Abstract: The present disclosure refers to systems and methods for the production, storage, and transportation of hydrogen. In a representative embodiment a reactor system comprises a fluidized bed combustor configured for reduced metal oxide oxidation and heat generation without significant greenhouse gas emission and/or with readily capturable emissions. The reactor system also comprises a liquid organic hydrogen carrier dehydrogenation reactor. The fluidized bed combustor is operatively coupled to the liquid organic hydrogen carrier dehydrogenation reactor. Advantageously, at least a portion of heat generated by the fluidized bed combustor may be transferred to the liquid organic hydrogen carrier dehydrogenation reactor. In this manner hydrogen production and transportation is both energy efficient, low carbon intensity and cost-effective.

Abstract: The present disclosure refers in one embodiment to processes for making and transporting clean hydrogen fuel. The processes may involve hydrotreating, hydrocracking, or both hydrotreating and hydrocracking an aromatic feedstock under conditions to obtain a liquid hydrocarbon fuel. The liquid hydrocarbon fuel is hydrogenated to obtain a hydrogen-rich fuel that is transported to a dehydrogenation facility that may also be at or near a hydrogen station. The hydrogen-rich fuel is used to obtain hydrogen and a second liquid hydrocarbon fuel.

Abstract: Provided is an improved hydroprocessing process allowing one to realize superior isoselectivity. The process comprises contacting a feed comprised of normal hydrocarbons under hydroprocessing conditions with a catalyst comprising delaminated SSZ-70. The delaminated SSZ-70 has been found to provide unexpected improvements in the catalysis of hydroprocessing hydrocarbons. Delaminated SSZ-70 offers a zeolite layer with a single unit cell of thickness in one dimension, allowing an elimination of mass transfer in comparison with non-delaminated SSZ-70.

Abstract: This disclosure pertains to a supported noble metal catalyst containing noble metal component and a sulfur-containing component being supported on a non-noble metal doped inorganic oxide carrier and uses thereof. The catalyst may be used for the hydrogenation of an aromatic compound. The present disclosure further relates to a process for the partial or complete dehydrogenation of perhydrogenated or partially hydrogenated cyclic hydrocarbons to produce hydrogen.

Abstract: Provided is a hydrocracking process with a recycle loop for converting a petroleum feed to lower boiling products, which process comprises reacting a stream over a non-zeolite noble metal catalyst at a temperature of about 650° F. (343° C.) or less in a reactor positioned in the recycle loop of the hydrocracking reactor.

Abstract: An integrated system for monitoring a chemical concentration in an ionic liquid, comprising: a. an online FTIR instrument with an ATR window; b. a sample conditioning station that removes light hydrocarbons and produces a degassed ionic liquid that is analyzed by FTIR; and c. a solvent flushing system that flows solvent across the ATR window. Also, a process for monitoring the chemical concentration, comprising: a. degassing the ionic liquid in the sample conditioning station; b. passing the degassed ionic liquid over an ATR window; c. periodically redirecting a flow of the degassed ionic liquid via a bypass line or an on-off valve that isolates the ATR window from the process unit that elutes the ionic liquid; and d. flowing a solvent and a purging gas over the ATR window during the periodically redirecting step c); and e. resuming the passing of the degassed ionic liquid over the ATR window.
