Process for the continuous production of ethylene glycol from carbohydrates
TL;DR: In this article, a continuous process for converting carbohydrates to ethylene and propylene glycol is described, where the carbohydrates are mixed with water and passed through a reactor at a temperature that hydrolyzes the carbohydrate mixture at least partially to monosaccharides.
Patent
Continuous processes for the highly selective conversion of aldohexose-yielding carbohydrate to ethylene glycol
TL;DR: Continuous processes for making ethylene glycol form aldohexose-yielding carbohydrates are disclosed in this paper, which enhance the selectivity to ethylene gaseous glycol.

Chrisman Ray,Bunning Donald,Albin Brooke,Nunley Mark,Bradford Michael,Schreck David James,Kapicak Lou +6 more
TL;DR: In this paper, the conversion of carbohydrate to ethylene glycol by retroaldol catalysis and sequential hydrogenation using control methods having at least one of acetol (hydroxyacetone) and a tracer as inputs is described.

Method for continuous production of ethylene glycol from carbohydrates
シュレック,デヴィッド,David Schreck,クリスマン,レイ,Chrisman Ray,アルビン,ブルック,Albin Brooke,クリントウッド,ナイ,Clinton Nye +7 more
TL;DR: In this paper, a continuous method for converting carbohydrates to ethylene and propylene glycol was proposed, where the carbohydrates are mixed with water and passed through a reactor at a temperature of hydrolyzing the carbohydrate mixture at least partially to monosaccharides, the reactor having a first zone A comprising a retro-aldol catalyst and a second zone B comprising a reducing catalyst.
Patent
Methods for operating continuous, unmodulated, multiple catalytic step processes
Chrisman Ray,Bunning Donald,Nunley Mark,Albin Brooke,Bradford Michael,Schreck David James,Kapicak Lou +6 more
TL;DR: In this paper, the authors present control methods for continuous, unmodulated, multiple catalytic conversion step processes using at least two catalysts, a first catalyst and a second catalyst, that accommodate changes in the performance of each catalyst and the relative performances of the catalysts.
