Abstract
The present invention relates to novel catalyst compositions and their use in a process for the catalytic conversion of ethanol to a reaction product comprising 1-butanol. The catalysts comprise Group II metal salts selected from the group consisting of oxides, carbonates, bicarbonates, hydroxides, and mixtures thereof, supported on a lanthanum-promoted oxide containing alumina.
Claims14
A process for making a reaction product comprising 1-butanol, comprising the step:
- contacting a reactant comprising ethanol with a catalyst composition at a reaction temperature and pressure sufficient to produce said reaction product, wherein said catalyst composition comprises at least one Group II metal salt supported on a lanthanum-promoted oxide containing alumina and has the following empirical formula:
- Ma[Al(1-b)Lab][Az−]c
- wherein:
- (i) M is selected from the group consisting of Mg2+, Ca2+, Sr2+, Ba2+, Ra2+, and combinations of these;
- (ii) Az− is a monovalent or divalent anion selected from the group consisting of carbonate (CO32−, wherein the charge, “z” is given by z=2), oxide (O2−, wherein z=2), hydroxide (OH−, wherein z=1), and bicarbonate (HCO3−, wherein z=1), or a mixture (Az′−xAz″−y) of these divalent and monovalent anions wherein Az′− and Az″− are different anions, with the caveat that when Az− is the mixture Az′−xAz″−y, the composite charge “z” is given by z=x(z′)+y(z″), wherein x+y=1;
- (iii) a is 0.01 to 0.4, including the endpoints of the range;
- (iv) b is 0.0011 to 0.11, including the endpoints of the range;
- and
- (v) c=(2a/z)+[3(1-b)/z]+(3b/z).
