AI Technical Summary

Technical Problem

Existing hydrocarbon production catalysts using carbon dioxide and hydrogen as raw materials have a high proportion of olefins, leading to low productivity of LPG (Liquefied Petroleum Gas), which consists of propane and butane.

Method used

A hydrocarbon production catalyst containing iron, lanthanum, and sodium, or iron, lanthanum, sodium, and cobalt, with specific molar and mass percentages, and a method involving a precipitation and impregnation process to enhance catalyst activity, including a step with a zeolite decomposition catalyst.

Benefits of technology

The catalyst significantly increases the productivity of LPG by improving the hydrogenation ability and carbon dioxide conversion rate, favoring the production of saturated hydrocarbons with 3 to 4 carbon atoms.
