Catalytic decomposition of hydrocarbon into hydrogen and carbon in a spouted-bed reactor as the second-stage reactor of a plastic recycling process

A two-stage process for the chemical recycling of plastics is proposed. In this process, which consists of two reactors, plastics are converted into hydrogen and carbon. In the first reactor, plastic chips are thermally decomposed into hydrocarbons. In the second reactor, the hydrocarbons formed in the first reactor are catalytically decomposed into carbon and hydrogen. In this study, in order to obtain basic data for the second reactor, propene was catalytically decomposed in a laboratory-scale spouted-bed reactor (600mm high, 21.6mm internal diameter, made of SUS304). The effect of the type of spouting medium used on the decomposition behavior of propene was investigated using four types of spouting medium (nickel-plated -alumina, palladium-plated -alumina, nickel-impregnated -alumina, and -alumina). The nickel-impregnated -alumina gave the best propene conversion and hydrogen yield.

Manufacture of strand board made from construction scrap wood

The objective of this research was to evaluate the physical and mechanical properties of strand board made from construction scrap wood. The strand board was manufactured using Sugi (Cryptomeria japonica D. Don) and Douglas-fir (Pseudotsuga japonica) strands selected from construction scrap wood. The strands were oriented, and three-layer (face/core/face) strand board of three types was produced: one in which the strands of the face layer were oriented at a right angle to those of the core layer (R board), another in which the strands of the face layer were oriented parallel to those of the core layer (P board), and a third in which the strands of both layers were oriented at random (Ra board). The physical and mechanical properties of the boards were evaluated based on Japanese Industrial Standard (JIS). The main results obtained are as follows: the bending strength of the strand board with a density larger than 0.55 g/cm³ exceeded the standard value of type 18 particleboard of JIS A 5908. The bending strength of the strand board was affected by board density, strand orientation and resin content, and became larger with increased density as well as resin content. That of the parallel specimen of P board was the largest among the specimen-orientations and types. The internal bond strength of the strand board with a density larger than 0.55 g/cm³ exceeded the standard value of type 18 particleboard and type 24-10 particleboard of JIS A 5908. The internal bond strength was markedly affected by the resin content of the core layer, and became larger with increased density. The thickness swelling of the strand board decreased with increased resin content, and become larger with increased density.     

Technological improvements in automotive battery recycling

Recycling of automotive batteries for the recovery of secondary lead is extremely important in Brazil, for the country does not possess large reserves of this metal. Lead is one of the most widely used metals in the world, but it is highly toxic, posing risks for humans and for the environment if not utilized or treated adequately. Industrial waste containing lead in Brazil are classified by the Brazilian Residue Code (NBR—10004:2004) as hazardous. The lead recycling process employed by the recycling industry in Brazil is the pyrometallurgical process in a rotary furnace. This process consists of four stages: (1) grinding of the battery to separate plastic, electrolyte and lead plates; (2) lead reduction in a rotary furnace; (3) separation of metallic lead from slag; and (4) refining of recycled lead. The purpose of this work is to propose process improvements aimed primarily at increasing production output by reducing the loss of lead in slag and particulates, thereby providing a healthier work environment in line with Brazilian environmental and labor laws.

THE CIRCUIT RIDING ORDINANCE ADMINISTRATOR: A SOLUTION TO SMALL COMMUNITY TECHNICAL INADEQUACIES1

ABSTRACT: Small, rural communities (less than 2500 population) in general do not have governmental staffs with the breadth required to satisfactorily implement and enforce a drainage ordinance. This fact has serious implications in rural Planning. Within a six-country rural area of Southwest Virginia, the circuit riding town manager program has been successfully conducted. The circuit riding town manager is a planning staff member who acts in the capacity of a town manager (assistant to the mayor) for five small towns, any one of which alone could not afford to support the services of such a professional. This note recommends that a circuit riding technical ordiance administrator program could be developed along the same lines. In this manner, the technical ordinance program for serveral small communities could be successfully implemented.
