LF307 combined methanol synthesis catalyst is a kind of Cu based three elements catalyst. It replaces typical Zn-Cr based catalyst, making methanol process conditions more mild, i.e., medium and low pressure replacing high pressure synthesis, low temperature operation replacing high temperature operation. With LF307, CO shift ratio is effectively improved. It is mainly used for methanol synthesis with CO and H2 in the combined production of ammonia and methanol, also used in medium and high pressure methanol synthesis.
