摘要： The catalytic activity of a chromium oxide-based catalyst used in the production of chlorine by oxidation of hydrogen chloride gas with an oxygen-containing gas is regenerated by impregnating it with an aqueous solution of chromic acid anhydride or of a chromium salt and then calcining the catalyst at a temperature not higher than 800.degree. C.

摘要： A method for preparing acrolein or methacrolein comprises subjecting propylene, secondary propanol, isobutylene or tertiary butanol to gas phase catalytic oxidation with molecular oxygen in the presence of a catalyst represented by the following general formula (I):Mo.sub.a Bi.sub.b Fe.sub.c X.sub.d Y.sub.O Z.sub.f O.sub.g (I)wherein X represents at least one element selected from the group consisting of Ni and Co; Y represents at least one element selected from the group consisting of K, Rb, Cs and Tl; and Z represents at least one element selected from the group consisting of Be, Mg, Ca, Sr, Ba, Ce, Ti, Zr, Nb, Cr, W, Mn, Cu, Ag, Zn, Cd, B, Al, Si, Ge, Sn, Pb, P, As, Sb, S, Se and Te; a, b, c, d, e, f and g each represents an atomic ratio of the corresponding element and when a is assumed to be 12, b=0.1.about.10, c=0.1.about.20, d=2.about.20, e=0.01.about.2, f=0.about.4 and g represents the number of oxygen atoms required for satisfying the valency requirement of the constituent elements, wherein the catalyst used is prepared by separately preparing solutions each of which contains the starting compound for the foregoing catalyst components, mixing these solutions within a short period of time, spray-drying the resulting mixture immediately after the mixing and then calcining the dried powder. A catalyst which further comprises 5 to 15% by weight of silica in addition to the foregoing composition is also used in the method. End products can be obtained in high conversion and selectivity through the use of the foregoing catalyst. Moreover, the catalyst is excellent in stability and has good reproducibility.

摘要： A hydraulic auto-tensioner includes a high-pressure oil chamber and a low-pressure oil chamber, and oil (L) in the high-pressure oil chamber passes through a clearance (G) between a cylinder (17) and a piston portion (18) of a plunger and leaks into the low-pressure oil chamber from an end of the clearance (G) near an end surface of the cylinder (17). A recessed groove (40) is provided in an inner peripheral surface of the cylinder (17) by a conical surface (41) having a groove angle of 5 to 15 degrees from the end of the clearance (G), a throttle portion (45) projecting onto the piston portion (18) side is provided further toward the end surface side of the cylinder than the groove (40) in the inner peripheral surface of the cylinder (17), and a throttle gap (A) larger than the clearance (G) is formed between the throttle portion (45) and the piston portion (18).
