    摘要： A fluid cat cracking process for catalytically cracking a feed containing vanadium into lower boiling products, includes a cat cracker and a regenerator, with the feed entering the catalytic cracking zone preheated by indirect heat exchange with spent, stripped catalyst particles being recycled from the cracking reactor to the regenerator. Operating the regenerator at a temperature no higher than about 1150.degree. F. permits the amount of vanadium in the feed to be substantially increased with no loss of catalytic activity due to vanadium poisoning of the catalyst, when compared to a higher regenerator temperature of 1365.degree. F. Using the stripped, spent catalyst for heating the feed reduces feed coking and heat exchanger fouling, compared to using the hotter regenerated catalyst for feed preheat.

    摘要： Processes for the production of hydrogen cyanide from the reaction of methane with ammonia at temperatures above about 800.degree. C. where the reactor contains a matrix bed of heat resistant materials. The product stream produced within the reactor is preferably routed in a countercurrent fashion to the feed stream entering the reactor to preheat the feed stream and to lower the exit temperature of the product stream. Reactors capable of being used to practice such processes are also provided by the invention.

    摘要： Integral coupling of reaction with a single-bed rapid cycle pressure swing adsorber provides a hybrid device having improved performance characteristics including better separation and more efficient reactions. A single packed bed containing a mixture of catalyst and adsorbent is featured. Gaseous reactants are fed into the bed in a sequence including inflow, relax, and backflow, portions. The hybrid device, designated as a periodic separating reactor (PSR), enhances both the total conversion and selectivity of reactions. In an illustrative example with respect to CO oxidation, conversion 2.5 times that typically exhibited for the corresponding steady-state plug flow reactors was observed. The separation performance (selectivity) of the hybrid device/process can be enhanced, illustratively for irreversible reaction systems, up to 10.sup.4 times that possible in pressure swing adsorption processes without reaction. The particular exit stream in which a component is enriched is a function of reaction rates, feed composition, adsorption capacities, delivery flow rate, and the feed fraction of the process cycle. Separation between reaction components, local reduction of reactant partial pressures, changes in the residence time distribution, and the nature of the reaction rate law contribute to the observed process performance. A modeling scheme is proposed to describe the behavior of the hybrid device and the expected results from application of the process to any particular reaction.
