Abstract: Systems and methods are provided for separation of particles and/or asphaltenes from heavy hydrocarbon fractions. The heavy hydrocarbon fraction can correspond to a feed including particles or a processing effluent that includes particles. If the heavy hydrocarbon fraction is mixed with lower boiling fractions, a separation can be performed to reduce or minimize the amount of hydrocarbons that are present in the heavy hydrocarbon fraction. The heavy hydrocarbon fraction can then be mixed with a sufficient amount of a separation solvent to cause a phase separation. One phase can correspond to the separation solvent plus a portion of the hydrocarbons. The other phase can correspond to hydrocarbons rejected by the separation solvent plus the particles from the heavy hydrocarbon fraction. The phases can then be separated from each other using a solids-liquid centrifugal separator.

Abstract: This application relates to renewable diesel production and to production of renewable naphtha in a renewable diesel unit. Disclosed herein is an example of a method of renewable diesel production. Examples embodiments of the method may include hydrotreating the biofeedstock by reaction with hydrogen to form a hydrotreated biofeedstock; contacting at least a portion of the hydrotreated biofeedstock with a dewaxing catalyst to produce a renewable diesel product and a renewable naphtha product; separating the renewable diesel product and the renewable naphtha product in a product splitter; and monitoring an octane number of the renewable naphtha product with an analyzer.

Abstract: Molten carbonate fuel cells (MCFCs) are operated at elevated pressure to provide increased operating voltage and/or enhanced CO2 utilization with a cathode input stream having a low CO2 content. It has been discovered that increasing the operating pressure of a molten carbonate fuel cell when using a low CO2-content cathode input stream can provide unexpectedly large increases in operating voltage while also reducing or minimizing the amount of alternative ion transport and/or enhancing CO2 utilization.

Abstract: Provided is a process capable of converting the cokes on spent catalysts in a fluid catalytic cracking (FCC) process into synthesis gas. The produced synthesis gas contains high concentrations of CO and H2 and may be utilized in many downstream applications such as syngas fermentation for alcohol production, hydrogen production and synthesis of chemical intermediates. A reducer/regenerator reactor for a fluid catalytic process comprising a chemical looping system to produce synthesis gas is also described.

Abstract: Provided herein are improved methods for estimating the flow velocity of a fluid in a vessel. Systems and methods are provided herein related to making and/or refining velocity measurements for flowing fluids, both single and multi-phase fluids, in vessels, such as pipes or conduits, utilizing contrast media property agent variations. In one aspect, this disclosure provides a method of determining a flow velocity of a fluid flow in a vessel including: providing a fluid flow having contrast media, the contrast media having a contrast media property variation; providing a detectable signal corresponding to the contrast media property variation; collecting the detectable signal at an upstream receiver to produce a first received signal; collecting the detectable signal at a downstream receiver to produce a second received signal, the downstream receiver being located downstream of the upstream receiver at a distance (L); filtering the first received signal and the second received signal through a contrast media variant filter to produce a first filtered signal and a second filtered signal; cross-correlating the first filtered signal and the second filtered signal to determine a time shift (Δt) between the first filtered signal and the second filtered signal; and estimating the velocity of the fluid flow using this relationship vflow=L/Δt.

Abstract: Systems and methods are provided for using fuel cell staging to reduce or minimize variations in current density when operating molten carbonate fuel cells with elevated CO2 utilization. The fuel cell staging can mitigate the amount of alternative ion transport that occurs when operating molten carbonate fuel cells under conditions for elevated CO2 utilization.

Abstract: Systems and methods are provided for increasing the yield of products generated during co-processing of biomass oil in a fluid catalytic cracking (FCC) system. The systems and methods can allow for increased yield by reducing or minimizing formation of carbon oxides, gas phase products, and/or coke yields during the co-processing. This can be achieved by adding a hydrogen-rich co-feed to the co-processing environment. Examples of hydrogen-rich co-feeds include high hydrogen content vacuum gas oil co-feed, high hydrogen content distillate co-feed, and/or high hydrogen content naphtha co-feed. Additionally or alternately, various types of fractions that contain a sufficient amount of hydrogen donor compounds can be used to reduce or minimize carbon oxide formation
