Abstract
A method of operation for producing high yield of alkylate product using catalytic reactors. The catalytic reactors which cycle between reaction mode and catalyst regeneration mode have their contents exchanged with each other at the beginning of each cycle in order to increase the yield of the desired product. This exchange increases the yield by minimizing the contact of reactant in reaction mode with regenerant utilized in regeneration mode. Thus, reducing/preventing the undesirable alternate reaction between the two, which consumes the reactant making it unavailable for the production of the desired product.
Claims6
A method of producing high yield of alkylate product from an alkylation process utilizing first and second reactors having a liquid content comprising the steps of:
- reacting an alkylatable organic compound with an alkylation agent in the first reactor containing a first solid acid catalyst to produce an alkylate product;
- feeding a portion of said alkylate product to a second reactor;
- contacting a second solid acid catalyst simultaneously with hydrogen and the fed portion of the alkylate product in the second reactor to regenerate the second solid acid catalyst;
- exchanging the liquid contents of the first reactor with the liquid contents of the second reactor;
- reacting the alkylatable organic compound and the alkylation agent in the second reactor using the regenerated second solid acid catalyst to produce an alkylate product;
- and
- contacting a saturated hydrocarbon and hydrogen in the first reactor to regenerate the first solid acid catalyst.
