The invention provides composites of organic polymeric compositions including a matrix of an organic polymer and a filler distributed throughout the matrix, the flier being present in the matrix substantially as separate particles, each about the fundamental particle size of the filler. The fillers are unique mixed metal hydroxide compositions that are obtainable in sub-micron size particles. These particles are layered and have a BET specific surface area in excess of about 100 m.sup.2 /g. An anion of the particulates is selected to be compatible with the organic polymer thereby providing ease of dispersion of the filler particles throughout the polymer matrix.

Polymeric composites with crystalline mixed metal hydroxide particles

Coating formulations which behave as elastic solids having reversible stress-induced fluidity are prepared by creating a fluid having distributed therein effective amounts of ionic charge sites and countercharge sites. For instance, elastic solids having reversible stress-induced fluidity are prepared by combining liquid formulations with a dispersion of a small, but effective, amount of at least one crystalline mixed metal hydroxide conforming substantially to the formula

Adducts of clay, especially of the smectite variety, most especially bentonite, are prepared with an effective amount of at least one activated mixed metal oxide or oxy-hydroxide (AHMMO) formed by dehydrating hydrotalcite or a mixture comprising magnesium oxide and aluminum oxide, or a crystalline mixed metal hydroxide conforming substantially to the formula

Adducts of clay and activated mixed metal oxides

Formulations or products are caused to be active antimicrobials by the addition thereto of at least one effective amount of at least one crystalline mixed metal hydroxide (MMOH) conforming substantially to the formula

Antimicrobial positively charged particles

Aqueous-based functional products or corrosive products such as cleansers, household products, commercial products, and personal care products are thickened or viscosity-modified by the addition of at least a small, but effective, amount of at least one crystalline mixed metal hydroxide conforming substantially to the formula

Viscosity-modifiers for aqueous-based functional products containing

A catalyst composition comprising a catalytic metal and a support, the support being prepared by depositing a metal alkoxide on a core support, then calcining the support.

Catalysts having alkoxide-modified supports

Cracking of crude oil or crude oil residues is accomplished in an adiabatic reactor which follows a partial combustion zone with the injection of superheated or shift steam into the combustion gases. Advantages are that the carbon monoxide produced by partial combustion is converted to carbon dioxide which is easily removed, there is no need to supply a separate source of fuel or hydrogen, and coke formation is substantially eliminated. The cracked oil produced in the process can be used as a quench oil and/or fuel to feed the partial combustion zone. The yields of olefins and aromatics is increased over processes using superheated steam cracking.
