A method for detecting and analyzing olefins in petroleum by electrospray ionization mass spectrometry can include obtaining a hydrocarbon sample comprising at least about 90 wt % of saturate compounds; producing a solution comprising the hydrocarbon sample and a metal salt, the metal salt comprising a metal ion; forming olefin-metal ion complexes by electrospray ionization; and detecting the olefin-metal ion complexes using mass spectrometry.

Processes for producing alcohols from biomass are provided. The processes utilize supercritical methanol to depolymerize biomass with subsequent conversion to a mixture of alcohols. In particular the disclosure relates to continuous processes which produce high yields of alcohols through recycling gases and further employ dual reactor configurations which improve overall alcohol yields. Processes for producing higher ethers and olefins from the so-formed alcohols, through alcohol coupling and subsequent dehydration are also provided. The resulting distillate range ethers and olefins are useful as components in liquid fuels, such as diesel and jet fuel.

The present disclosure describes the use of a specific adsorbent material in a rapid cycle swing adsorption to perform dehydration of a gaseous feed stream. The adsorbent material includes a zeolite 3A that is utilized in the dehydration process to enhance recovery of hydrocarbons.
