Abstract: A process plant and a process for production of a hydrocarbon suitable for use as jet fuel from a feedstock being a renewable feedstock or an oxygenate feedstock, including combining the feedstock with an amount of a liquid diluent, directing it to contact a material catalytically active in hydrodeoxygenation under hydrotreating conditions to provide a hydrodeoxygenated intermediate product, separating the hydrodeoxygenated intermediate product in at least two fractions; a vapor fraction and a liquid fraction, directing at least an amount of the liquid fraction to contact a material catalytically active in isomerization under isomerization conditions to provide an isomerized intermediate product, directing at least an amount of the isomerized intermediate product and a stream comprising sulfur to provide a hydrocracked intermediate product, and fractionating the hydrocracked intermediate product to provide at least a hydrocarbon suitable for use as jet fuel.

Abstract: A process for the removal of nitrous oxide (N2O) contained in a process off-gas in an axial flow reactor. The process includes the steps of (a) adding an amount of reducing agent into the process off-gas; (b) in a first stage passing in axial flow direction the process off-gas admixed with the reducing agent through a first monolithic shaped catalyst active in decomposing nitrous oxide by reaction with the reducing agent to provide a gas with a reduced amount of nitrous oxide and residual amounts of reducing agent; and (c) in a second stage passing the gas with a reduced amount of nitrous oxide and residual amounts of the reducing agent in axial flow direction through a second monolithic shaped catalyst active in oxidation of the residual amounts of the reducing agent.

Abstract: According to the present invention a process is provided for producing glycolide which comprises contacting glycolaldehyde dimer with an oxidizing agent to produce a glycolide product. Preferably, the process is carried out in an aprotic environment, such as in a reaction mixture comprising the glycolaldehyde dimer, the oxidizing agent, the glycolide product and an aprotic solvent.

Abstract: A catalytic reactor comprises a load distributor assembly to evenly transfer a load from equipment (internals) to a reactor support ring or support structure fixed within the reactor shell, thereby maximizing the possible load to be applied to the support ring or support structure without any hot-work modifications and without exceeding the allowable tensions/stress.

Abstract: In a method for the precipitation of particles of a metal carbonate material comprising nickel and manganese in an atomic ratio of 0≤Ni:Mn≤1:3, aqueous solutions comprising sulfates or nitrates of nickel and manganese are mixed with aqueous solutions of carbonates or mixtures of carbonates and hydroxides of sodium or potassium in a stirred reactor at pH>7.5 without the use of a chelating agent. Thereby agglomerated particles are formed without any subsequent process steps, in particular no subsequent process at temperatures higher than the precipitation temperature.

Abstract: A reactor layout for a process of methanol production from low quality synthesis gas, in which relatively smaller adiabatic reactors can be operated more efficiently, some of the inherent disadvantages of adiabatic reactors for methanol production are avoided. This is done by controlling the outlet temperature in the pre-converter by rapid adjustment of the recycle gas, i.e. by manipulating the gas hourly space velocity in the pre-converter.

Abstract: In a novel method for start-up heating of a converting re-actor in an ammonia synthesis plant, the conventional use of a gas fired heater is replaced by inductive heating. The inductive heating is obtained using an alternating high frequency current, which is passed through an inductive coil located inside the reactor, especially mounted inside a pressure shell. The method makes it possible to run reactions at high temperatures and high pressures in a very efficient way.

Abstract: A method for producing methanol comprises the steps of passing a feed stream of methanol synthesis pas through a main methanol reactor containing a methanol synthesis catalyst, to form a mixed gas containing methanol, cooling the mixed gas containing methanol, separating methanol from the mixed pas and heating the mixed gas. The stream of heated mixed gas is passed through an additional methanol reactor containing a methanol synthesis catalyst, and the effluent from the additional methanol reactor is mixed with the feed stream of methanol synthesis gas and passed through the main methanol reactor.
