provide excellent means for achieving homogenous nanofluidization. The additional force(s) help to break channels as well as provide enough energy to disrupt the strong interparticle forces, thereby establishing an advantageous agglomerate size distribution.
