[ATWELL, H. V.] (The Texas Co.). Control
of Catalytic Conversions. United
States Patent 2,438,029, Mar. 16, 1948: appl. Filed May 3, 1944, Serial No.
533,900; 3 claims (Cl.
23-1). Chem. Abs., vol.
42, 1948, p. 4334. Reactions
promoted by finely divided catalyst, specifically the hydrogenation of CO on Co,
are controlled by recycling and heating or cooling the liquids in the reactor.
Catalyst is retained in the reactor by setting out in an enlarged section
at the top of the reactor. For
example, a stream comprising 1 mol. CO:2 mol, H2 preheated to 365°-380°
F. is brought into contact with catalyst suspended in a hydrocarbon fraction b
450°-600°
F. For the production of
hydrocarbons, recycling is adjusted to maintain the reactor between 380°
and 420°
F.: for oxygenated products, a higher temperature is desirable. |
