Publication number: 20100162780Abstract: Methods and apparatuses for depositing agents relatively deep within pores of bio-char. Bio-char is first produced in an airtight oven by heating biomass feedstock. The bio-char is then cooled and steam is diffused into the pores of the bio-char. The steam-laden bio-char is immersed in a liquid bath containing soluble agents that are to be deposited in the pores of the bio-char. The liquid bath cools the char to below the condensation temperature of the steam, whereupon the condensing steam generates a partial vacuum within the pores, drawing the liquid into the pores. The bio-char is then removed from the liquid bath and dried so that the liquid within the pores evaporates, leaving behind the soluble agent. Accordingly, the invention yields bio-char that has soluble agent embedded relatively deep within its pores.Type: ApplicationFiled: December 31, 2008Publication date: July 1, 2010Inventor: Gerald C.

Patent number: 5451242Abstract: A synthetic soil/fertilizer for horticultural application having all the agronutrients essential for plant growth is disclosed. The soil comprises a synthetic apatite fertilizer having sulfur, magnesium and micronutrients dispersed in a calcium phosphate matrix, a zeolite cation exchange medium saturated with a charge of potassium and nitrogen cations, and an optional pH buffer. Moisture dissolves the apatite and mobilizes the nutrient elements from the apatite matrix and the zeolite charge sites.Type: GrantFiled: May 2, 1994Date of Patent: September 19, 1995Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Douglas W. Ming, Donald L. Henninger, Earl R. Allen, Dadigamuwage C. Golden

Patent number: 5447637Abstract: Phossy water is a toxic liquid waste that is generated when elemental phosphorus is manufactured, stored, or processed into phosphorus-containing products. Elemental phosphorus may be present as a solution, as colloidal particles, and as settleable particles.The primary objects of the invention are as follows:1. To provide a process for the disposal of phossy water stored at the TVA National Fertilizer and Environmental Research Center.2. To provide a process for the recovery of phossy water that will be generated when hazardous wastes stored at the TVA National Fertilizer and Environmental Research Center are recycled.Phossy water can be disposed of by using it to quench and granulate molten slag at electric furnaces used to manufacture elemental phosphorus. The elemental phosphorus content of the phossy water is limited to about 2 parts per million.Type: GrantFiled: September 21, 1994Date of Patent: September 5, 1995Inventor: James C. Barber

Patent number: 5433766Abstract: A synthetic apatite containing agronutrients and a method for making the apatite are disclosed. The apatite comprises crystalline calcium phosphate having agronutrients dispersed in the crystalline structure. The agronutrients can comprise potassium, magnesium, sulfur, iron, manganese, molybdenum, chlorine, boron, copper and zinc in amounts suited for plant growth. The apatite can optionally comprise a carbonate and/or silicon solubility control agent. The agronutrients are released slowly as the apatite dissolves.Type: GrantFiled: May 2, 1994Date of Patent: July 18, 1995Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Douglas W. Ming, Dadigamuwage C. Golden
