Abstract: A fixed bed hydroprocessing system, and also a method for upgrading a pre-existing fixed bed hydroprocessing system, involves preliminarily upgrading a heavy oil feedstock in one or more slurry phase reactors using a colloidal or molecular catalyst and then further hydroprocessing the upgraded feedstock within one or more fixed bed reactors using a porous supported catalyst. The colloidal or molecular catalyst is formed by intimately mixing a catalyst precursor composition into a heavy oil feedstock and raising the temperature of the feedstock to above the decomposition temperature of the precursor composition to form the colloidal or molecular catalyst in situ. Asphaltene or other hydrocarbon molecules otherwise too large to diffuse into the pores of the fixed bed catalyst can be upgraded by the colloidal or molecular catalyst.  One or more slurry phase reactors may be built and positioned upstream from one or more fixed bed reactors of a pre-existing fixed bed system and/or converted from one or more pre-existing fixed bed reactors.

Abstract: Ensemble de verrouillage de porte électrique comprenant un solénoïde comportant un piston mobile entre les positions rétractée et allongée, de même quun support de fixation permettant de fixer le solénoïde à une porte ou à un cadre de porte pour que le piston se déplace de façon fonctionnelle le long dun axe vertical entre les positions rétractée et allongée. Un bras ou un boulon de verrouillage est raccordé de façon pivotante, à une extrémité proximale, au piston. Un ensemble de raccord entraîne le pivot rotationnel et linéaire du bras par rapport à un axe horizontal, à mesure que le piston passe de la position rétractée à la position allongée, pour quune extrémité distale du bras passe dune position déverrouillée à une position verrouillée par rapport à une gâche de la porte. Cet ensemble peut prévoir que le bras de verrouillage est doté dune fente axiale allongée dans laquelle une tige fixe du support de fixation est positionnée; de plus, la tige pivot définit laxe horizontal. Lextrémité proximale du bras de verrouillage est raccordée de façon pivotante au bas du piston. Ainsi, à mesure que le piston se déplace de haut en bas, lextrémité proximale se déplace de haut en bas et le bras de verrouillage coulisse par rapport à la tige, entraînant ainsi un mouvement de pivot rotationnel et linéaire.
