System 150 bar optional (H2 - N2 - CO2 - CO - ……. And so on) mass flow controls can be delivered at the desired flow rate. Optional catalyst gases are heated prior to column entry. Optionally, liquid can be sent to the system with the catalyst pre-column liquid feed pump at the desired flow rate under high pressure. The column furnace is suitable for 1,000 ° C operation. There is thermowell in the column and thermocouple temperature measurement is done. There are special filter elements at the entrance and exit of the columns. The lines are heated at the outlet of the column to ensure that the product does not freeze. The product is collected in a pressure chamber. The outlet gas is kept at the desired pressure by BPR. At the outlet there is a mass flow meter.
