The present invention relates to methods of producing industrial products from plant lipids, particularly from vegetative parts of plants. In particular, the present invention provides oil products such as biodiesel and synthetic diesel and processes for producing these, as well as plants having an increased level of one or more non-polar lipids such as triacylglycerols and an increased total non-polar lipid content. In one particular embodiment, the present invention relates to combinations of modifications in two or more of lipid handling enzymes, oil body proteins, decreased lipid catabolic enzymes and/or transcription factors regulating lipid biosynthesis to increase the level of one or more non-polar lipids and/or the total non-polar lipid content and/or mono-unsaturated fatty acid content in plants or any part thereof. In an embodiment, the present invention relates to a process for extracting lipids. In another embodiment, the lipid is converted to one or more hydrocarbon products in harvested plant vegetative parts to produce alkyl esters of the fatty acids which are suitable for use as a renewable biodiesel fuel.

Provided is a gasoline product containing a combustion improver, and a method for preparing the gasoline product. The combustion improver is added to gasoline to reduce an octane number and thus an ignition point of the gasoline, so that the gasoline product can be used in a compression ignition internal combustion engine. The combustion improver-containing gasoline product is a low-octane number gasoline, and is capable of being ignited through compression by an internal combustion engine having a compression ratio in the range from 12 to 22.

A biomass-based long-chain alcohol ether oxygenated additive and a preparation method and application thereof are disclosed. The additive used agricultural and forestry wastes as raw materials, and has a general chemical formula of R—(O—C.sub.1-3).sub.n—R—OH. The preparation method includes the following steps: step 1, performing drying pretreatment on biomass raw materials, performing rapid pyrolysis under an inert atmosphere to obtain a pyrolysis product containing water, gases, water-phase bio-oil and oil-phase bio-oil, separating out the water-phase bio-oil and performing catalytic hydrogenation on the water-phase bio-oil to obtain polyols; step 2, performing catalytic dehydration on the polyols obtained in step 1 under a basic catalyst system to obtain epoxyalkane; and step 3, making the epoxyalkane obtained in step 2 and methanol undergo a reaction under a molecular sieve catalyst and removing the solid catalyst by separation to obtain the long-chain alcohol ether oxygenated additive.

An integrated refinery process for removing mercaptans from a hydrocarbon stream containing mercaptans and converting by-product disulfide oil to useful products. The process includes introducing the hydrocarbon stream containing mercaptans into an extraction vessel containing an alkaline solution and passing the hydrocarbon stream through an extraction section of the extraction vessel which includes one or more liquid-liquid contacting decks for reaction to convert the mercaptans to alkali metal alkanethiolates. Further, the process includes withdrawing a hydrocarbon product stream free of mercaptans from the extraction vessel and recovering spent caustic containing alkali metal alkanethiolates from the extraction vessel. Additionally, the process includes subjecting the spent caustic containing alkali metal alkanethiolates to air oxidation to produce a by-product stream containing disulfide oils (DSO) and sulfides and processing the by-product stream in a steam cracking unit to produce a DSO free product stream.
