Direct synthesis of LPG from syngas in a single-tube reactor
摘要
Abstract
A hybrid catalyst for the direct synthes is of liquefied petroleum gas (LPG) from syngas was prepared th rough mechanical mixin g of methanols ynthesis catalyst with dehydration catalyst; its catalyt ic performance was tested in a single-tub e reactor with a simulated biogas at 220 ~330 ℃, 1.2 ~5.1 MPa an d a space velocity of 500~3 000 h-1 .The results indicated that the hybrid catalyst hasa good activity; at 325℃, 2.1 MP a, and a space v e locity of 1 500 h-1 , CO conversion and LPG conten t in the hydrocarbons product ar e 72.36% and 71.21%, respectively .At 325℃ and 2.1 MPa, a stable operation can be realiz ed at a spac e velocity below 2 500 h-1 , wh ereas the temper ature cannotb e well controlled at a space velocity ov er 3 000 h-1 ,w hichm ay lead to the catalyst deactivation.The NH3-TPD, XRD, N2 sorption and TPO characterization results suggest that the deposition of coke and decrease of the mount of strong acid sites and surface area are responsible for the catalyst deactivation.关键词
