| Summary: | 碩士 === 國立中央大學 === 化學工程研究所 === 82 === This study includes two parts. In the first part, We try to
synthesis uniform large crystal of AlPO4-5 for materials
application, and study each parameter on the influence of
growing To obtain large and uniform AlPO4-5 by hydrothermal
treatment, when gel comopsition:(C2H5)N:Al2O3:P2O5:
H2)=1.55:1:1:600, aluminua source obtained from hydrosis of
pseudo boehmite is better than In the elimination alcohol of
acetaldehydedimethyl acetal (DMA),the results reveal that,
selectivity over each zeolite catalysts is very high (near
100%),but the aluminaphosplate Under 1 atm , WHSV=27hr-1,With
increasing tempature to 250℃,the conversion of AlPO4-5,SAPO-5
is 100%.Strong acid active site helps the double bond products
