Abstract: Systems and methods are provided for processing a feed derived from a renewable source to form oligomerized compounds corresponding to waxes, ketone waxes, and/or lubricant boiling range compounds. The oligomerized compounds derived from the renewable source can have various novel properties relative to waxes and/or lubricant boiling range compounds derived from mineral sources or derived from renewable sources in a conventional manner. The oligomerized compounds can be derived from a renewable source including fatty acids and/or fatty acid derivatives, such as glycerides (including triglycerides) and fatty amides. Optionally but preferably, at least a portion of the fatty acids and/or fatty acid derivatives can include olefinic bonds.

Abstract: Integrated methods and systems are disclosed for the production of dimethyl ether. The method may include reforming natural gas to syngas in a first reactor; contacting the syngas produced in the first reactor with a catalyst system in a second reactor to produce dimethyl ether and carbon dioxide; and supplying steam as a cofeed to at least one of the first reactor and the second reactor in an amount sufficient to achieve a Mm value of 1.4 to 1.8 or to improve the hydrocarbon or oxygenate selectivity.
