Title: An improved cleaning composition.
Inventor: BARNETT CHRISTOPHER C
IPC: C11D7/42
Filed: 1995-08-09
Abstract: Novel alpha-amylase mutants derived from the DNA sequences of naturally occurring or recombinant alpha-amylases are disclosed. The mutant alpha-amylases, in general, are obtained by in vitro modifications of a precursor DNA sequence encoding the naturally occurring or recombinant alpha-amylase to generate the substitution (replacement) or deletion of one or more oxidizable amino acid residues in the amino acid sequence of a precursor alpha-amylase. Such mutant alpha-amylases have altered oxidative stability and/or altered pH performance profiles and/or altered thermal stability as compared to the precursor. Also disclosed are detergent and starch liquefaction compositions comprising the mutant amylases, as well as methods of using the mutant amylases. More particularly preferred are mutant alpha-amylases from Bacillus licheniformis modified at MET197 or MET15 or at TRP138 residues or at equivalent residues of other alpha-amylases from other microbial sources (Bacillus, Aspergillus).

IPC: C12P37/04
Filed: 1996-03-25
Abstract: Process for the recovery of ampicillin from a mixture containing ampicillin and 6-aminopenicillic acid (6-APA), in which a mixture of ampicillin and 6-APA, with a pH higher than 7, which apart from any solid ampicillin being present is homogeneous at a pH between 7 and 8.5, is subjected to a pH lowering till a pH lower than 8.2 is reached, and the solid substance present is recovered. The process is in particular suitable to be applied to the reaction mixture which is obtained after the enzymatic acylation reaction of 6-APA with a phenylglycidine derivative as acylation agent. Pure ampicillin can thus be recovered in a simple way.

Title: Reducing the Conradson carbon and metals content of heavy oils - by mild cracking in riser reactor
IPC: C10G25/09
Filed: 1982-04-02
Abstract: Selective vaporisation process for reducing the Conradson carbon (CC) and metals content of heavy petroleum fractions comprises contacting the feed and inert gas with a finely divided inert solid material in a riser reactor under mild cracking conditions, including a high temp. and a short hydrocarbon residence time. The vapour-phase prods. are sepd. from the solids and are cooled to a temp. below that at which significant thermal cracking occurs. The solids are contacted with an oxidising gas to burn off coke deposits and heat the catalysts (sic) to high temp., whereupon the heated solids are returned to the lower part of the riser. The improvement comprises introducing the inert gas into the lower part of the riser and injecting the feed into the riser at a point situated in or above the lower part. The process is esp. useful for producing FCC feedstocks from petroleum residua. Injection of the inert gas as above provides provides greater flexibility in the feed injection rate and/or in the control of the residence time in the riser.
