The present disclosure relates to a composition that includes a compound having the structure R.sub.1O—(CH.sub.2O).sub.n—R.sub.2 and a cetane number between about 65 and about 100, where n is between 1 and 10, inclusively, R.sub.1 includes a first alkyl group, and R.sub.2 includes a second alkyl group.

The invention discloses novel diesel fuel compositions including a renewable diesel component, a fossil diesel component and an oxygenate component, as well as methods for manufacture and use of a combination of a renewable diesel component, and an oxygenate component for reducing particulate matter emissions.

A biodiesel fuel consisting of a dioxolane with one to three alkyl groups, a (CH.sub.2).sub.nCH.sub.3 alkyl group where n ranges from 6 to 14, and the dioxolane has a total number of carbons that is equal to or less than 24 carbons.

Provided herein are biodiesel fuel mixtures having improved properties for reducing NOx emissions as well as total particular matter emissions, CO emissions, and total hydrocarbon emissions.

A process for converting C2-5 alkanes to higher value C5-24 hydrocarbon fuels and blendstocks. The C2-5 alkanes are converted to olefins by thermal olefination, without the use of a dehydrogenation catalyst and without the use of steam. The product olefins are fed to an oligomerization reactor containing a zeolite catalyst to crack, oligomerize and cyclize the olefins to the fuel products which are then recovered. Optionally, hydrogen and methane are removed from the product olefin stream prior to oligomerization. Further optionally, C2-5 alkanes are removed from the product olefin stream prior to oligomerization.
