Patent number: 5597416Abstract: The present invention is a new crystalline sugar product and method of making same which includes forming a bi-dimensionally stabilized sugar crystalline frame from an outer portion of an amorphous shearform sugar mass, and, subsequently, converting the remaining portion of the mass to a substantially completely crystalline structure which retains the cross-sectional dimension of the sugar crystalline frame. The present invention also includes co-crystallizing an additive, especially a bio-affecting additive, during the process to provide a co-crystallized product.

Patent number: 5538624Abstract: An improved catalytic process for heavy hydrocarbon conversion (usually but not necessarily in the presence of nickel and vanadium in the feedstock and on the catalyst) to produce lighter and selective molecular weight fractions. This process is specifically targeted as a means of retaining specialty high-valued, preferably microspherical additives (SHVA) which assist in attaining preferred conversion products such as gasoline, especially the recent gasolines meeting compositional requirements of "Reformulated Fuel".Selective magnetic retention of these high-cost specialty additives can be achieved by incorporating into them selective magnetic moieties, preferably manganese, the heavy rare earths and superparamagnetic iron. Selective retention is achieved by passing spent or regenerated catalyst containing small amounts of these SHVAs through a magnetic separator, and selectively recycling them back to the circulating catalyst.Type: GrantFiled: October 21, 1994Date of Patent: July 23, 1996Assignee: Ashland Inc.Inventor: William P.
