WebOur study showed that the activity of bimetallic Pt-Re catalysts toward the APR of xylose strongly depends on the level of Re dopant. In particular, the Pt 3-Re 1 /SiO 2 catalyst exhibited the higher H 2 selectivity compared to the catalysts having the higher amount of Re dopant (Pt 3-Re 2 /SiO 2 and Pt 3-Re 3 /SiO 2). WebThermal reforming alters the properties of low-grade naphthas by converting the molecules into those of higher octane number by exposing the materials to high temperatures and pressures. Catalytic reforming uses a catalyst, usually platinum, to produce a similar result.

This is done in a naphtha hydrotreater that may be considered part of the reformer, or a separate process unit. Next, the feed is sent through a series of 3-4 reactor vessels.

WebHoudriforming was introduced by the Houdry Process Corporation, Philadelphia, in 1950 and is a fixed-bed reforming process employing a platinum-alumina catalyst. It operates with a catalyst temperature of 875 to 950°F and an operating pressure of 250 to 600 psig. WebA nickel catalyst is used. This is the steam reforming operation. However, we will add another important reaction to recover a little more dihydrogen using the carbon monoxide obtained previously: the “Water-gas shift reaction” (= “catalytic conversion” or “vapor conversion of water“): CO + H2O = CO2+H2.
