Method for producing ethanol and coproducing methanol
A method for producing ethanol and coproducing methanol on a catalyst in a reactor using a co-feed of a synthesis gas and acetate as a reaction raw material comprising passing a raw material gas containing an acetate and a synthesis gas through a reactor loaded with a catalyst to produce ethanol and coproduce methanol under conditions of a reaction temperature of 150-350 C., a reaction pressure of 0.1-20.0 MPa, a reaction volume hourly space velocity of 100-45000 mlg.sup.1h.sup.1, and an acetate weight hourly space velocity of 0.01-5.0 h.sup.1; and the active components of the catalyst are copper and optionally zinc and/or aluminum, which greatly facilitates the conversion of carbon monoxide to methanol, while an extremely high activity of acetate hydrogenation is maintained.
CHROMIUM- AND NICKEL-FREE HYDROGENATION OF HYDROFORMYLATION MIXTURES
The invention is concerned with catalysts for heterogeneous hydrogenation of oxo process aldehydes. The problem addressed by the invention is that of developing a catalyst containing neither chromium nor nickel. In addition, it is to enable the economically viable hydrogenation of aldehyde mixtures originating from industrial oxo processes on the industrial scale. For this purpose, the catalyst should not be reliant on costly precious metals such as Ru, Pd or Pt. This problem was solved by omitting the chromium and nickel in the preparation of a conventional Cu/Ni/Cr system, such that a catalyst wherein only copper occurs as hydrogenation-active component on the support material thereof, and not chromium or nickel, is obtained. What is surprising here is that a functioning catalyst for the purpose intended still arises at all even though two of three hydrogenation-active metals are omitted. However, this requires as necessary conditions that support material used is silicon dioxide and that the content of Cu and SiO.sub.2 in the active catalyst is set accurately within very tight limits.
Processes to create multiple value streams from biomass sources
Use of diverse biomass feedstock in a process for the recovery of target C5 and C6 alditols and target glycols via staged hydrogenation and hydrogenolysis processes is disclosed. Particular alditols of interest include, but are not limited to, xylitol and sorbitol. Various embodiments of the present invention synergistically improve overall recovery of target alditols and/or glycols from a mixed C5/C6 sugar stream without needlessly driving total recovery of the individual target alditols and/or glycols. The result is a highly efficient, low complexity process having enhanced production flexibility, reduced waste and greater overall yield than conventional processes directed to alditol or glycol production.
