ABSTRACT:
The invention is an improvement in the prior art processes for producing a microorganism using ethylene as a carbon source. The improvement comprises:
1. hydrating ethylene by contacting ethylene and water, both being in the vapor phase, with a supported phosphoric acid catalyst to form an aqueous-phase effluent comprising ethanol, diethyl ether, acetaldehyde, dissolved phosphate and water;
2. feeding said effluent without substantial purification to a microorganism fermentation zone; and
3. withdrawing from the fermentation zone an effluent and separating said microorganisms from said effluent and recycling to said hydration zone at least a portion of the unreacted water, ethanol, ether and aldehydes along with excess residual salts.
