    摘要: One exemplary embodiment can be a process for producing a biofuel while minimizing fossil fuel derived carbon dioxide emissions. The process can include providing a renewable feed to an ester degradation zone to produce a first stream including one or more alcohols and a second stream including one or more acids, providing the first stream to a treatment zone for removing one or more salts and to obtain a treated stream, providing the treated stream to a reforming zone to obtain an effluent including hydrogen, and providing the second stream and at least a portion of the effluent to a refining zone for producing the biofuel.

    摘要: A process is presented for the selective catalytic cracking of naphtha to light olefins. The process includes contacting a naphtha feedstream with a mixture of catalysts to reduce the amount of recycle, and especially the recycle of light paraffins. The mixture of catalysts includes a first molecular sieve made up from a small pore zeolite having a pore index between 13 and 26, and a second molecular sieve made up from an intermediate pore zeolite having a pore index between 26 and 30.

    摘要: Vapor-liquid contacting apparatuses, for example reactors and distillation columns (as well as reactive distillation apparatuses), comprising a vessel with one or more vortex contacting stages, are described. The one or more stages provide high interfacial area for the effective contacting of the different phases, in addition to the effective disengagement of these phases after contacting.
