Abstract
The present invention relates to catalyst compositions comprising nanoparticles comprising one or more elements selected from a group 10 element, cocatalysts, catalyst promoters and organic molecules as organic stabilizing agents, in adequate porous supports. The invention also includes a particular mode of preparing the catalyst composition and the use of the catalyst in selective non-oxidative dehydrogenation of alkanes.
Claims21
A catalyst composition comprising:
- (a) a metallic nanoparticle;
- and
- (b) a porous support with a surface area:
- wherein the nanoparticle (a) is adsorbed on the surface area of the porous support;
- wherein the nanoparticle (a) comprises
- (i) one or more metallic elements of group 10 of the periodic table;
- (ii) one or more organic molecules selected from the group consisting of an organophosphorus compound and an N-heterocyclic carbene;
- and
- (iii) one or more metallic elements selected from the group consisting of tin (Sn), gallium (Ga), and indium (In).
The catalyst composition according to wherein R1, R2 and R3 are each independently selected from the group consisting of:
- (C1-C10)-alkyl, (C1-C4)-alkoxyl, (C1-C4)-alkanoyl, (C1-C4)-alkoxycarbonyl and (C1-C4)-alkanoyloxy, all of them construed as straight or branched,
- phenyl optionally substituted;
- a radical represented by —C—P(R4)(R5), wherein R4 and R5 are each independently selected from hydrogen (H) phenyl and phenyl optionally substituted;
- and
- a radical represented by —N(R6)(R7), wherein R6 and R7 are each independently selected from (C1-C10)-alkyl, (C1-C4)-alkoxyl, (C1-C4)-alkanoyl, (C1-C4)-alkoxycarbonyl and (C1-C4)-alkanoyloxy, all of them construed as straight or branched.
