Compositions and methods for forming hydrocarbon products from triglycerides are disclosed. In one aspect, the methods involve the thermal decomposition of fatty acids, which can be derived from the hydrolysis of triglycerides. The thermal decomposition products can be combined with low molecular weight olefins, such as Fischer-Tropsch synthesis products, and subjected to molecular averaging reactions. Alternatively, the products can be subjected to hydrocracking reactions, isomerization reactions, and the like. The products can be isolated in the gasoline, jet and/or diesel fuel ranges. Thus, vegetable oils and/or animal fats can be converted using water, catalysts, and heat, into conventional products in the gasoline, jet and/or diesel fuel ranges. These products are virtually indistinguishable from those derived from their petroleum-based analogs, except that they can have virtually no aromatic, sulfur or nitrogen content, they are derived, in whole or in part, from renewable resources, and can also be derived from domestically available coal and/or natural gas.

A catalyst for purifying exhaust gases of a diesel engine. The catalyst contains two functional layers superimposed on an inert supporting body, whereby the first layer, which is situated directly on the supporting body, has a nitrogen oxide storage function and the second layer, which is in direct contact with the exhaust gas, has a catalytic function. The second functional layer additionally has a hydrocarbon-storage function and its catalytic function is provided by catalytically active noble metals of the platinum group which are deposited in highly dispersed form on finely divided, acidic carrier materials. Nitrogen oxides in the oxygen-rich exhaust gas of a diesel engine can be converted with optimal utilization of the reductive constituents contained in the exhaust gas. For this purpose, no reducing agents going beyond the reductive components (carbon monoxide and hydrocarbons) which are contained as a consequence of incomplete combustion need to be added to the exhaust gas. Nevertheless, rates of conversion in respect of the nitrogen oxides are obtained, averaged over practical driving cycles, which lie distinctly above the rates of conversion of conventional reduction catalysts.

This invention provides a means of loading, processing and conditioning raw production gas, production of CGL, storage, transport, and delivery of pipeline quality natural gas or fractionated products to market. The CGL transport vessel utilizes a pipe based containment system to hold more densely packed constituents of natural gas held within a light hydrocarbon solvent than it is possible to attain for natural gas alone under such conditions. The containment system is supported by process systems for loading and transporting the natural gas as a liquid and unloading the CGL from the containment system and then offloading it in the gaseous state. The system can also be utilized for the selective storage and transport of NGLs to provide a total service package for the movement of natural gas and associated gas production. The mode of storage is suited for both marine and land transportation and configured in modular form to suit a particular application and/or scale of operation.

A method for removing sludge from a petroleum storage tank is based on a two-step approach utilizing solvent extraction to dissolve organic components of the sludge followed by water wash to remove inorganic materials. Sludges contain both organic-based solids (e.g., waxes and asphaltenes) as well as inorganic-based solids (known to exist as salts such as chlorides, carbonates, and oxides). The organic components of the sludge are dissolved using petroleum-based solvent streams that have been identified to possess high solvent power. The dissolved material can then be processed and recovered in the refinery using conventional refining operations. A water wash following removal of the organic materials is effective to remove the inorganic materials that can then be disposed of without the complications of the having to treat the oily organics along with them. A beneficial part of the method includes mixing and heating to improve the dissolution of soluble materials in both steps of the process.
