Abstract:
A catalyst and process for the deoxygenation and conversion of bio-derived feedstocks. The catalyst comprises a silica-alumina support having specifically defined physical properties and a molybdenum component but a material absence of nickel. The process involves the processing of a bio-derived feedstock having an oxygen content to yield a conversion product having an exceptional distillation profile and physical properties and a substantially reduced oxygen content.

Abstract:
Form liquid product stream that has a C13 to C20 hydrocarbon content of less than 5.0 wt % based upon a total weight of the liquid product stream via a process that includes contacting synthesis gas with a sulfurized Zeolite Socony Mobil-5 catalyst. The sulfurized Zeolite Socony Mobil-5 catalyst can include ZSM-5, cobalt, an alkali metal, sulfur, and a reduction promoter.
Abstract:
A catalyst for the epoxidation of an olefin comprising a carrier and, deposited on the carrier, silver, a rhenium promoter, a first co-promoter, and a second co-promoter; wherein the molar ratio of the first co-promoter to the second co-promoter is greater than 1; the first co-promoter is selected from sulfur, phosphorus, boron, and mixtures thereof; and the second co-promoter is selected from tungsten, molybdenum, chromium, and mixtures thereof, and wherein and wherein the catalyst further comprises deposited on the carrier a potassium promoter in a quantity of at least 0.5 mmole/kg, in particular at least 1.5 mmole/kg, relative to the weight of the catalyst; a process for preparing the catalyst; a process for preparing an olefin oxide by reacting a feed comprising an olefin and oxygen in the presence of the catalyst; and a process for preparing a 1,2-diol, a 1,2-diol ether, a 1,2-carbonate, or an alkanolamine.

Abstract:
In an oxychlorination process of the type where ethylene is converted to 1,2-dichloroethane in the presence of a supported copper catalyst, the improvement comprising: the use of a supported catalyst prepared by (i) impregnating, within a first step, an alumina support with a first aqueous solution including copper, to thereby form a first catalyst component; and (ii) impregnating, within a subsequent step, the first catalyst component with a second aqueous solution including copper and alkaline earth metal, to thereby form the supported catalyst.
Abstract:
This invention provides a process for producing a fluoroolefin comprising reacting, in a vapor phase, a fluorinating agent and a chlorine-containing alkene or a chlorine-containing alkane in the presence of at least one catalyst selected from the group consisting of chromium oxide containing a Group 5 element and fluorinated chromium oxide containing a Group 5 element. According to the process of the present invention, the target fluoroolefin can be obtained with high starting material conversion and good selectivity.
