    • The present disclosure relates to a process and a process plant for conversion of a reactive liquid feedstock stream containing at least 40 wt% carbon, comprising the steps of a. directing a diluent stream, having a first combined hydrogen consumption potential and the reactive liquid feedstock stream as a combined stream having a first hydrogen consumption potential, to contact a material catalytically active in hydrotreatment which during operation has a lowest temperature of at least 80°C and a highest temperature of less than 250°C in the presence of dihydrogen, b. withdrawing a stabilized composition stream having a second combined hydrogen consumption potential which is less than 80% and more than 10% of the first hydrogen consumption potential, c. providing an amount of the liquid phase of said stabilized composition stream as said diluent stream wherein the hydrogen consumption potential for a composition shall be understood as the amount of hydrogen required for conversion of the composition into a saturated hydrocarbon. This has the associated benefit of the diluent being only partly converted and thus having a chemical nature favoring miscibility with the reactive feedstock, such that material catalytically active in hydrotreatment is contacted with a mixed liquid which is uniform, and which due to the dilution is less prone to polymerization and has a higher heat capacity, relative to the reactivity.

    • The present disclosure relates to a production plant and a method for production of a synthetic gasoline product from a synthetic hydrocarbon mixture produced by post-treatment of a synthetic gasoline product comprising less than a specified concentration of olefins, such as 6 vol% or 11 vol% from a first synthetic hydrocarbon mixture 5produced from a mixture of reactive oxygenates, said first synthetic hydrocarbon mixture having T90 of less than 140°C and comprising at least said specified concentration of olefins and a second synthetic hydrocarbon mixture, produced from a mixture of re-active oxygenates, said second synthetic hydrocarbon mixture having T90 of more than 150°C said method comprising the steps of10a. directing the second synthetic hydrocarbon mixture to contact a material catalytically active in hydrocracking under effective hydrocracking conditions, to provide a hydrocracked second synthetic hydrocarbon mixture,b. directing said first synthetic hydrocarbon mixture to contact a 15material catalytically active in olefin hydrogenation, to provide a hydrogenated hydrocarbon mixture, wherein said hydrocracked second synthetic hydrocarbon mixture is either added to the first synthetic hydrocarbon mixture upstream contacting said material catalytically active in olefin hydrogenation or it is added to hydro-20genated hydrocarbon mixture, downstream contacting said material catalytically active in olefin hydrogenation to provide said synthetic gasoline product.This has the associated benefit of enabling a flexible production of synthetic gasoline adhering to strict specifications or intermediate specifications for boiling point and con-25centration of olefins as required.
