20090077867 | Production of Diesel Fuel from Renewable Feedstocks with Reduced Hydrogen Consumption - A process has been developed for producing diesel boiling range fuel from renewable feedstocks such as plant and animal fats and oils. The process involves treating a renewable feedstock by hydrogenating and deoxygenating to provide a hydrocarbon fraction useful as a diesel boiling range fuel. Water is added to the deoxygenation reaction to drive carbon monoxide and water to react to form hydrogen and carbon dioxide. The hydrogen is then consumed by the reactions. If desired, the hydrocarbon fraction can be isomerized to improve cold flow properties. | 03-26-2009 |
20090193709 | Production of Diesel Fuel from Biorenewable Feedstocks with Lower Hydrogen Consumption - A process has been developed for producing diesel boiling range fuel from renewable feedstocks such as plant and animal fats and oils. The process involves treating a renewable feedstock by hydrogenating and deoxygenating i.e. decarboxylating, decarbonylating, and hydrodeoxygenating to provide a hydrocarbon fraction useful as a diesel boiling range fuel. A sulfur containing component is added to drive the conversion preferentially through carbonylation and carbonylation with reduced hydrodeoxygenation. If desired, the hydrocarbon fraction can be isomerized to improve cold flow properties. | 08-06-2009 |
20090321311 | PRODUCTION OF DIESEL FUEL FROM RENEWABLE FEEDSTOCKS CONTAINING PHOSPHORUS - A process has been developed for producing diesel fuel from renewable feedstocks such as plant oils, animal oils and greases. The process involves treating a renewable feedstock by hydrogenating and deoxygenating to provide a diesel boiling range fuel hydrocarbon product. If desired, the hydrocarbon product can be isomerized to improve cold flow properties. A portion of the hydrocarbon product is recycled to the treatment zone to increase the hydrogen solubility of the reaction mixture. The renewable feedstock comprises from about 1 to about 20 wt. ppm phosphorus measured as elemental phosphorus. | 12-31-2009 |
20100160698 | PROCESS FOR THE PRODUCTION OF HYDROCARBONS, USEFUL FOR MOTOR VEHICLES, FROM MIXTURES OF A BIOLOGICAL ORIGIN - The present invention describes a process for producing, in a single step, hydrocarbon fractions useful as diesel fuel or as a component of diesel fuel, from a mixture of a biological origin containing esters of fatty acids, and possibly also containing aliquots of free fatty acids. The process comprises the contemporaneous hydrodeoxygenation and hydroisomerization of the mixture of a biological origin, with the formation of linear and branched paraffins. The process is carried out in the presence of a catalytic composition comprising:
