    摘要： A hydroprocessing trickle reactor construction which will facilitate the catalytic dewaxing of liquid petroleum or lube feedstocks in a highly efficient and economical manner, particularly through the use of reactors employing stationary bed of a defined, shape-selective crystalline aluminosilicate zeolite catalyst, preferably ZSM-5. Pursuant to one embodiment of the hydroprocessing reactor, the latter is essentially constituted of a trickle bed reactor wherein a plurality of vertically tiered and staggered trays support the beds of catalyst material, such as the crystalline zeolite, and through which the liquid petroleum feedstock trickles downwardly from the upper end of the reactor, while hydrogen is concurrently injected into the catalyst on each of the trays. This causes the hydrogen to percolate through the catalyst bed and to contact and efficiently strip the downwardly trickling stream of liquid petroleum feedstock of low boiling conversion products or waxy components, such as naphtha. Pursuant to a second embodiment of the hydroprocessing catalystic reactor construction, inclined supporting stationary beds of catalyst are vertically tiered with the liquid petroleum stock trickling down through the reactor so as to enter the upper portion of the bed contained in each tray, flowing along the inclined tray surface thereof forming a liquid seal along the bottom surface of each tray and forcing hydrogen introduced into each tray to flow upwardly through the catalyst bed and react with the liquid petroleum feedstock. The liquid is directed to trickle downwardly to a lower catalyst bed through the interposition of suitable baffles, whereas hydrogen gas inclusive of low boiling, volatile conversion products stripped from the liquid petroleum in the catalyst beds flows upwardly through passages beneath the baffles into a central vertical conduit in the reactor, from when they are conducted by being entrained in an upwardly-flowing carrier gas out of the upper end of the reactor.

    摘要： A reactor for catalytically dewaxing a waxy distillate consisting of a lubricating oil or liquid petroleum feedstocks utilizing a shape-selective crystalline aluminosilicate zeolite catalyst in order to obtain a lubricating oil having a low pour point and a high viscosity index, particularly, a plate-type hydroprocessing trickle reactor construction for catalytically dewaxing liquid petroleum feedstocks. The reactor is essentially constituted of an inclined plate trickle bed reactor wherein a tray of generally permeable construction supports a bed of catalyst material, such as crystalline zeolite, and in which the liquid petroleum feedstock trickles downwardly through the catalyst material from the upper end of the reactor towards the lower end of the reactor, while hydrogen is concurrently injected into the space below the permeable tray at the upper end of the reactor in the direction towards the lower end of the reactor. The hydrogen, under a slight superpressure passes through the permeable plate and percolates through the catalyst bed to thereby contact and efficiently strip the downwardly trickling stream of liquid petroleum feestock of low boiling conversion products or waxy components, such as naphtha. The generated gases resulting from the reaction, such as hydrogen, naphtha and LPG are collected in a head space provided above the catalyst bed on the permeable plate, and are scavenged at one end of the reactor through entrainment in an inert carrier gas introduced into the reactor at the opposite end thereof and which flows through the head space above the catalyst.

    摘要： A method for suppressing light gas production in a cracking process by dispersing in the feed low concentrations of a highly siliceous material having high surface area and low acidity prior to cracking. Because of the high surface area-to-volume ratio of the particles, the catalyst acts as a free radical scavenger which reduces the amount of light gas produced by free radical-promoted reactions.
