US Patent:

20110184213, Jul 28, 2011
Filed:

Jul 28, 2010
Appl. No.:

13/061122
Inventors:

Yizu Zhu - Lexington MA, US
Johan Van Walsem - Acton MA, US
International Classification:

C07C 29/78
US Classification:

568913
Abstract:

The present invention provides fractional condensation apparatuses, systems and methods that can recover volatile products from highly diluted liquid and vapor feed mixtures with high purity and recovery yield, both in batch and continuous distillation, while being also designed to achieve low-cost and efficient recovery processes. Single apparatuses and columns can be connected to each other to expand or shrink the column length for desired separation. The apparatuses, systems and methods can be applied to separate mixtures with both narrow and wide boiling point ranges.

C07C 67/08
US Classification:

560204, 205440, 562597, 562579, 568864
Abstract:

The present disclosure is a method and system for production of oxalic acid and oxalic acid reduction products. The production of oxalic acid and oxalic acid reduction products may include the electrochemical conversion of COto oxalate and oxalic acid. The method and system for production of oxalic acid and oxalic acid reduction products may further include the acidification of oxalate to oxalic acid, the purification of oxalic acid and the hydrogenation of oxalic acid to produce oxalic acid reduction products.
