Abstract: A process is provided for purification of biogas to produce biomethane. The biogas is treated in a pressure swing adsorption unit to remove carbon dioxide and water. Other impurities including oxygen, hydrogen and carbon monoxide may be removed by an additional adsorption bed. The adsorption beds may be single stage or two-stage VPSA or PSA adsorption beds.

Abstract: A process for hydroprocessing a biorenewable feedstock is disclosed. The process comprises hydrotreating the biorenewable feed stream in a hydrotreating reactor to hydrodeoxygenate the biorenewable feed stream to provide a hydrotreated stream. A hydrocracking feed stream taken from the hydrotreated stream is hydrocracked in a hydrocracking reactor to provide a hydrocracked stream. A hydroisomerization feed stream taken from the hydrotreated stream is hydroisomerized in a hydroisomerization reactor to provide a hydroisomerized stream. The hydroisomerized stream is separated to provide a jet fuel stream and a diesel stream. The diesel stream is separated into a first recycle diesel stream and a second recycle diesel stream. The first recycle diesel stream is passed to the hydrocracking reactor and the second recycle diesel stream is passed to the hydroisomerization reactor.
