Provided herein are methods for producing cyclic and acyclic ketones from trimerization and dimerization of alkyl ketones, including for example methyl ketones. Such cyclic and acyclic ketones may be suitable for use as fuel and lubricant precursors, and may be hydrodeoxygenated to form their corresponding cycloalkanes and alkanes. Such cycloalkanes and alkanes may be suitable for use as fuels, including jet fuels, and lubricants.

The present invention relates to a method for preparing saturated C.sub.n- and C.sub.2n-alcohols, wherein the separation of the C.sub.n-alcohols and the C.sub.2n-alcohols is effected by means of at least one two-column system or by means of at least one dividing wall column.
