NOVELTY - Producing (M1) biochar pellets involves mixing biochar with at least one additive and water to result in a mixture; extruding the mixture to result in an extrudate; cutting extrudate into pellets; heating pellets for a predetermined time at a predetermined temperature and then cooling the pellets; and processing pellets in a spheronization device which heats pellets and forces pellets to tumble against one another while being heated.    USE - For producing biochar pellets useful in a biochar product which may be used in biodiesel manufacturing; animal feed supplement; esterification reactions; transesterification reactions; organic solution dessicant; or liquid hydrocarbon mixture dessicant (claimed).    ADVANTAGE - The sulfur-containing coating can be a porous coating with minute holes over its surface, where porosity can be controlled by controlling coating thickness. The thickness and porosity of the sulfur-containing layer can be adjusted to balance biochar exposure and other desirable properties such as bulk density and mechanical strength of the coated particles; and to provide exposure of the highly porous biochar to the surrounding environment. This allows water from the surrounding soil to adsorb into the particle and aid in breakdown of the coating. The biochar particles thinly coated with a sulfur-containing coating retain their granular nature, while showing improved mechanical strength, thus reducing charcoal pulverization and preventing subsequent loss of product as dust when handled with agricultural equipment. The coated biochar particles also reduce the hazards of dust self-ignition and potential lung contamination due to dust inhalation. The addition of inert substances such as chalk or clay to the sulfur blend increases overall bulk density and creates minute discontinuities in the coating resulting in greater porosity. The method creates a biochar that mimics commercial fertilizers used in prior art, and allows distribution in the form of a biochar-fertilizer blend during handling and spreading. By increasing bulk density and adding a protective coating, as well as promoting the spheronization of the pellets, the handling characteristics of the final product are improved. This, in turn, allows easier product distribution by conventional agriculture fertilizer spreading equipment. The coated biochars can withstand the rigors of agricultural application equipment and provide a cost-effective option of reinforcing biochar particles with firm porous coatings. The biochar pellets manufactured using the above procedure is inert to biodiesel at room temperature, i.e. they do not catalyze or react chemically with biodiesel. These biochar pellets absorb unwanted biodiesel contaminants such as water and glycerol. The biochar pellets also maintain their shape and do not dissolve (up to 48 hours tested), so the pellets are easily removed from the biodiesel. Adding sulfur in the biochar pellets when used as dietary supplement can improve ruminant health if the animals are raised in areas where the soils have low quantities of the mineral.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a biochar product comprising a porous biochar pellet having additives selected from gluten, sulfur, and lignin.
