    摘要: Allyl alcohol, particularly from biobased sources such as glycerol, is hydroformylated to products including 4-hydroxybutyraldehyde and 4-hydroxy-2-methylpropionaldehyde by forming a homogeneous reaction mixture including allyl alcohol, a rhodium-based hydroformylation catalyst and a near critical liquefiable petroleum gas or mixture of such gases, reacting the near critical liquefiable petroleum gas (or gas mixture)-expanded allyl alcohol substrate with carbon monoxide and with hydrogen in the presence of the catalyst, and recovering substantially all of the petroleum gas or gases overhead by reducing the pressure and degassing the product mixture. Dense propane is especially useful as a single inert solvent/diluent, and substantially no other solvent/diluent is needed.

    摘要: A catalyst composition/system can include: a platinum catalyst metal (Pt) and/or rhenium catalyst metal (Re) on a first support; and a ruthenium catalyst metal (Ru) and/or rhenium catalyst metal (Re) on a second support or a platinum catalyst metal (Pt) and a ruthenium catalyst metal (Ru) and/or a rhenium catalyst metal (Re) on the same support. The Pt:Ru, Re:Pt and/or Re:Ru weight ratio can be between about 1:4 and about 4:1. The support can be alumina, carbon, silica, a zeolite, TiO2, ZrO2 or another suitable material. The first and second support can be on the same support structure or on different support structures. In one option, the first and second supports can be positioned such that the Pt and/or Re are capable of catalyzing a dehydrogenation and/or reforming reaction that produces hydrogen and the Ru and/or Re are capable of catalyzing a hydrogenolysis reaction.

    摘要: A catalyst composition can include: a support; a ruthenium catalyst (Ru) nanoparticle; and a linker linking the Ru nanoparticle to the support, wherein the linker is stable under hydrogenolysis conditions. In one aspect, the linker can include 3-aminopropyl trimethoxysilane (APTS) or derivatives thereof, such as those with amine functionality. In another aspect, the linker can include phosphotungstic acid (PTA) or other similar solid acid agents. In another aspect, the support can be selected from alumina, carbon, silica, a zeolite, TiO2, ZrO2, or another suitable material. A specific example of a support includes zeolite, such as a NaY zeolite. The Ru nanoparticle can have a size range from about 1 nm to about 25 nm, and can be obtained by reduction of Ru salts.
