Abstract: A process for hydroprocessing a sustainable feedstock is disclosed. The process comprises hydrocracking a hydrocracking feed stream comprising greater than 90% paraffins in a hydrocracking reactor in the presence of hydrogen over a hydrocracking catalyst comprising one or more Group VIII metal and/or Group VIB to provide a hydrocracked stream. The hydrocracking reactor is operated at a temperature of about 290° C. (550° F.) to about 450° C. (842° F.) and a pressure of about 2.7 MPa (gauge) (400 psig) to about 20.7 MPa (gauge) (3000 psig). The hydrocracked stream is hydroisomerized in a hydroisomerization reactor in the presence of hydrogen over a hydroisomerization catalyst to provide a hydroisomerized stream. The hydroisomerized stream is separated to provide a jet fuel stream, a diesel stream, and an unconverted oil stream.

Abstract: A process for separating a carbon dioxide product stream from a flue gas stream is disclosed. The process comprises passing a stream of carbon dioxide and oxygen to a regenerator to generate a catalyst stream and produce a flue gas stream comprising carbon oxides, and/or nitrogen oxides, catalyst fines, oxygen, and water. Heat is transferred to a water stream from the flue gas stream in a heat recovery unit to form a cooled flue gas stream and a steam stream. Water is removed from the cooled flue gas stream in a dehydration unit to provide a dehydrated flue gas stream. The dehydrated flue gas stream is separated into an oxygen stream and a carbon dioxide product stream.

Abstract: A process is provided for production of a mesophase material that is capable of producing high performance carbon fibers. The mesophase is produced after heavy hydrocarbons have been treated to remove impurities by hydrotreating or quinoline solvent, followed by use of a toluene solvent to remove light hydrocarbons and then being upgraded by a soaker visbreaking step to produce a desirable amount of mesophase material while preventing formation of coke.
