Abstract: Disclosed is a process for generating synthetic fuels from carbonaceous minerals such as oil shale and coal by dispersing a catalytic agent by suitable explosive means into carbonaceous deposits. The explosives serve to fracture and rubblize the carbonaceous mineral as well as conveying the catalyst onto and in close proximity to the fractured particles. The catalyst coated particles are then converted, in whole or part, to gaseous and liquid products by conventional processes such as retorting, gasification, hydroretorting, hydrogenation, or the like, wherein this process or part of it is accelerated, decelerated, or otherwise favored by the presence of the catalytic agent. This process is capable of producing an increased yield and/or better quality product since it is possible to maintain greater control over the conversion step.

Abstract: The particle size of as formed polyethylene or ethylene copolymer containing up to about fifteen percent of a C.sub.3 to C.sub.8 olefin, which is made using a promoted solid catalyst component prepared from a magnesium alkoxide, a titanium (IV) alkoxide and an alkylaluminum dichloride, is increased by adding the dichloride in at least two stages and allowing the preparation mixture to age between stages during the preparation of said catalyst component. The particle size of polymer can be increased substantially using the so treated catalyst component, compared to the particle size of polymer made using untreated catalyst component, when either catalyst component is employed together with an alkylaluminum compound promoter in a slurry or vapor phase process at moderate polymerization temperature and pressure.

The catalyst produces polyolefin in good yield without any substantial production of polymer fines and the catalyst is quite sensitive to hydrogen induced chain termination processes leading to improved molecular weight control and rheology of the polymer product.
