| Abstract: | The catalysts for the etherification of light FCC gasoline are prepared by supporting different heteropolyacids on activated carbon.The catalytic performance of them to the etherification of light FCC gasoline is studied.It is shown that the supported heteropolyacid catalyst prepared under the conditions of the reaction temperature of 75 ℃,the LHSV of 1.0 h-1,the methanol/olefin molar ratio of 1.0,selecting Na8GeW11O39·xH2O as the active component of catalyst and its supported mass fraction of 20%,and proper etherified process parameters has the best catalytic activity,and the volume fraction of ether in the product can reach to 11.76%,which proves that the catalyst has application prospects. |
