摘要: A method of making a higher olefin product from a C4+ fraction separated from the hydrocarbon product produced by an oxygenate to olefin reaction unit. The C4+ fraction primarily contains butenes which may be directed to a higher olefin reaction unit without removing isobutenes, butanes, and/or butadiene. The C4+ fraction is particularly well suited for the production of higher olefins because of its high olefin content, low branching number, and low contaminent levels. The invention is also directed to an olefin product composition that is produced by contacting the C4+ fraction with an oligomerization catalyst. The olefin composition is characterized by a relatively high octene content, and octene with a branching number less than 1.4.

摘要: Water reacts on molecular sieve catalysts used in oligomerization reactions and forms oxygenated compounds, in particular organic acids that may cause corrosion problems downstream of the reactor, in particular in distillation tower overhead systems and downstream thereof. A lowering of the presence of water in the feed prior to contacting thereof with the molecular sieve brings a significant reduction in corrosion downstream. At the same time, it has a significant beneficial effect on catalyst activity and brings a significant extension of catalyst life. Lowering water in the feed is particularly effective when organic nitrogen-containing Lewis bases are present in the feed, even at low levels.

摘要: The conversion and run length for oligomerization of olefins over a molecular sieve catalyst in a tubular reactor is improved by controlling the peak temperature to not exceed 50 degrees C. above the temperature of the temperature control fluid exiting the shell side outlet of the reactor. A tubular reactor containing molecular sieve catalyst is provided with a multipoint thermocouple in at least one tube, and optionally with a bottom design adapted for fast unloading of the molecular sieve catalyst from the tubular reactor.
