Hydrorefined hazel-nut oil was mixed with liq. paraffin and hydrogenated at 320-340°C under 3 MPa in a flow reactor (9-20 h-1) over a com. NiMo catalyst to det. the kinetics of hydrocarbon formation. Mechanism of the reaction was discussed.

Camelina oil was hydrotreated at 320°C in a mixt. (20% by vol.) with middle distillate b. 160-245°C from crude oil to remove unsatd. fatty acids. The H2 consumption was by 20% higher and the cloud point of the hydroraffinate by 1% higher than in the case of rapeseed oil.

Rapeseed oil was converted on ZSM-5 zeolite catalyst at 200-300°C and 1.7 MPa under N 2 and then hydrorafined at 320°C and 3.0 MPa under H 2 to produce a hydrocarbon fuel component with an increased content of iso-paraffins. The zeoforming resulted in a decrease of cloud point temp, of a mixt. of com. crude oil fraction b. 160-245°C and the zeoformate (20%) down to -10.2°C (from -6.2°C).

Silicate gels were prepd. by addn. of HCOOH to water glass and studied for gelation time, viscoelastic properties and shrinkage behaviour at varying pH of the sol-gel transformation. The gels produced at pH 9.5-10.5 showed the best applicability for modification of permeability of petroleum reservoir rocks.
