Abstract:

A solid, pulverulent composition for destroying pathogen activity and absorbing liquid when placed in contact with blood spills consists essentially of a chlorine source capable of yielding hypochlorous acid in contact with water, such as calcium hypochlorite, and diatomaceous earth. The composition includes sufficient of the chlorine source to provide an available chlorine level in the composition of at least 5,000 ppm and, preferably, 5,000 to 65,000 ppm.

Abstract:

A methanol conversion process comprises contacting a feedstream comprising methanol, optionally with dimethyl ether or other oxygenates with a catalyst comprising a physical mixture of a molecular sieve, preferably an intermediate or small pore size zeolite such as an MFI zeolite, with a basic metal oxide to provide extended catalyst cycle life by reducing the incidence of coke formation. The process may be applied to the methanol-to-gasoline (MTG), methanol to distillate (MOD), methanol-to-olefins (MTO), methanol-to-chemicals (MTC) and combination processes such as the MTO/OCP Process.
