Provided herein are methods for producing cyclic and acyclic ketones from trimerization and dimerization of alkyl ketones, including for example methyl ketones. Such cyclic and acyclic ketones may be suitable for use as fuel and lubricant precursors, and may be hydrodeoxygenated to form their corresponding cycloalkanes and alkanes. Such cycloalkanes and alkanes may be suitable for use as fuels, including jet fuels, and lubricants.

The present disclosure relates to a process for the hydrodeoxygenation of vegetable oils or animal fats to produce green diesel, which comprises contacting the vegetable oil or animal fat with a Nickel-Molybdenum or Cobalt-Molybdenum catalyst supported on alumina-titania or titania, respectively; in a fixed bed reactor in the presence of hydrogen. The process involves hydrocracking, hydrogenation, decarboxylation, decarbonylation, carried out in a fixed bed reactor at temperature of about 270 C. to about 360 C., pressure of about 40 kg.sub.f/cm.sup.2 to about 60 kg.sub.f/cm.sup.2, liquid hourly space velocity (LHSV) between about 0.8 h.sup.1 to about 3.0 h.sup.1, and H.sub.2/oil ratio of about 2,700 ft.sup.3/bbl to about 7,000 ft.sup.3/bbl, that allows to obtain a conversion up to 99% and up to 92.7% yield on green diesel.

Process for selective the conversion of primary C4 alcohol into propylene comprising: contacting a stream (1) containing essentially a primary C4 alcohol with at least one catalyst at a temperature ranging from 150 C. to 500 C. and at pressure ranging from 0.01 MPa to 10 MPa conditions effective to transform said primary C4 alcohol into an effluent stream (2, 5) containing essentially propylene, carbon monoxide and di-hydrogen, said transformation of primary C4 alcohol comprising at least a reaction of decarbonylation and optionally a decarboxylation reaction, said at least one catalyst comprising a support being a non-acidic i.e. having a TPD NH3 of less than 50 preferably less than 40 mol/g and optionally a non-basic catalyst i.e. having a TPD CO2 of less than 100 preferably less than 50 mol/g.

An alpha olefin synthesis process includes (i) subjecting a first normal alpha olefin to hydroformylation in the presence of carbon monoxide and hydrogen to form a first linear aldehyde, (ii) subjecting the first linear aldehyde to decarbonylative olefination to form a linear internal olefin, (iii) subjecting the linear internal olefin to isomerization-hydroformylation in the presence of carbon monoxide and hydrogen to form a second linear aldehyde, and (iv) subjecting the second linear aldehyde to hydrogenation to form a linear alcohol followed by dehydration to form a second normal alpha olefin, or subjecting the second linear aldehyde to combined hydrogenation-dehydration in a single step to form a second normal alpha olefin. Using this process, for example, ethylene can be converted to 1-hexene, and 1-butene can be converted to 1-decene.
