Abstract
Mixed alcohols are produced from syngas. The syngas is provided to a catalyst in a reactor at selected temperatures and pressures. Reactive products, including mixed alcohols, are removed from the reactor. Non-reactive components are removed from the mixed alcohols of their reaction products. At least part of the non-reactive components are reintroduced in the reactor along with syngas. The non-reactive components are a solvent or a super critical fluid. The non-reactive components can be reintroduced into the reactor with reactive components such as methanol or CO2.
Claims7
A method for producing alcohols from syngas, comprising the steps of:
- a) providing a catalyst in a mixed alcohol synthesis reactor;
- b) providing syngas to the reactor at temperatures of 240-400 degrees C. and pressures of 500-2500 psi, wherein reaction products are formed, the reaction products comprising mixed alcohols;
- c) removing at least a portion of the reaction products from the reactor;
- d) removing non-reactive components from the mixed alcohols of the reaction products;
- e) reintroducing at least part of the non-reactive components into the reactor and interacting the syngas with the reintroduced non-reactive components with the catalyst in a wet mode so as to produce further reaction products that comprise mixed alcohols.
