Definitions
- the reaction process comprises the catalytic conversion of sugars to at least one of ethylene glycol and propylene glycol by sequential retro-aldol catalytic conversion (first catalyst) to intermediates and catalytic hydrogenation (second catalyst) of intermediates to at least one of ethylene glycol and propylene glycol (“lower glycol”).
- first catalyst retro-aldol catalytic conversion
- second catalyst catalytic hydrogenation
- the retro-aldol catalyst is homogeneous and the hydrogenation catalyst is heterogeneous.
- This process is complex and is subject to many reactions, catalytic and non-catalytic. For instance, sugars can isomerize, and intermediates can react to by-products, all of which adversely affects selectivity to the sought lower glycol.
- catalytic metals refers to metals that are not necessarily in a catalytically active state, but when not in a catalytically active state, have the potential to become catalytically active.
- Catalytic metals can provide catalytic activity or modify catalytic activity such as promotors, selectivity modifiers, and the like.
- Design space and model predictive control are well known and are multivariate. The former is based upon models and manipulative inputs values are maintained to windows of acceptable operation. Where manipulative inputs are interrelated, the design space control systems can be designed with predictive models such that adjustments in one manipulative input coincide with adjustments in one or more other manipulative inputs. The later considers not only the instantaneous state of the process but also the future state of the process.
- the models can be developed on, for instance, a linear or quadratic models. These models can be derived from empirical data and the performance of the process with respect to process objectives. With respect to model predictive control, data from the process can be used to refine the future predictive aspect of the models.
- the control systems can be open loop or closed loop, and where closed loop, the loop can be the entire plant or a portion thereof. As this disclosure pertains to an unmodulated, sequential catalytic conversion, the control systems address at least the reaction zone.
- a raw material is continuously or intermittently introduced into the reaction zone which contains a medium.
- a raw material which may be one or more reactants to produce the chemical product, can be the predominant component of the medium.
- a substantially inert material can be the predominant component of the medium.
- the medium where a substantially inert material is the predominant component of the medium, can be provided by separately feeding the inert material to the reaction zone or by feeding at least a portion of the inert material in combination with a raw material. Where an inert material is used to form the medium, it can be in the gas phase as it passes through the reaction zone or it can be in the liquid phase.
- the withdrawn medium from the reaction zone is typically the intermittent or continuous stream passing from the reaction zone.
- the medium withdrawn from the reaction zone can be a single stream or may be divided into two or more aliquot streams, any of which can be used to determine concentrations of components.
- the concentration of at least one of the by-product, intermediate, or tracer, as well as the concentration of the chemical product for determining conversion efficiency can be determined from samples of medium from the reaction zone. It should be understood that ascertaining the concentration of a component can be used to determine the amount of that component in a stream of a known volume. Hence, even if the process parameter input is an absolute amount of catalytically active species of a component in the withdrawn stream, it is tantamount to the concentration.
- the raw material comprises carbohydrate which is most often at least one of pentose and hexose or compounds that yield pentose or hexose.
- pentose and hexose include xylose, lyxose, ribose, arabinose, xylulose, ribulose, glucose, mannose, galactose, allose, altrose, idose, talose, and gulose fructose, psicose, sorbose, and tagatose.
- Most bio-sourced carbohydrate feedstocks yield glucose upon being hydrolyzed.
- a homogeneous, tungsten-containing retro-aldol catalyst can deposit a tungsten-containing compound or complex on the hydrogenation catalyst and adversely affect the activity of the hydrogenation catalyst.
- a continuous or intermittent cycling of the amount of tungsten-containing catalyst can result in removal of at least a portion of the deposited tungsten compound or complex.
- the temperatures for hydrogenation reactions are frequently between about 230° C and 300° C, say, between about 240° C and 280° C.
- the pressures are typically in the range of about 15 to 200 bar, say, from about 25 to 150 bar.
- the hydrogenation reactions require the presence of hydrogen as well as hydrogenation catalyst.
- Hydrogen has low solubility in aqueous solutions.
- the concentration of hydrogen in the aqueous, hydrogenation medium is increased with increased partial pressure of hydrogen in the reaction zone.
- the pH of the aqueous, hydrogenation medium is often at least about 3, say, from about 3 or 3.5 to 8, and in some instances from about 3.2 or 4 to 7.5.
- 1,2-butanediol concentration is used as a process parameter input
- the 1,2-butanediol can result from the reaction between two glycolaldehyde molecules or from the dehydration of a tetrose.
- the general rule is that an increase in the 1,2-butanediol concentration is reflecting a loss of hydrogenation catalyst activity in the reaction zone, all other things remaining substantially the same.
