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 SiOin the active catalyst is set accurately within very tight limits.

The invention relates to a porous heterogeneous catalyst. In order to prepare a catalyst which catalyzes with a relatively high selectivity the hydrogenation of individual unsaturated bonds of polyunsaturated compounds it is proposed that the inner surface of the catalysts is coated with an ionic liquid.

This invention relates to biomass pyrolysis through the use of a hot liquid refinery feedstock as a heat transfer medium, preferably a vacuum gas oil feedstock.

This invention relates to a process for removing polarizable impurities from hydrocarbons and mixtures of hydrocarbons using ionic liquids as an extraction medium. By way of extraction, the degree of contamination of the hydrocarbon or mixture of hydrocarbons is reduced to a low or very low level. The specific ionic liquids are compounds of the Formula 1, which are organic salts that are liquid or can be melted to form a liquid and that can form at least a biphasic mixture with a hydrocarbon. The process is suitable for purifying a wide range of hydrocarbons under a wide range of process conditions.
