(ln Gcrnlall) Discusses the effects of microbial colonization on mineral oil-based and biodc~dablc mineral oil-free h draulic fluids and on different clean water qualities. Changes in hydraulic i ud quality resulting from microbial mctabolic processes were evident in HFA-t fin-resistant hydraulic fluids and in colonized clean water. Rapid bio *Fogxal degradation of the concentrate with a clear deterioration m the chemical and technical properties cccurrcd in the mineral oil-free HFA-S-type hydraulic fluid. The hydraulic fluids have application in coal mining.

Apr. 1994. The process for the manufacture of A-type zeolites involves: stirring coal aah in an alkali solution at 60-900 for a ocriod between 30 minutes and 5 hours, and adding an Al souse, Na so&e, and water, and stirring by heating for reaction. Thus A-type zeolite was prepared by using Na alurmnate, NaOH, and waste coal ash. Manufactun of activated brown coal Kopischke, H. J. et al, (Assignedto) LausitzerBraankohleAktiengesells&a& GER.

(In ChillCSe) The heavy fraction of light diesel oil (LDOHF), derived from petroleum naphtha catalytic cracking was used as a coking additive co-carbonization of medium coal tar itch with petroleum heavy oils. The structural characteristics of LDOH% before and after co-carbonization were studied by NMR spxtroscopy.

Molecular weight determination is necessaryfor the structural analysis of potential lubricating oil products derived from oil shale. Tbrcc methods -vapour pressure osmomctry, gel permeation chromatography and viscosity correlation - for determining the number-average molecular weight of samples derived from the processing of Rundle and Stuart shale oils were studied. Three petroleum-derived lubricating oil base stocks were also analyscd for comparison. Results from the three methods for pctroleumderived base stocks were in reasonable agreement.

A fluid&d sand &d na&r was us& to study the irodk$on of gases from 1 ethylene (HDPB) at five nominal temperatures (ran to &d. Both HDPB pnmary decomposition and wax cra~gk~~~ take place inside the reactor. Yields of 13 pyrolysis producta (methane, ethane, ethylene, pro ant, pro ylene. acetylene, butane, butylene. pentane, benzene, tolucne, xy Pencs, anB styrcne) were analyzed as a function of the operating conditions. The results are compared with the data obtained by pyrolysis of HDPE in a Pyroprobc 1000, where secondary wax and tar cracking is small.
