20090062590 | Process for separating a heavy oil feedstream into improved products - This invention relates to a process for separating a heavy hydrocarbon stream to produce at least one permeate product stream and at least one retentate product stream. The process utilizes an ultrafiltration process to designed to maximize the quality of the permeate and retenate product streams as well as process embodiments which improve permeate production quantities as well as improve the quality of the product streams obtained by the separations process. In preferred embodiments, the process includes configuration and operational parameters to maximize permeate yield and selectivity. | 03-05-2009 |
20110111992 | LUBRICATING FLUIDS - The invention concerns a fully formulated lubricating fluid or grease comprising an additive package and a major amount of base oil, the improvement comprising the substantial absence of low molecular weight primary, secondary, tertiary, cyclic aliphatic mono or polyamines of 30 carbons or less and the absence of the corresponding acid phosphate amine salts in said fully formulated lubricating fluid. | 05-12-2011 |
20120096762 | PHOSPHORUS RECOVERY FROM HYDROTHERMAL TREATMENT OF BIOMASS - Biomass based feeds are processed under hydrothermal treatment conditions to produce a hydrocarbon liquid product and a solids portion. The solids portion can contain a portion of the phosphorus from the biomass feed. The amount of phosphorus in the solids portion can be increased for some biomass feeds by adding a multivalent metal to the feed. The phosphorus from the solids portion can be recycled for further use, such as for growth of additional biomass. | 04-26-2012 |
20120101319 | CATALYTIC HYDROTHERMAL TREATMENT OF BIOMASS - Biomass based feeds are processed under hydrothermal treatment conditions, e.g., to produce a hydrocarbon liquid product and a solids portion. The hydrothermal treatment is performed in the presence of a dissolved catalyst or catalyst precursor. The presence of the dissolved catalyst or catalyst precursor can modify the nature of the hydrocarbon products produced from the hydrothermal treatment. | 04-26-2012 |
20120130141 | CATALYST RECOVERY IN HYDROTHERMAL TREATMENT OF BIOMASS - Biomass based feeds are processed under hydrothermal treatment conditions to produce a hydrocarbon liquid product and a solids portion. The hydrothermal treatment is performed in the presence of catalyst particles. The presence of the heterogeneous catalyst can modify the nature of the hydrocarbon products produced from the hydrothermal treatment. After the hydrothermal treatment, the catalyst particles can be separated from the algae-based solids, to allow for recycle of the catalyst particles. | 05-24-2012 |
20140163285 | CATALYTIC CRACKING PROCESS FOR BIOFEEDS - A process of catalytically cracking a feedstock based on a biocomponent contacts the feedstock with a catalytic cracking catalyst comprising a basic metal oxide on a porous oxide support at an elevated cracking temperature to eliminate oxygen from the biocomponent to form cracked hydrocarbon residues. The basic metal oxide of the cracking catalyst is preferably a metal oxide of Group 2 of the Periodic Table (IUPAC) such as calcium or magnesium on a support comprised of a non-acidic form of alumina such as gibbsite or boehmite. Preferred feedstocks are those based on triglycerides, especially vegetable oils, animal fats and algae oils. | 06-12-2014 |
20140262944 | PRODUCTION OF BASE OILS FROM PETROLATUM - Methods are provided for producing lubricant base oils from petrolatum. After solvent dewaxing of a brightstock raffinate to form a brightstock base oil, petrolatum is generated as a side product. The petrolatum can be hydroprocessed to form base oils in high yield. The base oils formed from hydroprocessing of petrolatum have an unexpected pour point relationship. For a typical lubricant oil feedstock, the pour point of the base oils generated from the feedstock increases with the viscosity of the base oil. By contrast, lubricant base oils formed from hydroprocessing of petrolatum have a relatively flat pour point relationship, and some of the higher viscosity base oils unexpectedly have lower pour points than lower viscosity base oils generated from the same petrolatum feed. The base oils from petrolatum are also unusual in yielding both high viscosity and high viscosity index and can be generated while maintaining a high yield. | 09-18-2014 |
