US11148986B1
A method for extracting polyol from a fermentation process is disclosed. The preparing method includes rectifying and purifying PDO (1,3-propanediol) from a polyol fermentation broth after concentration to form a steam condensate, wherein the concentration is a evaporative dehydration; and filtering the steam condensate through a reverse osmosis membrane to form a concentrated solution, wherein the retentate of the reverse osmosis flows back to the evaporative dehydration, and the penetrant of the reverse osmosis can be reused as a fermentation ingredient, as cleaning water or for sewage treatment; and the water content of the concentrated solution after the evaporative dehydration is 5-25 wt %; and the yield of PDO is 99.5%. The preparing method meets the requirements of water resources recycling, reduces the production loss of PDO and BDO (2,3-butanediol) during the concentration, and greatly cuts down on the amount of wastewater.
US11148985B2
A process for producing ethylene and syngas comprising reacting, via OCM, first reactant mixture (CH4&O2) in first reaction zone comprising OCM catalyst to produce first product mixture comprising ethylene, ethane, hydrogen, CO2, CO, and unreacted methane; introducing second reactant mixture comprising first product mixture to second reaction zone excluding catalyst to produce second product mixture comprising ethylene, ethane, hydrogen, CO, CO2, and unreacted methane, wherein a common reactor comprises both the first and second reaction zones, wherein ethane of second reactant mixture undergoes cracking to ethylene, wherein CO2 of second reactant mixture undergoes hydrogenation to CO, and wherein an amount of ethylene in the second product mixture is greater than in the first product mixture; recovering methane stream, ethane stream, CO2 stream, ethylene stream, and syngas stream (CO&H2) from the second product mixture; and recycling the ethane stream and the carbon dioxide stream to second reaction zone.
