A reactor system for carrying out an endothermic catalytic chemical reaction in a given temperature range upon bringing a reactant into contact with a catalyst material. The reactor system includes a reactor unit arranged to accommodate catalyst material including one or more ferromagnetic macroscopic supports susceptible for induction heating where the one or more ferromagnetic macroscopic supports are ferromagnetic at temperatures up to an upper limit of the given temperature range. The one or more ferromagnetic macroscopic supports are coated with an oxide, and the oxide is impregnated with catalytically active particles. The reactor system moreover includes an induction coil arranged to be powered by a power source supplying alternating current and being positioned so as to generate an alternating magnetic field within the reactor unit upon energization by the power source, whereby the catalyst material is heated to a temperature within the temperature range by the alternating magnetic field.

Improvements to the gasifier furnace design and process method to facilitate continuous production of mainly H.sub.2, CO and granulated solid from molten liquid or the liquid slag in the presence of carbonaceous material. It is a method of quenching molten liquid and cooling post quenched hot granulated solid which is done within a long horizontal reaction chamber space of the furnace in the presence of C and H.sub.2O. A moving layer of continuously gas cooled granulated solid protects the moving floor underneath by substantially reducing the possibility of heat transfer from the horizontal reaction chamber to such moving floor and its parts and preventing direct contact between the post quenched hot solid granulates and such moving floor. Such moving floor having plurality of gas passages and is disposed above a plenum that receives gas from outside source and uniformly distributes the gas to pass through all the gas passages.

A plant, such as a hydrocarbon plant, is provided, which has a syngas stage for syngas generation and a synthesis stage where the syngas is synthesized to produce syngas derived product, such as hydrocarbon product. The plant makes effective use of various streams; in particular CO.sub.2 and H.sub.2. The plant does not comprise an external feed of hydrocarbons. A method for producing a product stream, such as a hydrocarbon product stream is also provided.

The present invention concerns a multifunctional catalyst for the conversion of CO.sub.2 into useful products, such as CO via the reverse water gas shift reaction. The catalyst according to the invention efficiently combined a water sorption functionality with at least one catalytic functionality into a single particle, by having a solid water sorbent impregnated with at least one metal capable of converting CO.sub.2 from a gaseous mixture comprising H.sub.2 and CO.sub.2. The catalyst according to the invention allows for higher selectivity in the conversion of CO.sub.2, at more lenient conditions in terms of temperature and pressure, and improved stability of the catalyst itself. The invention also concerns a process for converting CO.sub.2, utilizing the catalyst and the use of the catalyst in the conversion of CO.sub.2.

The present invention describes a processes, systems, and catalysts for the conversion of carbon dioxide and water and electricity into low carbon or zero carbon high quality fuels and chemicals. In one aspect, the present invention provides an integrated process for the conversion of a feed stream comprising carbon dioxide to a product stream comprising hydrocarbons between 5 and 24 carbon atoms in length.

The invention relates to a cyclic method for capturing and utilizing CO.sub.2 contained in a gas stream. The method uses three different materials, a first solid material, a second solid material and a CO.sub.2 sorbent material.

In a first step a first gas stream comprising CO.sub.2 and at least one reductant is brought in contact with the three materials, resulting in an outlet stream comprising water. In a second step, the captured CO.sub.2 from the first step is released and converted to CO to produce a CO rich outlet stream. The invention further relates to an installation for capturing and utilizing CO.sub.2.

An object of the present invention is to provide platinum-tungsten solid solution particles that can be suitably used for catalyst applications and others. Another object is to provide a catalyst with higher catalytic activity than when platinum is used alone. Disclosed are platinum-tungsten solid solution particles comprising platinum and tungsten in solid solution at an atomic level. Also disclosed is a catalyst comprising the platinum-tungsten solid solution particles.

Systems and methods are provided for hydrogenation of CO.sub.2 in a reverse flow reactor environment via a reverse water gas shift reaction. A reverse flow reactor environment is suitable for performing endothermic reactions at high temperatures, where a reactant flow is passed into the reactor in a first portion of the cycle in a first flow direction while a combustion or heating flow is passed into the reactor during a second portion of the reaction cycle from the opposite direction. This can allow for efficient heating of surfaces within the reactor to provide heat for the endothermic reverse water gas shift reaction while reducing or minimizing incorporation of combustion products into the desired reaction products.

A process for the manufacture of a useful product from carbonaceous feedstock of fluctuating compositional characteristics, the process comprising the steps of: continuously providing the carbonaceous feedstock of fluctuating compositional characteristics to a gasification zone; gasifying the carbonaceous feedstock in the gasification zone to obtain raw synthesis gas; sequentially removing ammoniacal, sulphurous and carbon dioxide impurities from the raw synthesis gas to form desulphurised gas and recovering carbon dioxide in substantially pure form; converting at least a portion of the desulphurised synthesis gas to a useful product. Despite having selected a more energy intensive sub-process i.e. physical absorption for removal of acid gas impurities, the overall power requirement of the facility is lower on account of lower steam requirements and thereby leading to a decrease in the carbon intensity score for the facility.

A plant complex may include a unit that produces CO.sub.2-containing gases, a gas conducting system for CO.sub.2-containing gases, a gas/liquid separation system, a reformer that is connected to the gas conducting system and where the CO.sub.2-containing gas reacts with H.sub.2 and/or hydrocarbons to give a CO— and H.sub.2-containing synthesis gas mixture. The reformer is connected to a reactor for producing higher alcohols in which the synthesis gas mixture reacts with H.sub.2 to give a gas/liquid mixture containing higher alcohols. For separating off the alcohols of the gas/liquid mixture, the gas/liquid separation system is connected to the reactor for producing higher alcohols.
