Title: Synergistic interaction between oxides of copper and iron for production of fatty alcohols from fatty acids

Abstract

In this study, the selective hydrogenation of fatty acids to fatty alcohols can be achieved under moderate conditions (180 °C, 30 bar H₂) by simultaneously supporting copper and iron oxides on mesoporous silica nanoparticles. The activity of the cosupported oxides is significantly higher than that of each supported metal oxide and of a physical mixture of both individually supported metal oxides. A strong interaction between both metal oxides is evident from dispersion, XRD, TPR, and acetic acid TPD measurements, which is likely responsible for the synergistic behavior of the catalyst. Copper oxide is reduced in situ to its metallic form and thereby activates hydrogen.

Elucidating the Copper–Hägg Iron Carbide Synergistic Interactions for Selective CO Hydrogenation to Higher Alcohols

Journal Article Lu, Yongwu ; Zhang, Riguang ; Cao, Baobao ; ... - ACS Catalysis

CO hydrogenation to higher alcohols (C₂+OH) provides a promising route to convert coal, natural gas, shale gas, and biomass feedstocks into value-added chemicals and transportation fuels. However, the development of nonprecious metal catalysts with satisfactory activity and well-defined selectivity toward C₂+OH remains challenging and impedes the commercialization of this process. Here, we show that the synergistic geometric and electronic interactions dictate the activity of Cu-0-chi-Fe₅C₂ binary catalysts for selective CO hydrogenation to C₂+OH, outperforming silica-supported precious Rh-based catalysts, by using a combination of experimental evidence from bulk, surface-sensitive, and imaging techniques collected on real and high-performance Cu-Fe binary catalytic systemsmore »« less

Synthesis of alcohols from syngas and alcohol chain growth over copper-cobalt based catalysts

Conference Chu, Wei ; Xiong, Guoxing

The alcohols synthesis from syngas was studied under pressure (6.0 MPa). The higher alcohols formation increased with the cobalt content, caused probably by the augmentation of the number of the Co-Cu bisites, and the higher hydrocarbons augmented simultaneously, explained by common reactional intermediates. The TPR, CO Chemisorption, XRD and TPD experiments were performed for the catalyst characterizations. There were some strong interactions between cobalt and copper, and the cobalt addition onto CuLaZr catalyst may have three important effects on alcohol chain growth: an increase of the formation of hydrocarbonated species, an augmentation of the CO insertion property, and a modificationmore »« less
Multitasking mesoporous nanomaterials for biorefinery applications

Thesis/Dissertation Kandel, Kapil

Mesoporous silica nanoparticles (MSNs) have attracted great interest for last two decades due to their unique and advantageous structural properties, such as high surface area, pore volume, stable mesostructure, tunable pore size and controllable particle morphology. The robust silica framework provides sites for organic modifications, making MSNs ideal platforms for adsorbents and supported organocatalysts. In addition, the pores of MSNs provide cavities/ channels for incorporation of metal and metal oxide nanoparticle catalysts. These supported metal nanoparticle catalysts benefit from confined local environments to enhance their activity and selectivity for various reactions. Biomass is considered as a sustainable feedstock with potentialmore »« less

Combustion of CO and toluene; characterisation of copper oxide supported on titania and activity comparisons with supported cobalt, iron, and manganese oxide

Journal Article Larsson, P O ; Andersson, A ; Wallenberg, L R ; ... - Journal of Catalysis

Titania-supported copper oxide catalyst have been prepared with loadings in the range from 1/3 to 5 theoretical layers and have been tested for the combustion of CO and toluene. Characterisation with XRD, electron microscopy, EDX, TPR, Raman, and XPS gives details about the structure of copper oxide on titania. The results show that dispersed CuO{sub x} is formed up to a loading of about one theoretical layer. TPR indicates the formation of two types of dispersed species, which possibly are isolated and polymeric, respectively. XPS data show that the dispersed copper is Cu{sup 2+}. The dispersed species have high catalyticmore »« less

Enzymatic esterification of saturated fatty acids with aliphatic alcohols as an alternative method of a low-temperature synthesis of esters

Journal Article Perminova, L. V., E-mail: perminova@catalysis.ru ; Kovalenko, G. A. ; Chukanov, N. V. ; ... - Russian Chemical Bulletin

low-temperature synthesis of saturated fatty acid esters with aliphatic alcohols by enzymatic esterification in the presence of heterogeneous biоcatalysts was suggested. The biоcatalysts were prepared by immobilization of recombinant rPichia/lip lipase on mesoporous silica. A comparison of the reaction rates was used to make up a matrix of biоcatalyst activities and determine a pair of acid/alcohol substrates, for which a maximum esterification rate was observed. A high activity of biоcatalysts was observed in the esterification of fatty acids with seven or more carbon atoms in the molecule. The rate of esterification of fatty acids with primary alcohols (n-C{sub 3}—C{sub 16}more »« less
