摘要： The present invention relates to a process for producing propylene and ethylene from a light hydrocarbon stream comprising essentially ethane and butane. The process involves a non-catalytic cracking of ethane and normal-butane followed by a metathesis of ethylene and 2-butene to increase the propylene yield. Optionally the by-produced iso-butane is dehydrogenated and subsequently the produced iso-butene is converted to other valuable products like di-isobutylene, alkylate for gasoline blending, tertiary-butyl-ethers, polyisobutylene, methyl-metacrylate or isoprene.

摘要： The present invention relates to a process for the conversion of ethanol to make essentially ethylene and propylene, comprising:
a) introducing in a reactor (A) a stream comprising ethanol under a partial pressure at least about 0.2 MPa,
b) contacting said stream with a catalyst (A1) in said reactor (A) at conditions effective to convert at least a portion of the ethanol to ethylene, propylene and olefins having 4 carbon atoms or more (C4+ olefins),
c) recovering from said reactor an effluent comprising:
ethylene, C4+ fraction,
propylene and various hydrocarbons,
water,

d) fractionating said effluent of step c) to remove water and unconverted ethanol, to get a stream (D) comprising ethylene and C4+ olefins,
e) introducing at least a part of said stream (D) optionally mixed with a stream (D1) comprising C4+ olefins in an OCP reactor under the condition that said mixture (D)+(D1) comprises at least 10wt% of C4+ olefins,
f) contacting said stream comprising at least a part of (D) and the optional (D1) in said OCP reactor with a catalyst which is selective towards light olefins in the effluent, to produce an effluent with an olefin content of lower molecular weight than that of the feedstock,
g) fractioning said effluent of step f) to produce at least an ethylene stream, a propylene stream and a fraction consisting essentially of hydrocarbons having 4 carbon atoms or more.
