The invention relates to a method for the catalytic hydro-processing of a petroleum feedstock of the gas oil type and of a biological feedstock containing vegetal oils and/or animal fats, in a catalytic fixed-bed hydro-processing unit, said method being characterised in that the petroleum feedstock is introduced into the reactor upstream from the biological feedstock. The invention also relates to a catalytic hydro-processing unit for implementing said method, and to a corresponding hydro-refining unit.

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 process for producing alkyl esters useful in biofuels and lubricants by transesterifying glyceride- or esterifying free fatty acid-containing substances in a single critical phase medium is disclosed. The critical phase medium provides increased reaction rates, decreases the loss of catalyst or catalyst activity and improves the overall yield of desired product. The process involves the steps of dissolving an input glyceride- or free fatty acid-containing substance with an alcohol or water into a critical fluid medium; reacting the glyceride- or free fatty acid-containing substance with the alcohol or water input over either a solid or liquid acidic or basic catalyst and sequentially separating the products from each other and from the critical fluid medium, which critical fluid medium can then be recycled back in the process. The process significantly reduces the cost of producing additives or alternatives to automotive fuels and lubricants utilizing inexpensive glyceride- or free fatty acid-containing substances, such as animal fats, vegetable oils, rendered fats, and restaurant grease.

The invention relates to a method of treating feedstocks coming from renewable sources, so as to produce gas-oil fuel bases of excellent quality.

The invention relates to a method for obtaining, from such feedstocks, high yields of gas-oil bases.

The invention discloses a baked staple food for pets, which is prepared from raw materials comprising animal raw materials, grain powder, microbial protein, plant and animal protein, animal fat, vegetable oil, an antioxidant, a water-retaining agent, calcium acid phosphate and/or a dietary supplement, wherein the animal raw materials are fresh animal raw materials, and may be one or more of beef, chicken, mutton, rabbit meat, duck, goose meat, fish, pork, beef liver, beef lung, chicken liver, rabbit liver, rabbit lung, pork liver and pork lung; the animal raw material content of all the raw materials is 10 to 60 mass percent; and the grain powder content of all the raw materials is 10 to 40 mass percent. The staple food for the pets is prepared completely from the fresh raw materials, is healthy, nutrient, highly palatable, digestible, and more favorable for strengthening bones and enhancing the physique of the pets, and can maximally reduce discomfort caused by diet change and effectively improve the intestinal tract function of dogs.

An apparatus and method for producing fatty acid alkyl esters from fatty acids derived from vegetable oils and animal fats with an alkaline solution dissolved in stoichiometric or near stoichiometric levels of a monoalkyl alcohol to form a mixture. The method further comprises emulsifying the mixture as a means to reach a completed chemical reaction state in a reactor section, wherein the oils or fats are transesterified into fatty acid alkyl esters. The transesterification occurs when the natural boundary surfaces of the immiscible mixture are enlarged by ultrasonic cavitation in the reaction section and the transesterification is performed at, or near atmospheric pressure. The method finally includes, after reaching the chemical reaction state, separating residues from the fatty acid alkyl ester in a gravitational phase separation section.

A process for preparing the biological diesel oil from the animal fat or vegetative oil with high acid number includes esterifying by glycerine under existance of strong acid catalyst, distilling in azeotropic solvent for removing water, mixing with methanol, transesterifying reacting to remove glycerine, water washing, and low-temp treating for removing high-smelting-point substances to obtain methyl ester of fatty acid, which is just the biological diesel oil.

In an economical and efficient process and apparatus for producing biofuel from waste oil, such as vegetable oils and animal fats, waste oil is esterified with alcohols to produce alcohol esters and the by-products of the transesterification reaction are recovered. Static pressure may be used as well as continuous flow-through reaction vessels and separation tanks without the need for additional pumps. There may also be specialized reaction tanks that have vertical rotating feed tubes having separators and inlet and outlet openings. The method and device achieves efficient production of biofuel while employing reaction and mixing tanks having a limited size, which in turn permits a smaller plant layout or “footprint”. For example, the largest tank may be in a size of about 36/100,000 times the desired plant output in gallons per year. The benefits of the process and apparatus include minimal space for a plant; minimal on-site feedstock needed therefore minimal on-site storage is needed; minimal capital costs to build a plant e.g., reduction by about fifty to sixty five percent (50 to 65%); reduction in construction time from typically over one year to under three months in many plants; minimal energy usage, e.g., reduction by about sixty percent (60%); minimal labor costs due to the automatic continuous flow; minimal pumps needed thereby reducing pump operation and maintenance costs; environmentally friendlier and safer plant design; and due to smaller plant footprint, lower capital cost and minimal construction time enables site selection much nearer to the raw material supplies, thereby minimizing or even eliminating transportation costs for yellow grease or vegetable oil.

Methods are disclosed for the treatment of feedstocks comprising a fatty acid- or triglyceride-containing component to remove contaminants that are detrimental to the conversion of such feedstocks to hydrocarbons, and especially biofuel fractions such as diesel or aviation biofuels. Contaminants contributing to the presence of trace elements in animal fats and/or plant oils, as components of feedstocks, hinder the ability to catalytically convert these feedstocks, for example by hydroprocessing, to biofuels.

The invention provides efficient, inexpensive, and environmental friendly catalysts and catalyst systems. The catalysts can be used to catalyze esterification and/or transesterification reactions, for example, for the preparation of biodiesel. Kiln dust, such as cement kiln dust (CKD) or lime kiln dust (LKD) can be used to convert a variety of feedstock acids and/or esters to biodiesel in high yield under mild conditions. The CKD and LKD catalyst systems are recyclable esterification or transesterification catalysts that can be used to prepare biodiesel, such as methyl soyate, from various feedstocks, including vegetable oils and animal fats.
