Abstract:
A linear alkyl benzene product and production of linear alkylbenzene from a natural oil are provided. A method comprises the step of deoxygenating the natural oils to form a stream comprising paraffins. The paraffins are dehydrogenated to provide mono-olefins. Then, benzene is alkylated with the mono-olefins under alkylation conditions to provide an alkylation effluent comprising alkylbenzenes and benzene. Thereafter, the alkylbenzenes are isolated to provide the alkylbenzene product.
Abstract:
Methods and systems are provided for producing a fuel from a renewable feedstock. The method includes deoxygenating the renewable feedstock in a deoxygenation zone to produce hydrocarbons with normal paraffins. The hydrocarbons with normal paraffins are isomerized to produce hydrocarbons with branched paraffins. The hydrocarbons with branched paraffins are fractionated to produce a naphtha at a naphtha outlet, where the naphtha is further isomerized.
Abstract:
An apparatus and a process for providing a green diesel with improved flow properties. A renewable feed comprising an oil is deoxygenated to provide an effluent. The effluent may be isomerized to improve the qualities of the effluent for use as a diesel fuel. Additionally, the effluent may be filtered to increase the fuel flow properties. As filtration zone can be used, which includes a filter and which may be flushed with a portion of the feed stream to the filtration zone or a portion of filtration zone effluent. The wash stream may be heated.

Abstract:
Processes for the production of linear alkylbenzenes from a renewable feedstock. Prior to converting the side chains of the glycerides and free fatty acids of the feedstock into hydrocarbons, the feedstock is separated into a stream rich in C10 and C14 free fatty acids glycerides having C10 and C14 fatty acid side chains and at least one, preferably two, other glyceride streams. The stream rich in glycerides having C10 and C14 fatty acid side chains can be converted via deoxygenation into a stream rich in C9 to C14 hydrocarbons while the other glyceride streams can be used as vegetable oil. A C10 to C13 hydrocarbon fraction from the stream rich in C9 to C14 hydrocarbons may be dehydrogenated to form olefins which may be reacted with benzene to form linear alkylbenzenes. The linear alkylbenzenes may be used to produce surfactants.

Abstract:
Embodiments of methods for co-production of linear alkylbenzene and oleochemicals from a natural oil are provided. An exemplary method includes fat splitting the natural oil to form a stream comprising free fatty chains. The method includes fractionating the stream of free fatty chains to separate a first portion of free fatty chains and a second portion of free fatty chains. Further, the method includes processing the first portion of free fatty chains to provide the alkylbenzene product and processing the second portion of free fatty chains to form the oleochemical products.
Abstract:
Methods and systems for hydrogen self-sufficient production of hydrocarbons from a renewable feedstock are provided. An exemplary method includes providing a renewable feedstock; contacting the renewable feedstock and hydrogen from a hydrogen stream with one or more catalysts to generate an effluent comprising n-paraffins and by-product hydrocarbons having 9 or fewer carbon atoms; separating the by-product hydrocarbons from the effluent to generate a hydrocarbon by-product stream; and feeding the hydrocarbon by-product stream to a hydrogen plant to generate the hydrogen stream. In this exemplary embodiment, the by-product hydrocarbons constitute the entire feed and fuel of the hydrogen plant, and wherein no hydrogen is added from an external source.
