摘要:
A hydrocarbon conversion process comprises contacting a renewable feedstock under hydroprocessing conditions with supported catalyst comprising at least one metal selected from the group consisting of Group VIII metals, Group VIB metals to form oleochemicals such as fatty alcohols, esters, and normal paraffins. Advantageously, the reaction conditions can be selected to directly convert the renewable feedstock to the desired product(s).
摘要:
The present invention relates to a new process which comprises the steps of hydrotreating, paraffin disproportionation and hydroisomerization to convert biological hydrocarbonaceous oxygenated oils comprising triglycerides into biologically-derived paraffinic jet/diesel fuels, solvents and base oils. A combination of conventional hydrogenation/dehydrogenation catalysts, such as Pt/Al2O3, and conventional olefin metathesis catalysts, such as WO3/SiO2, or inexpensive variations thereof, is generally employed in the paraffin disproportionation step.

摘要:
A reforming process using a medium pore zeolite under conditions to facilitate the conversion of C8 paraffinic compounds to para-xylene is provided. Para-xylene is produced at greater than thermodynamic equilibrium concentrations using the process.
摘要:
A process for isomerizing light paraffins using a catalyst comprising an *SFV-type zeolite and at least one Group VIII metal. It has been found that the catalyst can selectively convert C6 paraffins into the more favorable higher octane C6 isomer, namely 2,3-dimethylbutane (RON=105), over the less favorable C6 isomer, namely octane 2,2-dimethylbutane (RON=94).
摘要:
An all-silica zeolite having the IFR framework topology can be directly synthesized by preparing a reaction mixture comprising (1) an active source of silicon oxide, (2) a structure directing agent comprising a N-benzyl-1,4-diazabicyclo[2.2.2] octane cation, (3) an active source of hydroxide and (4) water and maintaining the reaction mixture under conditions sufficient to form crystals of the zeolite.
