The DTP® (Dominant Technology for Propylene Production) Process is a high-yield propylene production technology in which propylene is produced by using dimethyl ether (DME) or methanol produced from natural gas or other sources as a process feed. In addition, unavailable olefins by-produced from a naphtha cracker also can be used as process feed. The world demand for propylene is expected to increase steadily in the future, but the present supplies of propylene are seen as inadequate to meet this increased demand. In addition, the diversification of feedstock is needed as crude oil prices have soared. With this background, the attention of the propylene industry has become focused on the diversification of feedstock and propylene production processes intended for “on purpose” propylene production. JGC and Mitsubishi Chemical have developed a DTP catalyst which ensures high propylene selectivity and stable performance and is now aiming at the early development of a commercial process which can meet the increasing demand for propylene. We are jointly planning the demonstration test.
Features
A DTP catalyst (zeolite type) ensures high propylene selectivity and stable performance.
A fixed-bed adiabatic reactor is adopted as a DTP reactor. The reactor is easy to operate.
A high propylene yield is attained by hydrocarbon recycling.
Applications
Propylene production via methanol from natural gas in gas-producing countries
Propylene production with the use of both fuel grade DME or methanol and unavailable olefins by-produced from a naphtha cracker
Development Results
Establishment of a catalyst manufacturing method for this process
Early confirmation of the feasibility of commercialization through use of a demonstration plant constructed in Mitsubishi Chemical's Mizushima Plant (Construction of this demo-plant will be completed in July 2010.)
