  • the present invention generally relates to a process which utilizes carbon more efficiently in the synthetic production of chemicals and fuels including gasoline.
  • syngas a synthesis gas
  • coal a synthesis gas
  • Syngas from natural gas is primarily used to produce methanol, the chemical starting point of the plastics industry.
  • Other products from syngas include alkanes, olefins, oxygenates, and alcohols such as ethanol.
  • syngas Any carbonaceous material, in particular, biomass such as agricultural wastes, forest products, grasses, and other vasosic material, including municipal waste streams, may be converted to syngas.
  • biomass such as agricultural wastes, forest products, grasses, and other vaiulosic material, including municipal waste streams.
  • the most common methods are gasification, pyrolysis and hydro-treating, which produce a syngas which is a mixture of not only carbon monoxide and hydrogen, but includes carbon dioxide and carbon particles, and whatever other elements are present in the feedstock, in gaseous form and must be removed before the syngas is processed.
  • the newly-formed syngas is cleaned and conditioned before sending to the first reactor in the process.
  • anything other than carbon monoxide and hydrogen are removed to the level possible and practical, but is especially cleaned of those elements which would foul compressors or poison catalysts downstream.
  • Carbon dioxide is generally removed as well, simply to reduce the volume of process gases and to ensure that it does not act as a reagent in the subsequent chemical reactors. The carbon dioxide is typically then vented.
  • gas reformer included in the process train. Its purpose is to convert any unreacted gases or products, from a step, or steps in the process train, into syngas. The syngas thus formed are then fed back into the appropriate reactor. Any carbon dioxide formed as a result is typically removed from the newly-formed syngas prior to sending on.
  • a common method to utilize recycled gases is Autothermal Reforming (ATR). This method produces syngas using methane as example, is as follows:
  • ATR The advantage of ATR is that the H2:CO can be varied, this is particularly useful for producing dimethyl ether, which requires a 1:1 H2:CO ratio.
  • Dry Reforming DR
  • DR Dry Reforming
  • the instant invention teaches a novel method to utilize carbon dioxide in the production of any synthesis of chemicals or fuels in which the syngas ratio of carbon monoxide to hydrogen is not ideal for the purpose, and when carbon dioxide and other hydrocarbon gases are present.
  • CDRS carbon dioxide removal system
  • a novel aspect of the instant invention is that the volume of carbon dioxide removed from the syngas is controlled, leaving a measured amount therein.
  • the syngas is then fed directly into a Dry Reformer, which is novel placement of this reactor.
  • gas reforming is used to convert any unused gases resulting from catalytic steps in a process, but it is not a part of the main stream.
  • the problem to be solved is to eliminate the production and venting of carbon dioxide to the maximum extent possible.
  • the solution suggested in the instant invention is the novel placement of a gas reformer, using heat, pressure, a catalyst and a measured amount of carbon dioxide.
  • the new syngas stream thus produced adds to the yield of product and reduction in carbon dioxide vented.
  • the instant invention will help improve the economic competitiveness of biofuel or biochemical production, and has the added advantage of benefiting the environment by the reduction of carbon emissions.
  • Another advantage of this invention is that it utilizes equipment already in the marketplace, proven commercially, and therefore is not inhibiting to commercialization.
  • FIG. 1 is a block-flow diagram depicting a general process for conversion of renewable materials into end products.
  • FIG. 1 at 10 shows the main (preferred) embodiment of the instant invention.
  • Biomass 1 is gasified 2 in a fluidized bed using steam as fluidtzer and oxygen in substoichiometric volumes to produce Synthesis Gas A 3.
  • the hot syngas emerging from the gasifier is typically composed of carbon monoxide, hydrogen, methane, propane, ethane, carbon dioxide, and possibly heavier hydrocarbons greater than C4, and also may contain contaminants, such as carbon particles, sulphur, chlorine, and trace metals and minerals, according to the composition of the feedstock used and the conditions in the gasifier.
  • Syngas B 5 The syngas is cleaned and conditioned 4 in a series of steps to remove all contaminants, using industry-standard processes and equipment selected on the basis of the composition of the initial feedstock, leaving only gaseous components, to form Syngas B 5.
  • a sample of Syngas B is withdrawn and sent to the Gas Analyzer 13 to quantify the composition of the gases in general and the carbon dioxide content in particular. Feedback from this analysis is sent to the controls which regulate the removal of carbon dioxide at the Carbon Dioxide separator 7, to form Syngas C 9 consisting of carbon monoxide, hydrogen, hydrocarbons and a determined amount of carbon dioxide.

  • Syngas F 12 enters the dimethyl ether reactor 14 after being appropriately compressed according to the reactor conditions.
  • the reactor is coupled with a separator (not shown separately) which removes any carbon dioxide from the exit products, and which is then vented 15.
  • Dimethyl ether is fed to the gasoline reactor 16 where the dimethyl ether is converted into gasoline range hydrocarbons with skeleton of C5 to C12.
  • Products exiting the reactor are sent to a separator which removes the water 18 formed by the reaction, and sends the light hydrocarbon gases 19, consisting of methane, ethane, propane and butane formed during the reaction back to the Syngas Reformer 10.
  • the gasoline product 20 is sent to storage.
  • the advantages of this control result in the more efficient use of the carbon in the feedstock and is in contrast to current industry practices. It is common to remove carbon dioxide at different points in the reaction stream, depending on the end product and reactors involved. Recently the carbon dioxide is used in dry reforming of unconverted or recycled gases, but that is typically done outside the main reaction process steps, with the resulting synthesis gas fed into the reactor(s).
  • the instant invention is more efficient, and because of the control mechanism, can ensure that the carbon it utilized in a controlled manner without having to vent more than absolutely necessary.
  • the instant invention is appropriate for the production of Fischer-Tropsch liquids, which conventionally produces excess carbon dioxide.
  • the instant invention has valuable industrial applicability to any process which converts renewable material into synthesis gas for further processing to make chemicals or fuels.
  • the placement of the gas reformer immediately after the syngas cleaning allows for immediate and regulated composition of the syngas for the subsequent reaction(s) in the process in this way, the carbon content of the feedstock is utilized to the maximum, instead of being vented as carbon dioxide.

Abstract

L'invention concerne un procédé d'optimisation du rendement de produits chimiques ou combustibles synthétiques à partir d'une charge d'alimentation organique. Le procédé comprend la production d'un gaz de synthèse, suivi d'un nettoyage gazeux pour éliminer les impuretés. Il intègre ensuite un système de retrait de dioxyde de carbone réglable qui est immédiatement suivi d'une étape de reformage à sec qui accepte le gaz de synthèse nettoyé contenant une quantité mesurée de dioxyde de carbone. La quantité de dioxyde de carbone nécessaire dans le reformeur à sec est déterminée par la quantité et le type d'hydrocarbures contenus dans le gaz de synthèse et dans des gaz recyclés provenant de réactions de traitement en aval. Seul le dioxyde de carbone en excès au-delà des exigences du reformage est ventilé. Ce procédé augmente le rendement du produit et réduit les émissions de carbone totales.
