Return to Russian/Soviet Patent Table of Contents A Method To Produce Ethane/Ethylene
Abstract This invention relates to combined process to produce ethane and/or ethylene from carbon monoxide and hydrogen at elevated temperature and pressure in the presence of the Fischer-Tropsch catalyst, including the production of reaction mixture containing hydrocarbons. The process is carried out at a temperature of 150-450°C, a pressure of 1 to 75 atm and molar ratio of hydrogen to carbon monoxide (1-5):1. To increase the target product yield, the reaction mixture is pyrolized at 799-846°C and at hydrogen to hydrocarbons molar ratio ranging from 1:30 to 1:1. Then the target products are separated. |
