Abstract
Disclosed are novel supported nanoparticle compositions, precursors, processes for making supported nanoparticle compositions, processes for making catalyst compositions, and processes for converting syngas. The catalyst composition can comprise nanoparticles comprising metal oxide(s), such as manganese cobalt oxide. This disclosure is particularly useful for converting syngas via the Fischer-Tropsch reactions to make olefins and/or alcohols.
Claims25
A supported nanoparticle composition comprising:
- a support;
- and
- a plurality of nanoparticles on the support, wherein:
- each nanoparticle comprises a kernel, the kernels have an average particle size from 4 to 100 nm and a particle size distribution of no greater than 20%;
- the kernels comprise oxygen, a metal element M1, optionally sulfur, optionally phosphorus, an optional metal element M2, and optionally a third metal element M3, where:
- M1 is selected from Mn, Fe, Co, and combination of two or more thereof;
- M2 is selected from Ni, Zn, Cu, Mo, W, Ag, and combinations thereof;
- M3 is selected from Y, Sc, alkaline metals, the lanthanides, group 13, 14, or 15 elements, and combinations thereof;
- and
- the molar ratios of M2, M3, S, and P, if any, to M1 is r1, r2, r3, and r4, respectively, 0≤r1≤2, 0≤r2≤2, 0≤r3≤5, and 0≤r4≤5.
A process for making the supported nanoparticle composition, comprising:
- (I) providing a nanoparticle dispersion comprising a liquid medium and a plurality of nanoparticles distributed therein, wherein each nanoparticle comprises a kernel, the kernels have an average particle size from 4 to 100 nm and a particle size distribution of 20% or less;
- the kernels comprise oxygen, a metal element M1, optionally sulfur, optionally phosphorus, optionally a second metal element M2, and optionally a third metal element M3, where:
- M1 is selected from Mn, Fe, Co, or a combination of two or more thereof;
- M2 is selected from Ni, Zn, Cu, Mo, W, Ag, and combinations thereof;
- M3 is selected from Y, Sc, alkaline metals, the lanthanides, group 13, 14, and 15 elements, and combinations thereof;
- and
- the molar ratios of M2, M3, S, and P, if any, to M1 is r1, r2, r3, and r4, respectively, 0≤r1≤2, 0≤r2≤2, 0≤r3≤5, and 0≤r4≤5;
- and
- (II) disposing a quantity of the nanoparticle dispersion on a support to obtain a supported nanoparticle composition.
