摘要：

Novel Cu-Cr based catalysts with alumina promotion have been prepared and studied in low-temperature methanol synthesis (LTMS) in a slurry reactor. The new method of co-precipitation from the sol state gave better results than those of three other preparation methods. From the results of temperature programmed desorption and XRD, there were more active sites in the presence of alumina.
