Abstract: A transport system for carrying a proppant, the system comprising a loading tower, a first transfer tower, a second transfer tower and an unloading tower. The loading tower is located proximate a loading area while the unloading tower is located proximate an unloading area. The system also includes a first transfer tower and a second transfer tower. A first aerial cable conveys a transfer container from the loading tower to the first transfer tower, while a second aerial cable conveys the transfer container from the second transfer tower to the unloading tower. The transfer container is configured to be suspended from the first and second aerial cables en route from the loading tower to the unloading area. Sand or supplies from the transfer container is received at the unloading area for use in a wellbore operation. Methods of transporting sand for use in wellbore fracturing operations are also provided.

Abstract: Provided herein are methods and systems of making a high quality isoparaffinic base stock which include contacting an adsorbent material with a hydrocarbon feedstock and a solvent and separating at least some of the one or more high VI components from the hydrocarbon feedstock to produce a first fraction base stock having a first fraction base stock viscosity index. The adsorbent material is desorbed with a second solvent to produce a second fraction base stock having a second fraction base stock viscosity index. In these methods, the first fraction base stock viscosity index is less than the hydrocarbon feedstock viscosity index and the second fraction base stock viscosity index is greater than the hydrocarbon feedstock viscosity index.

Abstract: Systems and methods are provided for production of renewable jet fuel and/or jet fuel blending component fractions using a single stage reaction system. Although only a single separation stage is used, the systems and methods can reduce or minimize the volume of feedstock that is exposed to hydrocracking conditions while still producing a jet boiling range fraction having beneficial cold flow properties.

Abstract: Systems and methods are provided for using size-reversing materials in vessels where direct heating is used to at least partially provide heat for reforming reactions under cyclic reforming conditions. An example of a size-reversing material is the combination of NiO and Al2O3. It has been discovered that size-reversing materials can undergo a phase transition that can assist with re-dispersion of metal at elevated temperatures. This can assist with maintaining catalytic activity for reforming over longer time periods in the presence of cyclic reforming conditions.
