Abstract: The present application describes an integrated process for the manufacture of biodiesel from vegetable or animal oils using a solid, transesterification catalyst and a solid, etherification catalyst.

Abstract: An apparatus for generating a biocidal agent in a gaseous state. The apparatus includes a first monolith and second monolith. The first monolith includes a surface impregnated with an acid, while the second monolith includes a surface impregnated with a compound. The apparatus further includes a means for directing a gas that includes moisture sequentially to the first monolith and then to the second monolith. A gaseous stream that includes moisture having passed through the first monolith carries an acid vapor desorbed from the surface of the first monolith to the compound of the second monolith, whereby a stream of biocidal agent in a gaseous state is generated.

Abstract: A method for producing novel catalysts comprising of Group VIII metal along with a partially reducible metal oxide, zirconium oxide, lanthanum oxide and aluminum oxide is disclosed. These novel catalysts retain their catalytic activity even in the presence of significant quantities of sulfur compounds. This makes them attractive in the conversion of hydrocarbons into hydrogen; a process for the same is also disclosed.
