Processes for reforming, and in particular aromatising, hydrocarbons from a petroleum source may be carried out by contacting the hydrocarbons with a catalyst of a zeolite KL impregnated with a metal promotor such as platinum, in which the zeolite crystals are of hockeypuck shape. 0 to detoxify the agents and to render them suitable for disposal. The lock arm is resiliently deformable between an engaging position where it is engageable with a slider assembled into the female housing and a disengaging position where it is disengaged from the slider. The authorization map is kept in a memory space in one of the plurality of nodes. 05 mmoleskg polymer of each of the following ionic end groups: COF, COOH, their esters or salts, when the used determination method for said end groups is the Fourier Transform IR spectroscopy by Nicolet Nexus FT-IR equipment . Thus, the six hues and six inter-hue areas can be varied independently, and the large-capacity memory is not required.
