摘要： Disclosed is a method of recovering olefin from purge streams in a polyolefin production process. The method includes reacting a purge stream containing olefin and impurities with water in the presence of a hydrating catalyst to produce an alcohol containing stream. The impurities can include methane, ethane, butylenes, and hydrogen. The alcohol containing stream can be used to produce olefins in an oxygenate to olefin production process.

摘要： Presented is a method and apparatus for converting both organic and inorganic materials into more desirable products by the expedient of breaking down these materials into their stable molecular constituents and reforming them into more desirable substances. The process involves the use of two chambers. Blended solid and fluid wastes are augered into the first chamber and agitated, preferably by rotating the chamber so that the waste tumbles over internal fins, while a heat gradient is applied. Carbon and inorganic solid wastes are removed from the system and fluid wastes passed to a second chamber where they are again subjected to a heat gradient. Effluents are recovered and condensed. Electromagnetic radiation, preferably from microwaves, and/or lasers, masers or ultrasonic energy is applied to the wastes in both chambers. Liberal use of catalysts is made in the chambers. In addition, the augering system is based on the use of two, counter-rotating, inter-lapped, symmetric augers for positive feed of materials.

摘要： Disclosed is a molecular sieve catalyst which contains molecular sieve-containing attrition particles and virgin molecular sieve, the attrition particles having been recycled from a catalyst manufacture process or from a reaction system. The catalyst can be used in a variety of catalytic reaction processes. A desired process is making olefins from an oxygenate feedstock. The recovery and use of the attrition particles in the catalyst is beneficial in minimizing waste, thereby reducing problems relating to both environmental and economic constraints.

摘要： A process for converting methanol to light olefins is disclosed and claimed. The catalyst is a metalloaluminophosphate molecular sieve having the empirical formula (ExAlyPz)O2 where EL is a metal such as silicon or magnesium and “x”, “y” and “z” are the mole fractions of EL, Al and P respectively and specifically where “x” has a value of about 0.02 to about 0.08. A preferred molecular sieve is one which has predominantly a plate crystal morphology in which the average smallest crystal dimension is at least 0.1 microns and has an aspect ratio of no greater than 5. The process provides greater selectivity to ethylene and propylene versus C4+ byproducts.

摘要： A process for increasing the ethylene selectivity of a silicoaluminophosphate molecular sieve catalyst by using acetone in an oxygenate conversion process. Acetone can be added with the oxygenate feed at a concentration from about 1% to about 15% by weight, preferably about 1% to about 8% by weight, more preferably about 2% to about 5% by weight. Alternatively, acetone can be added as a pre-feed to the molecular sieve catalyst, particularly regenerated and fresh catalyst, in an contact zone. The pre-feed contacted catalyst is then directed to an oxygenate conversion zone. The acetone concentration in the pre-feed is from about 1% to about 99% by weight, preferably about 30% to about 70% by weight.

摘要： The present invention provides a method and apparatus for maintaining the active life of a catalyst in organic feed processing by applying a series of electromagnetic radiation pulses to the catalyst in a reactor. The pulsing of the catalyst selectively heats and cools the catalyst and can regulate the relative internal pressure of the catalyst particles to stimulate the acceleration of oil macromolecules mass-exchange through the catalyst pores and surface. This allows for the removal of cracked oil molecules from the particles. The application of electromagnetic pulses also regulates the activity of the catalyst. The electromagnetic radiation reduces the formation of coke on the catalyst and increases the life of the catalyst in the reactor. Further, the present invention provides a method and apparatus for removing water and salt from an organic feed. Water and salt is removed by applying a series of electromagnetic radiation pulses to the organic feed.
