A process for the hydrotreatment of a feed obtained from renewable sources in which the total stream of feed F is divided into a number of different part-streams of feed F1 to Fn equal to the number of catalytic zones n, where n is 1 to 10. The mass flow rate of hydrogen sent to the first catalytic zone represents more than 80% by weight of the total mass flow rate of hydrogen used. The effluent from the reactor outlet undergoes at least one separation step. A portion of the liquid fraction is recycled to the catalytic zones in a manner such that the local recycle ratio for each of the beds is 2 or less, and the local dilution ratio over each of the beds is less than 4.

A process for hydrotreatment of a feed from renewable sources such as vegetable oils for the production of paraffinic hydrocarbons comprising pre-treatment by crystallisation and/or precipitation allowing the elimination of insoluble inorganic impurities under hydrotreatment conditions. The flow of the total feed is divided up into a certain number of different, part flows equal to the number of catalytic zones in the reactor, and the different part flows are injected in the successive catalytic zones in increasing proportions to produce an effluent containing paraffinic hydrocarbons.

Production of paraffin fuels using renewable materials by a continuous hydrotreatment comprising a pre-treatment step

A process for hydrotreatment of a feed from renewable sources such as vegetable oils for the production of paraffinic hydrocarbons comprising a pre-treatment step by crystallization and/or precipitation and pre-hydrogenation of the feed under hydrogen allowing the elimination of insoluble inorganic impurities under hydrotreatment conditions and improved exothermal management of the reaction. The effluent is separated to a gas fraction and a liquid fraction containing paraffinic hydrocarbons, a portion of said liquid fraction is recycled.

A process for the production of surfactant compounds from a feed obtained from renewable sources, comprising hydrotreatment of feed in a fixed bed reactor having a plurality of catalytic zones disposed in series containing a hydrotreatment catalyst. The feed is injected in a staggered manner and injected in increasing proportions in order to produce an effluent containing at least hydrocarbon compounds containing linear paraffins.

Process for the production of surfactants from renewable materials, comprising a step for hydrotreatment and a step for transforming paraffins into surfactants

A process for hydrotreating a feed originating from renewable sources such as vegetable oils to produce paraffinic hydrocarbons in the presence of hydrogen in excess over the theoretical hydrogen consumption and under hydrotreatment conditions in a fixed bed reactor having a plurality of catalytic zones disposed in series and comprising a hydrotreatment catalyst. The total feed flow is divided into a certain number of different part flows equal to the number of catalytic zones in the reactor; the various part flows are injected into the successive catalytic zones in increasing proportions to produce an effluent comprising paraffinic hydrocarbons. The effluent undergoes a separation step in order to separate a gas fraction and a liquid fraction containing the paraffinic hydrocarbons. At least a portion of said this liquid fraction is recycled to the first catalytic zone so that the weight ratio between said recycle and the part flow introduced into the first catalytic zone is 10 or more.

Process for the continuous hydrogenation of triglyceride containing raw materials in a fixed bed reactor system having several catalyst beds arranged in series and comprising at least one hydrogenation catalyst comprising an active phase constituted by a nickel and molybdenum element. The raw material feed, hydrogen containing gas and diluting agent are passed together through the catalyst beds at hydrogenation conditions. The raw material feed stream as well as the stream of hydrogen containing gas are divided into an equal number of different partial streams. These are each passed to one catalyst bed in such a manner that the weight ratio of diluting agent to raw material feed is essentially the same at the entrance of all catalyst beds and does not exceed 4:1. The claimed process is preferably conducted at low temperatures and allows the utilization of existing units due to the low recycle ratio.
