    Abstract: One exemplary embodiment can be a process for producing a renewable hydrocarbon fuel. The process can include providing a feed including a lignocellulosic material to a pyrolysis zone to produce a stream including a pyrolysis oil, providing the pyrolysis oil stream to a refining zone producing a refined stream, providing at least a portion of the refined stream to a reforming zone producing a stream including hydrogen, providing at least a portion of the hydrogen stream to the refining zone; and recovering the renewable hydrocarbon fuel from the refined stream.

    Abstract: The average propylene selectivity per on-stream cycle of an alcoholic oxygenate to propylene (OTP) process using one or more fixed beds of a dual-function oxygenate conversion catalyst is substantially enhanced by the use of a feed pretreatment step involving a catalytic etherification reaction, by switching to moving bed reactor technology in the olefin synthesis portion of the OTP flow scheme in lieu of fixed bed technology and by the selection of a catalyst on-stream cycle time of 300 hours or less. These provisions hold the build-up of coke deposits to a level which does not substantially degrade catalyst activity, oxygenate conversion and propylene selectivity, thereby enabling maintenance of propylene average cycle yield at essentially start-of-cycle levels. The propylene average cycle yield improvement of the present invention over that achieved by the fixed bed system of the prior art is of the order of about 1.5 to 5.5 wt % or more.

    Abstract: The average cycle propylene selectivity of an oxygenate to propylene (OTP) process using one or more fixed or moving beds of a dual-function oxygenate conversion catalyst with recycle of one or more C4+ olefin-rich fractions is substantially enhanced by the use of selective hydrotreating technology on these C4+ olefin-rich recycle streams to substantially eliminate detrimental coke precursors such as dienes and acetylenic hydrocarbons. This hydrotreating step helps hold the build-up of detrimental coke deposits on the catalyst to a level which does not substantially degrade dual-function catalyst activity, oxygenate conversion and propylene selectivity, thereby enabling a substantial improvement in propylene average cycle yield. The propylene average cycle yield improvement enabled by the present invention over the prior art system but without the use of the hydrotreating step on the C4+ olefin-rich recycle stream is of the order of 1.5 to 5.5 wt-% or more.

    Abstract: A process for generating at least one polyol from a feedstock comprising saccharide is performed in a continuous or batch manner using a catalyst system. The process involves, contacting hydrogen, water, and a feedstock comprising saccharide, with a catalyst system to generate an effluent stream comprising at least one polyol and recovering the polyol from the effluent stream. The catalyst system comprises at least one metal component with an oxidation state greater than or equal to 2+.
